Reinforcement of hydrogen peroxide bleaching of bamboo pulp was written by Li, Peiyi;Zhang, Meiyun;Xia, Xinxing;Lin, Chuntao. And the article was included in Advanced Materials Research (Durnten-Zurich, Switzerland) in 2012.Application In Synthesis of N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) This article mentions the following:

Magnesium-based alkalis and the Chelants (tetra acetyl ethylene diamine (TAED), Sodium Citrate and Opal) for hydrogen peroxide bleaching of bamboo pulp were investigated in this paper. The results showed that the optimal conditions of hydrogen peroxide bleaching of bamboo pulp were as follows: H₂O₂ 4%, Mg(OH)₂:NaOH=25%, Sodium Citrate 1%, Opal 1.5%, TAED:H₂O₂=0.67, temperature 60°C, and time 90 min. Under the optimum conditions, the brightness of bamboo pulp can be enhanced from 41.2% ISO to 78.2% ISO, while the brightness of bleached pulp by using the Mg(OH)₂-based alkalis was higher than by using NaOH as the alkali source. It can be seen that Sodium Citrate, Opal, and TAED activated H₂O₂ bleaching needed lower reaction temperature, shorter time, and got better brightness and alleviated environment pollution, compared with the conventional H₂O₂ bleaching of the same pulp. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Application In Synthesis of 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. 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 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.Application In Synthesis of N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide)

Experimental evaluation of the effect of particle properties on the segregation of ternary powder mixtures was written by Asachi, Maryam;Hassanpour, Ali;Ghadiri, Mojtaba;Bayly, Andrew. And the article was included in Powder Technology in 2018.Application of 10543-57-4 This article mentions the following:

Segregation of components, especially the low content level of a highly active substance, has serious deleterious effects on powder formulation. This study investigates the effect of particle properties, particularly size, shape, d. and cohesion, on the segregation of laundry detergent powders. Tetraacetylethylenediamine (TAED) particles, spray-dried synthetic detergent powder referred to as Blown Powder (BP) and Enzyme Placebo Granules (EP granules) are used as a model formulation. The segregation of components is evaluated using image processing of the photog. records taken from the front face of a two-dimensional heap of powders. Coefficient of variation concept is considered as segregation index. It is shown that EP granules, the component used as low-level ingredient (< 2 wt%) in the ternary mixture, are prone to extensive segregation due to their higher d. as compared to BP and TAED particles. Desired properties for segregation minimisation of EP granules have been further investigated. It is found that the segregation of EP granules can be reduced noticeably by applying a thin layer of a sticky liquid on them before mixing with the rest of powders with full particle size distribution of the components. Polyethylene glycol has been used for this purpose. Addition of 2.5 wt% gives an optimum level to reduce the segregation of EP granules without compromising the flowability of the mixture as well as EP granules themselves. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Application 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.Application of 10543-57-4

Actual contamination of the Danube and Sava Rivers at Belgrade (2013) was written by Antonijevic, Milan D.;Arsovic, Marija;Caslavsky, Josef;Cvetkovic, Vesna;Dabic, Predrag;Franko, Mladen;Ilic, Gordana;Ivanovic, Milena;Ivanovic, Nevena;Kosovac, Milica;Medic, Dragana;Najdanovic, Slobodan;Nikolic, Milica;Novakovic, Jovana;Radovanovic, Tatjana;Ranic, Durdina;Sajatovic, Dojan;Spijunovic, Gorica;Stankov, Ivana;Tosovic, Jelena;Trebse, Polonca;Vasiljevic, Olivera;Schwarzbauer, Jan. And the article was included in Journal of the Serbian Chemical Society in 2014.Application In Synthesis of N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) This article mentions the following:

This study was focussed on a comprehensive investigation on the state of pollution of the Danube and Sava Rivers in the region of Belgrade. Different complementary anal. approaches were employed covering both i) organic contaminants in the river water by target analyses of hormones and neonicotinoids as well as non-target screening analyses and ii) heavy metals in the sediments. Finally, some common water quality parameters were analyzed. The overall state of pollution is on a moderate level. Bulk parameters did not reveal any unusual observations. Moreover, quantification of preselected organic contaminants did not indicate to elevated pollution. More significant contaminations were registered for chromium, nickel, zinc and partially copper in sediments with values above the target values according to Serbian regulations. Lastly, non-target screening anal. revealed a wider spectrum of organic contaminants comprising pharmaceuticals, tech. additives, personal care products and pesticides. The study presented a comprehensive view on the state of pollution of the Sava and Danube Rivers and is the base for setting up further monitoring programs. As a superior outcome, it was illustrated how different chem. analyses can result in different assessments of the river quality. A comparison of target and non-target analyses pointed to potential misinter-pretation of the real state of pollution. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Application In Synthesis of 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 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. 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.Application In Synthesis of N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide)

Low-temperature bleaching of cotton induced by glucose oxidase enzymes and hydrogen peroxide activators was written by Tavccer, Petra Forte. And the article was included in Biocatalysis and Biotransformation in 2012.Computed Properties of C10H16N2O4 This article mentions the following:

Glucose oxidase enzymes were used to produce hydrogen peroxide from glucose and oxygen in aqueous solutions Different working conditions, i.e., temperature, aeration with liquefied air, presence of cotton fiber and time of enzyme activity, were tested in order to obtain a solution with the highest possible concentration of hydrogen peroxide. The hydrogen peroxide produced was transformed into different peracids which could bleach the cotton fabric under mild conditions, at a pH between 7 and 8 and at a temperature of around 60°C. The conversion or activation of hydrogen peroxide was conducted with the bleach activators TAED, NOBS and TBBC. The concentrations of hydrogen peroxide and peracids in the solutions were measured with sodium thiosulfate titrations The results indicated that the formation of hydrogen peroxide with glucose oxidase was effective under optimal conditions, which are 50°C, pH 4.6 and aeration. Convenient activators for the conversion of hydrogen peroxide into peracids were TAED and TBBC, which enabled attainment of a relatively high degree of whiteness at pH 7.5 and temperature 50°C. Using the activator NOBS under these conditions did not provide enough peracid to markedly improve whiteness. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Computed Properties of C10H16N2O4).

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. Amides can be freed from solvent or water by drying below their melting points. These purifications can also be used for sulfonamides and acid hydrazides.Computed Properties of C10H16N2O4
