Characterization and biological studies of bis- and tera-acetyl derivatives of hydrocarbon-bridged diamines-I was written by Haque, Naheed;Hussain, Izhar. And the article was included in Pakistan Journal of Pharmaceutical Sciences in 2013.Recommanded Product: N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) This article mentions the following:

A systematic study of the pharmaceutically important, double ended, chelating agents of the types CH₃CONH(CH₂)_nNHCOCH₃ and (CH₃CO)₂N(CH₂)_n N(COCH₃)₂, where n = 2, 3, 4, 5 and 6, prepared by the bis- and tetra-acetylation of the corresponding diamino-polymethylenes, have been carried out. Bis- and tetra-acetyl derivatives have been characterized by their elemental anal. and the FTIR spectra, Mass spectra and ¹H NMR spectra of these compounds have been reported to establish their structures. In the present work, FTIR spectra have been found an excellent means for distinguishing the bis-acetyl derivatives from their tetra-acetyl counterparts. The structures of these bis- and tetra-acetyl compounds have further been established by their ¹H NMR and Mass Spectra. The selective pharmacol. screening of the derivatives was carried out according to the standard procedures. The compounds were screened for their antibacterial and antifungal activities and it was found that majority of these compounds did not possess any remarkable activity. Only the compound BA1,2-DAE, showed significant antifungal activity against Microsporum canis (80%). In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Recommanded Product: 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. Amides are pervasive in nature and technology. Proteins and important plastics like Nylons, Aramid, Twaron, and Kevlar are polymers whose units are connected by amide groups (polyamides); these linkages are easily formed, confer structural rigidity, and resist hydrolysis. Ionic, or saltlike, amides are strongly alkaline compounds ordinarily made by treating ammonia, an amine, or a covalent amide with a reactive metal such as sodium.Recommanded Product: N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide)

Use of product and ingredient tools to assess the environmental profile of automatic dishwashing detergents was written by Van Hoof, Gert;Fan, Ming;Lievens, Alain. And the article was included in Journal of Cleaner Production in 2017.COA of Formula: C10H16N2O4 This article mentions the following:

Sustainable use of resources is gaining more attention as demonstrated into recent policy goals by the United Nations and the European Union and becomes an integral part of many corporate sustainability visions. The case study shows the more efficient use of materials in P&G automatic dishwashing detergents (ADD) placed on the market in Europe, Middle East and Africa (EMEA) by replacing sodium tripolyphosphate (STPP) with Me glycine diacetic acid (MGDA). The use of phosphates in ADD in the European Union will be restricted as of 2017. This study is innovative as it combines several tools in a complementary way to enable data based decision making. Life Cycle Assessment (LCA) consistent with ISO 14040/44 standards compares environmental impacts for two ADD unit dose products (i.e. with and without STPP). Different assessment tools were used to evaluate the freshwater aquatic toxicity profile: the Critical Dilution Volume (CDV), USEtox, environmental risk assessment and the Environmental Safety Check (ESC). For the relevant LCA indicators, a significant reduction (i.e. > 10%) is observed on ADD products without phosphate vs. the phosphate containing product. CDV and USEtox scores on the down the drain emissions from the new product are reduced by 30% and 22% resp. as compared to the phosphate containing formula. Overall, no major trade-offs are observed with the replacement of STPP by MGDA. Benefits are due to a 20% reduction of the mass of ingredients per dose with the new product and the replacement of STPP by MGDA. The ESC evaluation and environmental risk assessment for MGDA show that a low environmental risk is expected per its favorable environmental fate and ecotoxicol. profiles. Based on the proven safety profile of MGDA, the reductions in LCA indicators and absence of trade-offs, it can be concluded that the new product has an improved environmental profile. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4COA of Formula: C10H16N2O4).

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. In simple aromatic amides, fragmentation occurs on both sides of the carbonyl group. If a hydrogen is available in N-substituted aromatic amides, it tends to migrate and form an aromatic amine and the loss of a ketene.COA of Formula: C10H16N2O4

The application effect of four hydrogen peroxide activators in enzyme one bath pretreatment was investigated. The results showed that the effect of TAED was good. Enzyme peroxide one bath could reduce the alkali dosage and reduce the burden on sewage treatment. The application process was as follows: gray fabric padding the first working fluid (two-dip-two-nip, padding rate 90% ∼ 100%, the working fluid temperature 50 ∼ 55 °C) → curled batching (50 °C,12 h) → padding the second working fluid (two-dip-two-nip, padding rate 90% ∼ 100%, the working fluid temperature 40 °C) → steaming (80 °C,10 min) → washing → drying. The first working fluid: KDN scouring enzyme 2 g/L, low temperature scouring penetrant GR-01 10 g/L, hydrogen peroxide solution 36 mL/L, activator 18 g/L, pH = 8. The second working fluid: low temperature scouring penetrant GR-01 10 g/L, hydrogen peroxide solution 44 mL/L, activator 22 g/L, pH = 8 ∼ 9.

Application of TAED/H₂O₂ system for low temperature bleaching of crude cellulose extracted from jute fiber was written by Wen, Zuoqiang;Zou, Linbo;Wang, Weiming. And the article was included in IOP Conference Series: Materials Science and Engineering in 2018.Category: amides-buliding-blocks This article mentions the following:

Tetraacetylethylenediamine (TAED) activated hydrogen peroxide system had been applied for bleaching of crude cellulose extracted from jute fiber. Comparing with conventional hydrogen peroxide bleaching system, those results showed that bleaching temperature and time could be effectively reduced, and a preferable whiteness could be produced under faint alk. condition. And the optimum conditions for activated bleaching system could be summarized as molar ratio of H₂O₂/TAED 1:0.7, pH 8, pure hydrogen peroxide 0.09 mol/L, temperature 70°C and time 60min. 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. 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. Ionic, or saltlike, amides are strongly alkaline compounds ordinarily made by treating ammonia, an amine, or a covalent amide with a reactive metal such as sodium.Category: amides-buliding-blocks

Mechanism of H₂O₂/bleach activators and related factors was written by Liu, Kai;Yan, Kelu;Sun, Gang. And the article was included in Cellulose (Dordrecht, Netherlands) in 2019.HPLC of Formula: 10543-57-4 This article mentions the following:

Abstract: A mechanism of H₂O₂/bleach activator bleaching systems was proposed by using H₂O₂/tetraacetylethylenediamine (TAED) system as a model. HO· concentrations of the system under different pH conditions was measured by using benzenepentacarboxylic acid as a fluorescent probe. Computational anal. of bond enthalpies of H₂O₂ and peracids revealed that HO· should be the most effective agent in bleaching process, and peracids formed in H2O2/bleach activator bleaching systems could more easily produce HO^·. The formation of peracids in H₂O₂/TAED system depends on the pH values of bleaching solutions and a nucleophilic substitution of the acid derivative by peroxide anion (HOO^–). Charge d. on carbonyl carbons of bleach activators affects the formation of peracids as well, which was proven from these compounds of TAED, tetraacetylhydrazine, N-[4-(triethylammoniomethyl)-benzoyl]-caprolactam chloride, phthalimide, N-acetylphthalimide and nonanoyloxybenzene sulfonate. It is likely that the charge densities on carbonyl carbon of amide bleach activators should be larger than 0.185. For ester bleach activators, the results were also investigated by activation energy, Gibbs free energy and Hansen solubility parameters. In addition, the ecotoxicity of bleach activators has been evaluated by ECOSAR program. Potential bleach activators can be designed and explored according to these results instead of large amounts of exptl. data. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4HPLC of Formula: 10543-57-4).

For the purpose of improving the control of the hydrogen peroxide decomposition rate, the prediction of the bleaching results, and the optimization of cotton fabric bleaching process, a self-made cationic gelatin protein agent was used in cotton hydrogen peroxide bleaching and hydrogen peroxide decomposition rate was calculated The influence of self-made cationic gelatin protein agent, stabilizing agent sodium silicate and activator TAED on the hydrogen peroxide decomposition rate was compared. The results showed that cationic gelatin protein could promote the decomposition of hydrogen peroxide effectively and the decomposition rate was closed to TAED under low temperature and low alkali. The cationic gelatin protein acted as an activator in bleaching process. It provided a theor. basis for the cationic gelatin protein agent application in hydrogen peroxide bleaching with low temperature and low alkali.

Composition and application of maleate sulfonate compound neutral deinking agent was written by Ma, Xiaoyu;Li, Xiaorui;Fei, Guiqiang;Mou, Jing. And the article was included in Zhonghua Zhiye in 2010.Recommanded Product: 10543-57-4 This article mentions the following:

Neutral deinking agents were obtained by compounding maleate sulfonate ionic surfactants with two nonionic surfactants, fatty alc. polyoxyethylene ether AEO-9, AEO-3. The maleate sulfonate ionic surfactants were prepared by using maleic anhydride, polyoxyethylene alkyphenol (TX-10) and sodium sulfite. The structure of maleate sulfonate anionic surfactant and the deinking effect were investigated by FTIR and SEM. The results show that when the ratio of maleate sulfonate anionic surfactant:AEO-9:AEO-3 is at 2:1:1, the effect of neutral deinking is ideal, the whiteness of the deinking pulp can be increased above 14% ISO and the residual ink concentration can be decreased above 170 mm²/m².

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

And the article was included in International Journal of Biological Macromolecules in 2019.Related Products of 10543-57-4 This article mentions the following:

A new manganese peroxidase-producing white-rot basidiomycete fungus was isolated from symptomatic wood of the camphor trees Cinnamomum camphora (L.) at the Hamma Botanical Garden (Algeria) and identified as Trametes pubescens strain i8. The enzyme was purified (MnP TP55) to apparent electrophoretic homogeneity and biochem. characterized. The specific activity and Reinheitzahl value of the purified enzyme were 221 U/mg and 2.25, resp. MALDI-TOF/MS anal. revealed that the purified enzyme was a monomer with a mol. mass of 55.2 kDa. The NH₂-terminal sequence of the first 26 amino acid residues of MnP TP55 showed high similarity with those of white-rot fungal peroxidases. It revealed optimal activity at pH 5 and 40 °C. This peroxidase was completely inhibited by sodium azide and potassium cyanide, suggesting the presence of heme-components in its tertiary structure. Interestingly, MnP TP55 showed higher catalytic efficiency, organic solvent-tolerance, dye-decolorization ability, and detergent-compatibility than that of horseradish peroxidase (HRP) from roots of Armoracia rustanica, manganese peroxidase from Bjerkandera adusta strain CX-9 (MnP BA30), and manganese peroxidase from Phanerochaete chrysosporium (MnP PC). Overall, the findings provide strong support for the potential candidacy of MnP TP55 for environmental applications, mainly the development of enzyme-based technologies for lignin biodegradation, textile-dyes biodecolorization, and detergent formulations. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Related Products of 10543-57-4).

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.Related Products of 10543-57-4

Multi stage peroxide and activated peroxide bleaching of kenaf bast pulp was written by Zeinaly, Farhad;Shakhes, Jalal;Zeinali, Nooshin. And the article was included in Carbohydrate Polymers in 2013.Safety of N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) This article mentions the following:

Soda-anthraquinone kenaf bast pulp (12.5 kappa number and 32% ISO brightness) has been bleached with multi stage peroxide bleaching process. Bleaching process was carried out in different sequences of peroxide stage without and with activator (tetraacetylethylenediamine, TAED) to about 80% ISO brightness. Full bleached pulp production with high brightness and viscosity and also, low COD and no adsorbable organic halogens (AOX) in effluent are the aims of this study. The effects of temperature, retention time, chem. charges, TAED/peroxide ratio and alkalinity have been studied in order to maximize the brightness gain at the lowest viscosity loss. H₂O₂ was activated as bleaching agent under milder conditions, such as low alkalinity or low temperature, by TAED activator. Therefore, TAED charge caused to an improvement in viscosity, pulp yield and effluent COD load. Pre-treatment with EDTA for 30 min and in acidic condition gave 2-4% gain in ISO brightness. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Safety of N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide)).
