ABSTRACT:
A method of producing dehydration products from one more 5-carbon or 6-carbon sugars includes reacting said one or more sugars at 40-240.degree. C. for 1 to 96 hours in the presence of 5-90% sulfuric acid, separating the reaction products, and recovering levulinic acid. The sugars are can be generated from strong acid hydrolysis of biomass, such as rice straw, paper, cotton and other cellulosic materials.
