Abstract

PROCESO PARA LA ELIMINACION DEL AGUA DE UNA COMBINACION DE FLUORURO DE HIDROGENO (HF), ACIDO CARBOXILICO (POR EJEMPLO, ACIDO ACETICO), Y AGUA MEDIANTE DESTILACION EXTRACTIVA CON PRESENCIA DE UNA BASE LEWIS COMO SOLVENTE, QUE NO FORME UNA MEZCLA AZEOTROPICA CON AGUA, QUE FORME ENLACES CON EL HF Y ACIDO CARBOXILICO QUE PUEDA FRACTURARSE POR CALOR Y QUE TENGA EL PUNTO DE EBULLICION A UNA PRESION ATMOSFERICA APROXIMADA DE AL MENOS 20 (GRADOS) C POR ENCIMA DE LA DEL ACIDO CARBOXILICO, POR EJEMPLO, N-METIL-2-PIRROLIDONA, ELIMINANDO EL VAPOR SALIENTE DE DESTILACION QUE CONSTA DE UNA PROPORCION PRINCIPAL DE AGUA EN DICHA COMBINACION. LA DESTILACION EXTRACTIVA PUEDE INTEGRARSE VENTAJOSAMENTE EN UN PROCESO GLOBAL CON LA PRODUCCION DE UNA CETONA AROMATICA, POR EJEMPLO, 4-HIDROXIACETOFONA, MEDIANTE ACILACION FRIEDEL-CRAFTS DE UN COMPUESTO AROMATICO (POR EJEMPLO, FENOL), CON EL ACIDO CARBOXILICO, USANDO EL HF COMO CATALIZADOR, A FIN DE OBTENER UN PRODUCTO QUE CONTENGA LA CETONA AROMATICA, EL HF, EL ACIDO CARBOXILICO Y EL AGUA, Y DE CONSEGUIR LA ELIMINACION DE LA CETONA AROMATICA DEL PRODUCTO POR MEDIO DE UNA DESTILACION A BASE DE SOLVENTE.
