FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to a method for semi-hydrogenation of dinitrile of the general formula: NC-R-CN wherein R means linear or branched alkylene group comprising from 1 to 12 carbon atoms to the corresponding aminonitrile in the liquid medium. Method is carried out in the presence of a catalyst, such as nickel or Raney nickel comprising an activating element taken among rhodium or iridium wherein the weight ratio (Rh or Ir)/Ni is from 0.05% to 10%. Method provides enhancing yield of aminonitrile.
EFFECT: improved and enhanced method.
