Abstract

Un procedimiento para recuperar un fenol alquilado deseado con una pureza de al menos aproximadamente 99 % en ausencia de cristalización de aductos y sin la generación de corrientes de recirculación de la reacción, comprendiendo dicho procedimiento las etapas de: a) destilar a vacío una mezcla que comprende el fenol alquilado deseado para producir un destilado y un residuo, en el que el residuo comprende el fenol alquilado deseado y al menos un fenol alquilado no deseado; y b) someter al residuo a cristalización-fusión para obtener el fenol alquilado deseado.
