Abstract

A process for the preparation of colour-stable levulinic acid by hydrolysis of acetyl succinates using aqueous mineral acids, where the starting materials are treated continuously with steam in countercurrent in a reactor cascade, the reaction being carried out at above the boiling point of the alcohol produced during the reaction or above the boiling point of the aqueous azeotrope produced.
