Abstract

SE DESCRIBE UN PROCESO PARA LA PRODUCCION DE LA CICLOPROPILMETILCETONA INTERMEDIA CONOCIDA QUE SUMINISTRA POCOS PRODUCTOS SECUNDARIOS, DE ALTO RENDIMIENTO, UNA GRAN EFICIENCIA ANTE LA REACCION Y UTILIZACION Y ES MAS VIABLE TANTO PRACTICA COMO COMERCIALMENTE. ANTE LA PRESENCIA DE UN EXCESO DE UN HALURO METALICO O DE UN HALURO DE FOSFONIO CUATERNARIO DEL GRUPO I O DEL GRUPO II DE LA TABLA PERIODICA, LA O-ACETIL-GAMMA-BUTIROLACTONA ES CONDUCIDA CONTINUAMENTE A UN RECIPIENTE DE REACCION A 170200 (GRADOS) C Y LA CICLOPROPILMETILCETONA SE DESTILA CONTINUAMENTE. EL HALURO SE RECUPERA Y SE RECICLA EN EL PROCESO.
