Analysis of factors affecting the performance of activated peroxide systems on bleaching of cotton fabric was written by Fei, Xiuzhu;Yao, Jinlong;Du, Jinmei;Sun, Chang;Xiang, Zhonglin;Xu, Changhai. And the article was included in Cellulose (Dordrecht, Netherlands) in 2015.Reference of 10543-57-4 This article mentions the following:

A screening experiment was designed to investigate the possible factors affecting the performance of activated peroxide systems (APSs) on bleaching of cotton fabric. The design of experiment comprised thirteen factors such as type of bleach activator (BA), concentration of bleach activator ([BA]), molar ratio of hydrogen peroxide to bleach activator ([H₂O₂]:[BA]), type of peroxide stabilizer (PS), concentration of peroxide stabilizer ([PS]), type of wetting agent (WA), concentration of wetting agent ([WA]), pH value of bleach bath (pH), bleaching temperature (T), bleaching time (t), liquor-to-goods ratio, cotton substrate (C), and water quality (W). The bleaching performance of APSs was accessed by measuring the degree of whiteness of bleached cotton fabric which was defined as the response factor for statistical anal. The screening anal. revealed that C was the most significant factor affecting the performance of APSs on bleaching of cotton fabric, followed by T, BA, [BA], pH, PS, and [H₂O₂]:[BA]. Addnl., two-factor interactions were found as well between C and T, T and pH, C and BA, C and [BA], T and [BA], W and [PS], C and PS, and pH and [H₂O₂]:[BA]. These significant main effects and two-factor interactions were interpreted in details for a better understanding of the performance of APSs on bleaching of cotton fabric. The findings of this study are valuable for further establishment and optimization of APSs for low-temperature bleaching of cotton fabric. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Reference of 10543-57-4).

N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4) belongs to amides. Because of the greater electronegativity of oxygen, the carbonyl (C=O) is a stronger dipole than the N–C dipole. The presence of a C=O dipole and, to a lesser extent a N–C dipole, allows amides to act as H-bond acceptors. Amides are not in general accessible by the direct condensation of amines with carboxylic acids for two reasons: first, both components are readily deactivated by a transfer of a proton from the acid to the amine and second, the hydroxy unit on the carbonyl of the acid is a relatively poor leaving group. Nevertheless, the formation of five- and six-membered rings is often surprisingly simple provided that other factors can be brought into play to assist in the condensation.Reference of 10543-57-4

A semi-quantitative approach for analyzing low-volatile organic compounds in house dust using an SFE method: Significant common features and particular differences of the extracts was written by Papadopoulos, Athanasios;Vlachogiannis, Diamando;Maggos, Thomas;Sfetsos, Athanasios;Karayiannis, Miltiades I.. And the article was included in Journal of Supercritical Fluids in 2013.Name: N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) This article mentions the following:

A number of samples have been collected from various indoor environments located in a semi-rural area in north-western Italy, for extraction with supercritical carbon dioxide (CO₂) and anal. of low volatility organic compounds on house dust. The investigation was based on a survey anal. approach aiming at the identification of the organic content of indoor dust. The quantification of the content of the compounds was obtained with a semi-quant. method, incorporating three pre-defined concentration ranges. The classes of compounds, mostly detected in the indoor dust samples analyzed, were fatty acids and some of their esters, n-alkanes, phthalates and alcs. Other less frequently found classes were other esters, phenols, aliphatic aldehydes and ketones. The compounds that were identified in all or in most of the house dust samples appeared predominantly in high concentration ranges while compounds detected scarcely were measured mainly in low concentrations The exptl. study verified that the most important emission sources for the organic compounds detected in the indoor environment were a wide variety of plastic materials and human activities (e.g., cooking). Particular features of some extracts were attributed to specific actions that took place in the house prior or during sampling, and/or to the materials used in the house construction or heating methods. Among the compounds identified as prominent in the house dust samples were the phthalates, of major interest with regard to their impact on human health. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Name: N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide)).

N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4) belongs to amides. The solubilities of amides and esters are roughly comparable. Typically amides are less soluble than comparable amines and carboxylic acids since these compounds can both donate and accept hydrogen bonds. Tertiary amides, with the important exception of N,N-dimethylformamide, exhibit low solubility in water. Amides can be recrystallised from large quantities of water, ethanol, ethanol/ether, aqueous ethanol, chloroform/toluene, chloroform or acetic acid. The likely impurities are the parent acids or the alkyl esters from which they have been made. The former can be removed by thorough washing with aqueous ammonia followed by recrystallisation, whereas elimination of the latter is by trituration or recrystallisation from an organic solvent.Name: N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide)

Low temperature peroxide bleaching process of milk protein fiber fabric with activation system was written by Dong, Jie;Wu, Ming-Hua;Xia, Jian-ming. And the article was included in Yinran in 2010.Electric Literature of C10H16N2O4 This article mentions the following:

To solve the yellowing problem of vinylon-milk protein fiber under conditions of high temperature and concentrated alkali, peroxide bleaching of milk protein fiber fabric was carried out with activation system of sodium nonanoyloxy benzene sulfonate, tetraacetylethylenediamine and gluconate. Optimum bleaching process was determined by orthogonal test as follows: H₂O₂/HK 15/15 g/L, alkali 0.5 g/L, bleaching at 70 °C for 70-80 min with bath ratio 1:30. Compared with traditional peroxide bleaching and sodium hydrosulfite reduction bleaching, it was indicated that the low temperature bleaching was a feasible and efficient process. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Electric Literature of C10H16N2O4).

N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4) belongs to amides. Amides include many other important biological compounds, as well as many drugs like paracetamol, penicillin and LSD. Low-molecular-weight amides, such as dimethylformamide, are common solvents. The presence of the amide group –C(=O)N– is generally easily established, at least in small molecules. It can be distinguished from nitro and cyano groups in IR spectra. Amides exhibit a moderately intense νCO band near 1650 cm−1. By 1H NMR spectroscopy, CONHR signals occur at low fields. In X-ray crystallography, the C(=O)N center together with the three immediately adjacent atoms characteristically define a plane.Electric Literature of C10H16N2O4

Exposure of 19 substances to lung A549 cells at the air liquid interface or under submerged conditions reveals high correlation between cytotoxicity in vitro and CLP classifications for acute lung toxicity was written by Gohlsch, Katrin;Mueckter, Harald;Steinritz, Dirk;Aufderheide, Michaela;Hoffmann, Sebastian;Gudermann, Thomas;Breit, Andreas. And the article was included in Toxicology Letters in 2019.Category: amides-buliding-blocks This article mentions the following:

In vivo experiments are still widely used for the testing of lung toxicity but there is an ethical and legal obligation to replace, reduce and refine animal testing. Lung A549 cells could serve as an in vitro indicator for acute lung toxicity but little data about the correlation of the cytotoxicity in A549 cells and data leading to CLP classifications are available. The authors exposed A549 cells to 19 CLP-classified substances with doses of 25, 50, and 100μg/Cm² either under submerged (SME) condition or with aerosols at the air-liquid interface (ALIF) and determined accuracy, precision, sensitivity and the F1 score with the CLP classifications H330, H332, or H335. When data from both exposure methods were combined, the authors found accuracies of 0.84, precisions of 0.74, sensitivities of 0.93 and F1 scores of 0.82. Separated from each other, ALIF exposure was more sensitive at any dose but, at higher doses, also less accurate and precise compared to SME. Considering the 19 substances tested, the authors’ data suggest that cytotoxicity in A549 cells could be a reliable in vitro indicator for in vivo toxicity. Thus, the authors discuss how A549 could be integrated into validation test guidelines. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Category: amides-buliding-blocks).

N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4) belongs to amides. Compared to amines, amides are very weak bases and do not have clearly defined acid–base properties in water. On the other hand, amides are much stronger bases than esters, aldehydes, and ketones. Amides are not in general accessible by the direct condensation of amines with carboxylic acids for two reasons: first, both components are readily deactivated by a transfer of a proton from the acid to the amine and second, the hydroxy unit on the carbonyl of the acid is a relatively poor leaving group.

Research on FTIR analysis of Populus nigra L. lignin structure changes in different bleaching processes was written by Zhao, Qiang;Sun, Dezhi;Pu, Junwen;Jin, Xiaojuan;Xing, Mian. And the article was included in Advanced Materials Research (Durnten-Zurich, Switzerland) in 2011.Reference of 10543-57-4 This article mentions the following:

To study the bleaching mechanisms of H₂O₂ bleaching, H₂O₂ displacement bleaching and H₂O₂/TAED bleaching, three kinds of lignin bleached with above processes were obtained. Three types of treated Populus nigra L lignins structure were identified and the functional groups were quantitied by FTIR. In contrast, the deacetylation and the breakage of ester bonds in H₂O₂/TAED bleaching system was much more significant. The total carbonyl group of H₂O₂ bleached lignin decreased 6.6% while displacement bleached lignin and H₂O₂/TAED bleached lignin decreased 9.2% and 15.8% resp. The PT bleaching process had stronger oxidability to destroy the syringyl units in lignin. The breakage of ether bonds and alc. hydroxyl dehydration in side chain increased after bleaching. In contrast, the stronger destroyed effect on guaiacyl dialkyl ether bond with PT bleaching processes. The conclusions obtained may interpret H₂O₂ displacement bleaching and H₂O₂/TAED bleaching systems have better bleaching efficiency than H₂O₂ bleaching system. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Reference of 10543-57-4).

Cold pad-batch pretreatment of cotton fabrics with H₂O₂/TBCC activation system was written by Liang, Xiao-ling;Hou, Ai-qin. And the article was included in Yinran in 2012.Recommanded Product: 10543-57-4 This article mentions the following:

The hydrogen peroxide/TBCC activation system is used to cold pad-batch pretreatment of cotton fabrics. The influences of the dosage of activator, hydrogen peroxide and sodium hydroxide in hydrogen peroxide/TBCC system, temperature and time on fabric whiteness, capillary effect and breaking strength are investigated and compared with hydrogen peroxide/TAED activation system. The optimized cold pad-batch pretreatment of cotton fabric is as follows: H₂O₂ (30%) 40 g/L,TBCC 4 g/L, scouring agent LFD 5 g/L, NaOH 10 g/L, Na₂SiO₃ 5 g/L, penetrating agent JFC 5 g/L, batching at 25 °C for 8 h. The effects of the hydrogen peroxide/TBCC activation system is better than those of hydrogen peroxide/TAED system. Compared with traditional process, hydrogen peroxide /TBCC process features less alkali dosage, shortened time and lower temperature in batching. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Recommanded Product: 10543-57-4).

N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4) belongs to amides. Amides can be viewed as a derivative of a carboxylic acid RC(=O)OH with the hydroxyl group –OH replaced by an amine group −NR′R″; or, equivalently, an acyl (alkanoyl) group RC(=O)− joined to an amine group. Amides can be recrystallised from large quantities of water, ethanol, ethanol/ether, aqueous ethanol, chloroform/toluene, chloroform or acetic acid. The likely impurities are the parent acids or the alkyl esters from which they have been made. The former can be removed by thorough washing with aqueous ammonia followed by recrystallisation, whereas elimination of the latter is by trituration or recrystallisation from an organic solvent.Recommanded Product: 10543-57-4

Changes in physicomechanical properties and structures of jute fibers after tetraacetylethylenediamine activated hydrogen peroxide treatment was written by Wang, Weiming;Xu, Meng;Lou, Jiahao;Dong, Aixue. And the article was included in Journal of Materials Research and Technology in 2020.Category: amides-buliding-blocks This article mentions the following:

Tetraacetylethylenediamine (TAED) activated hydrogen peroxide (H₂O₂) was tentatively used in the bleaching of scoured jute fibers, and the effects of this method on the physicomech. properties, main chem. compositions, and structures during bleaching were evaluated and compared with conventional H₂O₂ bleaching. By comparing with H₂O₂ bleached jute fibers, the TAED-activated H₂O₂ bleached jute fibers were found to have a better storage stability of whiteness and yellowness, higher breaking tenacity, lower fineness value and breaking extension. The differences in morphol. structure and thermogravimetric anal. showed that the TAED-activated H₂O₂ bleaching system had a stronger ability for the removal of noncellulosic materials than conventional H₂O₂ bleaching system. The changes in main chem. compositions and Fourier transform IR spectra further indicated that the removal ability of TAED-activated bleaching for lignin was obviously stronger than that of conventional bleaching, but it had a similar removal ability for hemicellulose. Furthermore, when the whiteness and yellowness values were similar, the amount of H₂O₂, bleaching temperature, and time of TAED-activated H₂O₂ bleaching were obviously less than those of H₂O₂ bleaching. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Category: amides-buliding-blocks).

N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4) belongs to amides. In primary and secondary amides, the presence of N–H dipoles allows amides to function as H-bond donors as well. Thus amides can participate in hydrogen bonding with water and other protic solvents; the oxygen atom can accept hydrogen bonds from water and the N–H hydrogen atoms can donate H-bonds. As a result of interactions such as these, the water solubility of amides is greater than that of corresponding hydrocarbons. These hydrogen bonds are also have an important role in the secondary structure of proteins.Category: amides-buliding-blocks

Silver Recovery from Laundry Washwater: The Role of Detergent Chemistry was written by Nawaz, Tabish;Sengupta, Sukalyan. And the article was included in ACS Sustainable Chemistry & Engineering in 2018.Synthetic Route of C10H16N2O4 This article mentions the following:

The use of Ag nanoparticles as an antimicrobial agent on textiles is rising. Ag leaching during laundry and its subsequent discharge in the environment pose ecotoxicol. risks. Removing Ag from laundry washwater is therefore an environmental necessity, but its recovery also leads to environmental sustainability. Low Ag concentration, competition from other cations (such as Ca²⁺, Mg²⁺, and Na⁺), and complexity of the detergent matrix make the recovery process challenging. This study uses a thiol-group functionalized ion-exchange resin in a fixed-bed column to remove Ag from laundry washwater and recover it as Ag₂S nanoparticles or high-purity powder. The role of each detergent component in affecting Ag speciation and the resin performance was analyzed. Builders and bleaching agents are reported to neg. impact the resin performance; pH and cocationic species (Ca²⁺) concentration are critical parameters for the successful recovery. This work demonstrates a closed-loop sustainable scheme by recycling and reusing the resin and the regenerant solution over 5 cycles. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Synthetic Route of C10H16N2O4).

Thus amides can participate in hydrogen bonding with water and other protic solvents; the oxygen atom can accept hydrogen bonds from water and the N–H hydrogen atoms can donate H-bonds. Amides are stable compounds. The lower-melting members (such as acetamide) can be readily purified by fractional distillation. Most amides are solids which have low solubilities in water.Synthetic Route of C10H16N2O4

Low temperature bleaching of cotton cheese with peroxide activator TAED was written by Shi, Wen-zhao;Xing, Jian-wei;Ren, Zhi-gang;Xu, Cheng-shu;Liu, Jin-shu. And the article was included in Yinran in 2013.Reference of 10543-57-4 This article mentions the following:

This paper aiming at the high energy consumption and fiber damage in traditional high-temperature scouring and bleaching pretreatment of cotton cheese, low-temperature pretreatment process with tetra acetyl ethylene diamine (TAED) is introduced. The effect of dosages of hydrogen peroxide and TAED, caustic soda, temperature and time on whiteness, capillary effect and tensile strength is discussed and compared with that of traditional process. The results show that the optimal process conditions are NaOH 2 g/L, H₂O₂ (30%) 6 g/L, TAED 6 g/L, treating at 60 °C for 10 min, and then holding at 80 °C for 30 min. The yams pretreated with optimal process feature higher breaking strength, similar whiteness and capillary effect, shortened process time and procedure.

Decolorization kinetics and properties of triphenodioxazine reactive dyes in sodium perborate-TAED bleaching system was written by Zhang, Jun;Zhu, Yang. And the article was included in Advanced Materials Research (Durnten-Zurich, Switzerland) in 2012.Recommanded Product: 10543-57-4 This article mentions the following:

The decolorization behaviors of a triphenodioxazine reactive dye (C.I. Reactive Blue 198) in the activated oxygen bleach system containing sodium perborate (PB) and tetra-acetylethylenediamine (TAED) were investigated. The decolorization kinetics of the dye was found to follow the first-order kinetic model and the rate constant of decolorization increased significantly with increasing temperature The activation energy for decolorizing reaction was 50.41 kJ/mol. The highest rate constant appeared at pH 8. The triphenodioxazine reactive dye showed poor stability to activated oxygen washing.
