Abstract

Procedimiento para la preparación de succionitrilo por reacción de acrilonitrilo con ácido cianhídrico en presencia de un catalizador alcalino, caracterizado por emplear como catalizador trietilamina en una cantidad de por lo menos el 2 por ciento en peso, calculada con respecto a la mezcla de reacción global, y porque la reacción se efectúa con un exceso de acrilonitrilo a una temperatura inferior a 90ºC.
