Abstract

LA DOTACION DIRECTA DE SOLUCIONES ACUOSAS CON ACROLEINA COMO MICROBICIDA ES PROBLEMATICA DEBIDO A LAS COSTOSAS MEDIDAS DE SEGURIDAD QUE CONLLEVA, Y LA APLICACION CONOCIDA HASTA AHORA DE MEZCLAS DE REACCION DE LA DESACETALIZACION HA DEMOSTRADO SER POCO RENTABLE. DE ACUERDO A LA INVENCION, LAS SOLUCIONES ACUOSAS PUEDEN SER DOTADAS DE MANERA SENCILLA, SEGURA Y RENTABLE CON ACROLEINA EN CONCENTRACION BIOCIDA ACTIVA, SIEMPRE QUE SE DISOCIEN ACETALES DE ACROLEINA EN FASE ACUOSA EN PRESENCIA DE UN CATALIZADOR DE DESACETALIZACION MUY ACIDO Y SE DISOCIEN LOS COMPONENTES DE ALCOHOL, Y LA ACROLEINA FORMADA SE ELIMINE CONTINUAMENTE DE LA MEZCLA DE DESACETALIZACION, Y MEDIANTE UNA CORRIENTE DE GAS INERTE O MEDIANTE UNA BOMBA DE INYECCION DE LIQUIDO SE TRANSPORTE LA SOLUCION ACUOSA A DOTAR COMO UN LIQUIDO DE INYECCION A LA SOLUCION ACUOSA A DOTAR.
