organic chemistry. SUBSTANCE: described is method of preparing aliphatic alpha and omega aminonitriles by partial hydrogenation of aliphatic alpha and omega dinitriles at higher temperature and elevated pressure in the presence of hydrogenation catalyst, ammonia solvent and lithium hydroxide or compound from which hydroxide is formed during hydrogenation. Said method makes it possible to make process more economical due to increased yield and greater selectivity. EFFECT: more efficient preparation method. 4 cl, 1 ex, 2 tbl
