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. 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. 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. 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.Recommanded Product: 10543-57-4
