A method of producing dehydration products from one or more 5-carbon or 6-carbon sugars includes reacting said one or more sugars at 40 DEG -240 DEG C. for 1 to 96 hours in the presence of 10-90% sulfuric acid, separating the reaction products, and recovering levulinic acid. The sugars can be generated from strong acid hydrolysis of biomass, such as rice straw, paper, cotton and other cellulosic materials.
