SO42-/ZrO2/USY催化纤维素醇解制备乙酰丙酸乙酯
Alcoholysis of Cellulose into Ethyl Levulinate Catalyzed by SO42-/ZrO2/USY
摘要
Abstract
Solid acid catalyst SO42-/ZrO2/USY was prepared by precipitation-dipping method.And the effects of different parameters on the conversion of cellulose to ethyl levulinate were also investigated.The results showed that 10％ SO42-/ZrO2/USY presented the highest catalyst activity when calcined at 400 ℃ for 3 h,and the high yield (38.1 mol％) of EL was obtained at 200 ℃ for 3 h,with a catalyst dosage of 10 g/L.EL yields of 50.77 mol％,39.55 mol％,44.87 mol％ and 43.59 mol％ could be obtained from fructose,glucose,sucrose and inulin,respectively.The catalysts were characterized by XRD,FT-IR,BET,NH3-TPD and TG-DTA.The prepared solid acid catalyst could be recycled and reused four times with good catalytic activity.关键词
