Abstract

PROCEDIMIENTO PARA LA TRANSFORMACION DE UN GRUPO ACIDO CARBOXILICO, SITUADO EN EL ANILLO DE UN COMPUESTO HETROAROMATICO ARILICO O NITROGENADO, EN UN GRUPO TRICLOROMETILO. CONSISTE EN LA REACCION DE UN COMPUESTO HETROAROMATICO ARILICO O NITROGENADO CON UN DICLORURO DE FENILFOSFONIO Y PENTACLORURO DE FORFORO, POR CALENTAMIENTO A REFLUJO A TEMPERATURAS ENTRE 100 Y 250 GRADOS CENTIGRADOS Y A AL PRESION ATMOSFERICA. SE ENFRIA LA MEZCLA DE REACCION, SE SEPARA EL OXICLORURO DE FOSFORO FORMADO POR DESTILACION A PRESION REDUCIDA, Y EL PRODUCTO OBTENIDO SE SEPARA Y PURIFICA SIGUIENDO METODOS CONVENCIONALES.
