METHOD FOR STABILIZATION OF UNPURIFIED ACETONITRILE AND METHOD FOR PRODUCTION OF HYDROGEN CYANIDE Russian patent published in 1998 - IPC

Abstract RU 2113430 C1

FIELD: production of hydrogen cyanide. SUBSTANCE: method involves co-operative mixing of unpurified acetonitrile with strong base and with aldehyde. Then thus prepared mixture is heated to its spraying temperature to stabilize unpurified acetonitrile. The process is followed by extraction of stabilized acetonitrile. EFFECT: improved efficiency of the method. 11 cl
