Abstract:
A levulinic acid composition A having: a. at least 95 wt. % of levulinic acid; b. between 5 wppm and 5000 wppm of formic acid; and c. less than 1000 wppm of angelica lactone, based on the total weight of the composition. A process for the isolation of a levulinic acid composition, having the following steps: a. performing acid catalyzed hydrolysis of a C6 carbohydrate-containing feedstock to obtain reaction product X, b. subjecting of reaction product X to solid-liquid separation to provide a composition 1, c. feeding composition 1 to at least two purification steps to treat composition 1 to obtain a levulinic acid composition, wherein a second or a further purification step is a melt crystallization step.

Claim (Index 15):
The composition according to  claim 3 , wherein the amount of formic acid is between 10 wppm and 1000 wppm, based on the total weight of the composition, and wherein the amount of formic acid is between 20 wppm and 500 wppm, based on the total weight of the composition.
