Abstract

LA INVENCION SE REFIERE A UN PROCESO MEJORADO PARA PREPARAR ACIDOS GRASOS A PARTIR DE ALQUIL, PREFERIBLEMENTE ESTERES DE METIL POR MEDIO DE HIDROLISIS ACIDA UTILIZANDO PROPORCIONES DE AGUA/ESTER/CATALIZADOR ACIDO PARA FORMAR MEZCLAS DE REACCION DE FASE SIMPLE EN DONDE LA RELACION ESTOIQUIOMETRICA INICIAL DE AGUA CON RELACION AL ESTER ES DE ALREDEDOR 1:1. ESTAS PROPORCIONES SE REPRESENTAN POR EL DIAGRAMA DE FASE TERNARIA DE LA FIG. 1 PARA UN CATALIZADOR DE ACIDO SULFONICO DE ALQUILBENCENO C6-C14 ADECUADO QUE TENGA UNA UNION DE PUNTO MEDIO DE LA CADENA DE ALQUIL CON EL ANILLO DE BENCENO.
