Gao, Jian et al. published their research in Huagong Kuangwu Yu Jiagong in 2003 | CAS: 7528-78-1

3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1) belongs to nitriles. Nitrile compounds can be prepared by the incorporation of a cyanide source through C–C bond formation or by dehydration of primary carboxamides. In conventional organic reductions, nitrile is reduced by treatment with lithium aluminium hydride to the amine. Reduction to the imine followed by hydrolysis to the aldehyde takes place in the Stephen aldehyde synthesis, which uses stannous chloride in acid.Product Details of 7528-78-1

Synthesis and characterization of bis(2-cyanoethyl)aminoacetonitrile and tris(2-cyanoethyl)amine was written by Gao, Jian;Xu, Xing-you;Tang, Yan-ling;Zhang, Xing-yang. And the article was included in Huagong Kuangwu Yu Jiagong in 2003.Product Details of 7528-78-1 This article mentions the following:

Tile compounds were prepared from addition reaction of acrylonitrile with aminoacetonitrile and aqueous ammonia resp. It was characterized by IR spectra, 1H-NMR, elemental anal., ES-MS and TG-DTA. The two compounds have similar thermal behaviors, and have high thermal stability under 300°C. In the experiment, the researchers used many compounds, for example, 3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1Product Details of 7528-78-1).
