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28min,催化剂投加量0.05mol/L,蔗糖浓度0.3mol/L,该条件下乙酰丙酸产率为47.33%。
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.
