【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%。更多还原

【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.更多还原
