Abstract
The disclosure relates to systems and methods for the production of levulinic acid, furfural, and formic acid from feedstock materials containing cellulose and hemicellulose. The levulinic acid, furfural, and formic acid can each be produced in relatively high yield simultaneously and in the same reactor vessel.

Abstract
Processes for producing formic acid from a carbohydrate-containing material include hydrolyzing a carbohydrate-containing material (e.g., cellulose) in the presence of a mineral acid to form an intermediate hydrolysate comprising one or more sugars, and hydrolyzing the intermediate hydrolysate to form a hydrolysate product including formic acid.

- C07C 51/44 - SeparationPurificationStabilisationUse of additives by change of the physical state, e.g. crystallisation by distillation
