Bleaching of modal/AN-g-casein fiber blend with H2O2/TAED activating system was written by Li, Qing;Tang, Hui;Tang, Ren-Cheng. And the article was included in Journal of Applied Polymer Science in 2012.COA of Formula: C10H16N2O4 This article mentions the following:
The bleaching of modal/AN-g-casein fiber blend using hydrogen peroxide/tetraacetylethylenediamine (H2O2/TAED) activating system was investigated, and the influence of key factors on bleaching was determined The whiteness index of bleached fabrics was greatly affected by sodium carbonate and H2O2/TAED dosages, and the dyeability of bleached fabrics with acid dyes was greatly dependent on H2O2/TAED dosages and bleaching temperature Compared with the conventional H2O2 bleach under alk. conditions, the activated bleach markedly decreased the loss of casein in AN-g-casein fiber due to its acidic conditions, and exhibited the advantages of energy saving and high efficiency. However, the fabrics bleached using the activated process had the poor acidic dyeing properties due to the oxidation of amino groups in AN-g-casein fiber. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012. 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. 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 can be freed from solvent or water by drying below their melting points. These purifications can also be used for sulfonamides and acid hydrazides.COA of Formula: C10H16N2O4
