Abstract

PROCEDIMIENTO PARA LA OBTENCION DE CLOROFORMIATOS DE ALQUILO EN CONTINUO. CONSISTE EN LA REACCION DE LOS ALCOHOLES CORRESPONDIENTES CON FOSGENO EN EXCESO. LA REACCION SE LLEVA A CABO EN CONTRACORRIENTE A TEMPERATURAS ENTRE 0 C Y 30 C, DE MODO QUE HAYA SIEMPRE UN EXCESO DE 3-20% DE FOSGENO. LA MEZCLA DE REACCION SE DESGASIFICA EN UNA ETAPA POSTERIOR Y LOS GASES SE RETORNAN A LA REACCION DESPUES DE SEPARAR EL CLOROFORMIATO.
