Abstract

PROCEDIMIENTO PARA LA OBTENCION DE ~J,~J ICLOROVINILFOSFATO DE DIMETILO. CONSISTE EN LA REACCION DE CLORAL CON TRIMETILFOSFITO, A PRESION ATMOSFERICA. LA REACCION SE LLEVA A CABO DE MODO QUE LA TEMPERATURA DE LA MEZCLA SE MANTENGA ENTRE 60 C Y 120 C MIENTRAS SE PRODUCE LA MEZCLA DE APROXIMADAMENTE LAS DOS TERCERAS PARTES DE LOS REACTIVOS. DESPUES SE DEJA SUBIR LA TEMPERATURA HASTA 150-210 C, CON LO QUE, AL MISMO TIEMPO QUE SE COMPLETA LA REACCION, SE ELIMINAN LOS SUBPRODUCTOS. ESTE COMPUESTO TIENE APLICACIONES EN AGRICULTURA COMO INSECTICIDA.
