Abstract:
A process for the isolation of levulinic acid including the following steps: a. performing acid catalyzed hydrolysis of a C6 carbohydrate-containing feedstock to obtain reaction product X, b. purifying of reaction product X to provide a composition  1,  comprising at least 75 wt. % levulinic acid, at most 15 wt. % solvent and at most 10 wt. % impurities, based on the total weight of composition  1,  c. feeding composition  1  to a melt crystallization cycle, d. repeating the melt crystallization cycle as many times as necessary to obtain as composition 2 a levulinic acid with a predetermined purity, and e. isolating the levulinic acid with a predetermined purity.

Claim (Index 10):
An isolation section in a plant for the production of levulinic acid, comprising at least one melt crystallizer.
