| Abstract: | Levulinic acid was synthesized over titanium sulfate solid acid catalyst from sucrose dissolved in water. Effects of calcination temperature on the activity and effects of catalyst dosage, sucrose concentration, reaction temperature and reaction time on the levulinic acid yield were investigated. Levulinic acid yield of 57.9% was obtained under the following condition： catalyst dosage 0. 5 g, sucrose concentration 50 g · L^- 1, reaction temperature 220 ℃ , reaction time 60 min. |
