Abstract: Production of levulinic acid catalyzed by ferric chloride supported on activated carbon was studied. The response surface method, a useful tool for multi-factor process optimization, was used through Box-Beknhen experiment design. The selected four factors were reaction temperature, reaction time, dose of catalyst and concentration of sucrose. The optimized experiment conditions were: reaction temperature 218℃, reaction time 28min, dose of catalyst 0.05 mol/L, concentration of sucrose 0.3 mol/L. The maximum levulinic acid production reached 47.33% under the optimized experiment conditions.

摘要： 采用活性炭固载氯化铁为催化剂，催化蔗糖转化为乙酰丙酸。利用响应面这一多因素过程优化的有效工具，通过Box—Beknhen实验，对反应温度、反应时间、催化剂投加量和蔗糖浓度4个因素进行了优化。优化后的实验条件为：反应温度218 ℃，反应时间28 min，催化剂投加量0.05 mol/L，蔗糖浓度0.3 mol/L，该条件下乙酰丙酸产率为47.33%。
