Abstract

PROCEDIMIENTO PARA LA OBTENCION DE ESTERES DEL ACIDO POLI-BAB-CIANACRILICO Y SU DEPOLIMERIZACION.CONSISTE EN HACER REACCIONAR UN FORMALDEHIDO O COMPUESTOS DISOCIADORES DE FORMALDEHIDO, CON ESTERES DE ACIDO CIANACETICO, EN PRESENCIA DE CATALIZADORES BASICOS. LA REACCION SE LLEVA A EFECTO DE FORMA CONTINUA A TEMPERATURAS COMPRENDIDAS ENTRE 50 Y 200 GRADOS Y BAJO UNA PRESION DE 1 HASTA 20 MILIBARES. LA MEZCLA DE REACCION SE ALIMENTA EN FORMA CONTINUA EN UN REACTOR, MEZCLANDOLA CON UN CATALIZADOR Y CONDUCIENDO DICHA MEZCLA A TEMPERATURA DE REACCION A TRAVES DE UNA ZONA DE REACCION, Y SEPARANDO POR DESTILACION LAS SUSTANCIAS VOLATILES.DE APLICACION COMO ADHESIVOS DE ALTA CALIDAD.
