The catalyst sample was prepared by Sol-Gel method from C16H36O4Ti, CH3CH2OH CH3COOH and (NH4)2S2O8.By changing concentration of ammonium persulfate, baking time and baking temperature made solid super acid catalyst of S2Os2-/TiO2.Characterized their capacity and frame though the method of Infrared Spectroscopy and BET surface area techniques.The sucrose and lees biomass were catalyticed in autoclave under 160℃ and 24h With this catalyst, after it,using the liquid chromatography analysis the levulinic acid from the reaction on quantitative and qualitative.The results showed: the best experimental conditions for preparation of the catalyst was calcinating temperature at 500℃, baking time 5h, the solubility of ammonium persulfate 0.05mol/L,Levulinic acid of yield reached 47%.
