Abstract

SE HA DESCUBIERTO UN PROCEDIMIENTO PARA SEPARAR EL AGUA DE MEZCLAS DE REACCION DE ACIDOS O ANHIDRIDOS DE ACIDOS O DE SOLUCIONES ACUOSAS HIDROXIDAS DE METALES ALCALINOS CON ALCOHOLES, APLICANDO PERMEACION DE VAPOR/PERVAPORACION A LA TEMPERATURA DE EBULLICION DE LA MEZCLA DE REACCION. ESTE PROCEDIMIENTO SE CARACTERIZA PORQUE EL EDUCTO CON EL PUNTO DE EBULLICION MAS BAJO ES PRESENTADO, EN CADA CASO EN LO QUE RESPECTA AL OTRO EDUCTO, ESTEQUIOMETRICAMENTE JUNTO CON ESTE OTRO EDUCTO, PORQUE LA MEZCLA DE REACCION ES CALENTADA HASTA QUE ENTRA EN EBULLICION, DESPUES DE LO CUAL LA MEZCLA DE VAPOR PRODUCIDA DE LA MEZCLA DE REACCION EN EBULLICION ES DESHIDRATADA EN SU MAYOR PARTE DE AGUA Y DE COMPONENTES CON EL PUNTO DE EBULLICION MAS BAJO EN UNA MEMBRANA, CONDUCIENDOSE LA MEZCLA DE VAPOR DESHIDRATADA NUEVAMENTE A LA MEZCLA DE REACCION Y AÑADIENDOSE DURANTE LA REACCION A LA MEZCLA DE REACCION EL EDUCTO CON EL PUNTO DE EBULLICION MAS BAJO.
