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

Claim (Index 19):
The process of  claim 13 , wherein the steps a) and b) are collectively reaction steps, the step f) is a solids filtration step, treating the first filtrate with the water immiscible solvent to form a water immiscible layer and a raffinate is an extraction step for extracting levulinic acid into the water immiscible solvent and wherein subjecting the water immiscible layer to distillation is a distillation step, wherein the mixture comprising levulinic acid is subjected to the steps of reaction, solids filtration, extraction and distillation, wherein the quantity of water, mineral acid, sugars and addition times can be varied, such that the water, mineral acid, the water immiscible solvent and optionally levulinic acid is recycled.
