Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA OBTENER CARBOIMIDA ORGANICA A TRAVES DE CARBOIMIDACION DE GRUPOS ISOCIANATOS CON CATALIZADORES DEL TIPO FOSFOLINA, QUE SE CARACTERIZA YA QUE AL TERMINO DE LA REACCION DE CARBOIMIDACION SE SEPARA EL CATALIZADOR A TRAVES DE LA INTRODUCCION DE DIOXIDO DE CARBONO A UNA TEMPERATURA A 100 A 250 C EN VACIO.
