Zusammenfassung:1,193,732. N,N - Bis - (aminopropyl) and (cyanoethyl) amides. FARBENFABRIKEN BAYER A.G. 15 March, 1968 [20 March, 1967], No. 12660/68. Heading C2C. [Also in Divisions B2 and C3] may be prepared by reacting di-(2-cyanoethyl)- amine with succinic anhydride to form succinic acid N-di-(2-cyanoethyl)amide which is isolated, converted to the sodium salt by addition of NaOH and the sodium salt catalytically hydrogenated in the presence of Raney cobalt. may be prepared by reacting di-(2-cyanoethyl)- amine with phthalic acid anhydride to form phthalic acid N- (2-cyanoethyl)amide which is isolated, converted to the sodium salt by addition of NaOH and the sodium salt catalytically hydrogenated in the presence of Raney cobalt.
