Process for the isolation of levulinic acid |
| abstract |
The invention is directed to a process for the isolation of levulinic acid comprising the following steps: na. Performing acid catalyzed hydrolysis of a C6 carbohydrate-containing feedstock to obtain reaction product X, nb. 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, nc. Feeding composition 1 to a melt crystallization cycle, nd. Repeating the melt crystallization cycle as many times as necessary to obtain as composition 2 a levulinic acid with a predetermined purity, and ne. Isolating the levulinic acid with a predetermined purity. |
