FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to a method for synthesis of primary amine by the hydrogenation reaction of nitriles. Method involves carrying out the conversion reaction in reaction mixture that contains: (a) at least one nitrile; (b) hydrogen; (c) ammonia, if necessary, and (d) at least one cobalt or nickel catalyst modified ex situ by adsorption of alkaline metal carbonate or alkaline metal hydrocarbonate that comprises alkaline metal carbonate or hydrocarbonate taken in the amount from 2 to 12 wt.-%. Also, invention relates to a catalyst used in the method by cl. 1 and representing modified cobalt or nickel catalyst prepared by adsorption of alkaline metal carbonate or alkaline metal hydrocarbonate taken in the amount from 2 to 12 wt.-% on usual cobalt or nickel catalyst.
EFFECT: improved method of synthesis.
