FIELD: chemical industry. SUBSTANCE: claimed invention describes process for hydrocyanation of nitriles having ethylene unsaturation to saturated dinitriles, especially hydrocyanation of pentene nitriles to adiponitriles, one of the main compounds for preparing polyamide-66. Claimed process of hydrocyanation of aliphatic nitrile having ethylene unsaturation by reacting with cyanohydrogen in the presence of aqueous catalyst solution containing transition metal compound and sulfonated phosphine. The above mentioned solution also contains cocatalyst consisting of at least one of Lewis acid. EFFECT: more efficient preparation process. |
