Low temperature bleaching of wool tops was written by Hu, Xiao-lin;Ren, Da-yong;Dong, Ling. And the article was included in Yinran in 2014.Formula: C10H16N2O4 This article mentions the following:
The low-temperature active bleaching system of H2O2/TAED (tetra acetyl ethylene diamine) is applied to wool tops and its results are compared with those of the traditional bleaching process. The optimum low-temperature bleaching process is H2O2/TAED molar ratio 1:0.5, 30% H2O2 8-10 mL/L, bleaching stabilizer 2 g/L, JFC 2 g/L, and liquor ratio 1:100 without adjusting the pH value, bleaching at 50°C for 20-30 min. The better effects of bleaching and dyeing, and less strength loss are obtained. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Formula: 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 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.Formula: C10H16N2O4
