N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4) belongs to amides. Amides can be viewed as a derivative of a carboxylic acid RC(=O)OH with the hydroxyl group –OH replaced by an amine group −NR′R″; or, equivalently, an acyl (alkanoyl) group RC(=O)− joined to an amine group. 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.Recommanded Product: 10543-57-4

Composition and application of maleate sulfonate compound neutral deinking agent was written by Ma, Xiaoyu;Li, Xiaorui;Fei, Guiqiang;Mou, Jing. And the article was included in Zhonghua Zhiye in 2010.Recommanded Product: 10543-57-4 This article mentions the following:

Neutral deinking agents were obtained by compounding maleate sulfonate ionic surfactants with two nonionic surfactants, fatty alc. polyoxyethylene ether AEO-9, AEO-3. The maleate sulfonate ionic surfactants were prepared by using maleic anhydride, polyoxyethylene alkyphenol (TX-10) and sodium sulfite. The structure of maleate sulfonate anionic surfactant and the deinking effect were investigated by FTIR and SEM. The results show that when the ratio of maleate sulfonate anionic surfactant:AEO-9:AEO-3 is at 2:1:1, the effect of neutral deinking is ideal, the whiteness of the deinking pulp can be increased above 14% ISO and the residual ink concentration can be decreased above 170 mm2/m2. 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).
