Abstract
Authors studied on the synthesis of bis- (β-cyanoethyl) -alkyl amine in cyanoethylation of methyl amine.
As well in the previous report, the reactivity of cyanoethylation in polar or non-polar solvent was investigated.
As a result, consequently, authors obtained the following conclusion.
As compared with fatty amines of C6, C9 and C16 the methyl amine was easier to form bis- (β-cyanoethyl) -alkyl amine. Under the condittion, using methyl amine saturated in methanol or water solvent and three moles of acrylonitrile per mole of amine at reaction temperature of, 70°C for 6 hr reaction timeor at 20°C for 24 hrs, bis- (β-cyanoethyl) -methyl amine was obtained in almost stoichiometric quantity.
As compared with I.N. Nazarov's method achieving the maximum yield in many literatures hitherto reported, the authors' method above mentioned is much easier in the operation and the yield of biscyanoethylate is higher than that.
