Abstract

PROCEDIMIENTO PARA SEPARAR UN DIENO CONJUGAO DE UNA MEZCLA DE HIDROCARBUROS QUE CONTIENEN EL CITADO DIENO CONJUGADO, MEDIANTE DESTILACION EXTRACTIVA A ALTA TEMPERATURA, USANDO DIMETILFORMAMIDA COMO DISOLVENTE DE EXTRACCION. CONSISTE EN INHIBIR LA POLIMERIZACION DEL CITADO DIENO CONJUGADO EN DIMETILFORMAMIDA A ALTA TEMPERATURA, MEDIANTE LA ADICION DE FURFURAL Y PRODUCTOS DE POLICONDENSACION, CONTROLANDO LAS CANTIDADES DE DICHOS INHIBIDORES DE POLIMERIZACION DE TAL MODO QUE ESTEN PRESENTES EN UN 0,01 A UN 2% EN PESO DE FURFURAL Y EN UN 0,5 A UN 10% EN PESO DE PRODUCTOS DE POLICONDENSACION DE FURFURAL, REFERIDOS AL PESO EN TANTO POR CIENTO DEL DISOLVENTE, CUMPLIENDOSE ADEMAS QUE LA CANTIDAD TOTAL DE FURFURAL Y PRODUCTOS DE POLICONDENSACION DE FURFURAL, REFERIDOS AL PESO EN TANTO POR CIENTO DEL DISOLVENTE, CUMPLIENDOSE ADEMAS QUE LA CANTIDAD TOTAL DE FURFURAL Y PRODUCTOS DE POLICONDENSACION DE FURFURAL ESTE COMPRENDIDA ENTRE 1 Y UN 12% EN PESO, MIENTRAS DURE EL PROCESO DE SEPARACION DEL DINEROCONJUGADO. DE USO EN LA SEPARACION DE BUTADIENO, ISOPRENO Y 1,3-PENTADIENO DE UNA MEZCLA DE HIDROCARBUROS QUE LOS COTIENEN.
