Synergistic action of homogeneous activator tetraacetylethylenediamine (TAED) on ozone decolorization of reactive dyes was studied. Influences of ozone airflow, TAED concentration, pH value and reaction time on decoloration rate and CODCr value were investigated. The results showed that activator TAED could enhance ozone decolorization action, improve decoloration rate and removal of CODCr shorten reaction time by activating ozone to produce peracetic acid and reduce surface tension of the solution 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. 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. 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.COA of Formula: C10H16N2O4
