Abstract

PERFECCIONAMIENTOS INTRODUCIDOS EN UN PROCEDIMIENTO DE OBTENCION DE DERIVADOS DE ACIDO ACETICO, TALES COMO, GLICINA, IDA Y NTA POR DESHIDROGENACION DE MONO-, DI- Y TRIETANOLAMINA, RESPECTIVAMENTE, EN PRESENCIA DE UN CATALIZADOR DE COBRE-RANEY. LOS PERFECCIONAMIENTOS CONSISTEN EN REGENERAR EL CATALIZADOR UTILIZADO PARA PODER REUTILIZARLO EN SUCESIVOS CICLOS DE REACCION. EL PROCESO DE REGENERACION CONSISTE EN TRATAR EL CATALIZADOR USADO CON ACIDO FORMICO A REFLUJO, FILTRARLO Y REPULPARLO CON AGUA DESMINERALIZADA Y SOSA HASTA QUE LAS AGUAS DE LAVADO ALCANCEN UN VALOR LIGERAMENTE ALCALINO. MERCED A ESTE PROCESO DE REGENERACION DEL CATALIZADOR EL PROCEDIMIENTO DE OBRTENCION DE LOS DERIVADOS DE ACIDO ACETICO ES ECONOMICA E INDUSTRIALMENTE VIABLE. EL CATALIZADOR REGENERADO PUEDE SER REUTILIZADO EN SUCESIVOS CICLOS DE REACCION MANTENIENDO UN RENDIMIENTO MEDIO DEL 87%, ESTO ES, DEL MISMO ORDEN DE MAGNITUD QUE CUANDO SE UTILIZA CATALIZADOR NUEVO.
