SBA-15负载三氯化铝催化合成乙酸环己酯
Catalytic synthesis of cyclohexyl acetate with SBA-15 supported AlCl_3
摘要
Abstract
Cyclohexyl acetate was synthesized from acetic acid and cyclohexanol,using SBA-15 supported AlCl3as catalyst.The factors influencing on synthesis,such as AlCl3 content in catalyst,molar ratio of acetic acid to cyclohexanol,the amount of catalyst,reaction time and the dosage of water-carrying reagent as well as the reusability of catalyst were investigated.At the same time,we established the kinetics model and obtained corresponding kinetics parameters of reaction.Experimental results indicated that SBA-15 supported AlCl3 had well catalytic selectivity and activity.The yield of cyclohexyl acetate still kept at 90% after being used 5 times and it could be reused.The optimum reaction conditions were found as following：0.2mol acetic acid,AlCl3 content in catalyst 10%,molar ratio of acetic acid to cyclohexanol 1.6：1,catalyst 0.6g,cyclohexane 10mL,reaction time 90min.The yield of cyclohexyl acetate was up to 95.8%.The apparent activation energy was 60.27kJ/mol and the rate equation of reaction was-dCA/dt=7.39×106exp（-7249.3/T）CACB.关键词
