Wiedemann, O. F. et al. published their research in Journal of the American Chemical Society in 1945 | 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. Industrially, the main methods for producing nitriles are ammoxidation and hydrocyanation. Both routes are green in the sense that they do not generate stoichiometric amounts of salts.Recommanded Product: 3,3′,3”-Nitrilotripropanenitrile

Some amine derivatives of acrylonitrile was written by Wiedemann, O. F.;Montgomery, W. H.. And the article was included in Journal of the American Chemical Society in 1945.Recommanded Product: 3,3′,3”-Nitrilotripropanenitrile This article mentions the following:

Correction. In C.A. 40, 832.2 the m.p. of IV is 59°, not 99°. nD25 of VI is 1.4802, not 1.4910. (CH2)2O in line 38 should read HOCH2CH2CN. In the experiment, the researchers used many compounds, for example, 3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1Recommanded Product: 3,3′,3”-Nitrilotripropanenitrile).
