N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4) belongs to amides. Because of the greater electronegativity of oxygen, the carbonyl (C=O) is a stronger dipole than the N–C dipole. The presence of a C=O dipole and, to a lesser extent a N–C dipole, allows amides to act as H-bond acceptors. Amides can be recrystallised from large quantities of water, ethanol, ethanol/ether, aqueous ethanol, chloroform/toluene, chloroform or acetic acid. The likely impurities are the parent acids or the alkyl esters from which they have been made. The former can be removed by thorough washing with aqueous ammonia followed by recrystallisation, whereas elimination of the latter is by trituration or recrystallisation from an organic solvent.Synthetic Route of C10H16N2O4

Investigation of a homogeneous activating ozonation method in the rinsing procedure of cotton fabric dyed with reactive dye [Erratum to document cited in CA155:354636] was written by Mao, Ya-Hong;Guan, Yu;Luo, Deng-Hong;Zheng, Qing-Kang;Feng, Xi-Ning;Wang, Xiu-Xing. And the article was included in Coloration Technology in 2011.Synthetic Route of C10H16N2O4 This article mentions the following:

On page 265, in Table 7, in row 2, in column 4, the Peak II chem. formula, “C4H6ozone”, was incorrectly given, and should read: “C4H6O3“. The correct version of the table is given. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Synthetic Route of C10H16N2O4).
