Abstract

PROCEDIMIENTO PARA LA RECUPERACION DE ACIDOS CARBOXILICOS A PARTIR DE MEZCLAS QUE CONTIENEN ESTERES DE GLICOLES DERIVADOS DE ESTOS ACIDOS. CONSISTE EN HACER REACCIONAR A EBULLICION LAS MEZCLAS QUE CONTIENEN LOS ESTERES CON AGUA, ARRASTRANDO EL ACIDO CARBOXILICO FORMADO POR MEDIO DE AGUA POR DESTILACION AZEOTROPICA. LA MEZCLA OBTENIDA SE SOMETE A UNA DESTILACION EXTRACTIVA POR MEDIO DE UN DISOLVENTE ORGANICO NO SOLUBLE EN AGUA. SE EMPLEAN MEZCLAS QUE CONTIENEN ESTERES DERIVADOS DE ACIDOS CARBOXILICOS QUE CONTIENEN DE 1 A 4 ATOMOS DE CARBONO Y GLICOLES QUE CONTIENEN 3 O 4 ATOMOS DE CARBONO. LAS MEZCLAS CONTIENEN DE 5 A 80 POR 100 EN PESO DE ESTERES.
