Abstract:
The invention describes processes to prepare levulinic acid, formic acid and/or hydroxymethyl furfural from various biomass materials.

Claim (Index 1):
A process to prepare levulinic acid comprising the steps:\n a) heating an aqueous solution of a mineral acid to about 60\u00b0 C. to about 110\u00b0 C. in a reactor, wherein the reactor is a batch reactor; and b) continuously adding an aqueous mixture of sugars to the heated aqueous acid of step a) in the batch reactor over a period of from about 0.1 to about 40 hours to form a reaction mixture including levulinic acid, wherein the mineral acid percentage by weight is from about 20 to about 80 percent of the reaction mixture.
