Low-temperature activated bleaching processes and mechanism of cotton fabric was written by Wang, Kuo;Liu, Kai;Yan, Ke-lu. And the article was included in Yinran in 2017.Computed Properties of C10H16N2O4 This article mentions the following:
Low-temperature activators TAED and JML-2 are adopted for cotton bleaching, and the hydroxyl radical (OH·) in TAED/H2O2 and JML-2/H2O2 systems is detected with a novel fluorescent probe benzenepentacarboxylic acid (BA). The results show that the optimum activated bleaching condition is: 30% H2O5 g/L, NaOH 2 g/L, TAED or JML-2 3g/L, bleaching at 70°C for 60 rain. OH · yield in TAED/H2O2 system is significantly higher than that in H2O2 system. The whiteness of cotton fabric is obviously decreased when the OH · is scavenged in TAED/H2O2 system. It proves that OH · plays a significant role in TAED/H2O2 system for low-temperature bleaching. 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. 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. 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.Computed Properties of C10H16N2O4
