Investigation on aluminum salt/1,3-dialkyl imidazolium salt catalyzed conversion of sucrose to methyl levulinate
摘要
Abstract
Investigation shows that aluminum salts and their combinations with 1,3-dialkylimmidazolium salts are efficient catalysts for the conversion of sucrose to methyl levulinate in methanol.Especially,the combinations of aluminum salts with 1,3-dimethylimidazolium hydrogen sulfate have high activity for the methyl levulinate synthesis from sucrose and high methyl levulinate yield was obtained.The investigation examined the co-catalysis of aluminum salts and 1,3-dimethylimidazolium hydrogen sulfate.The effects of reaction time,reaction temperature,and catalyst loading on methyl levulinate yield were studied.The reaction conditions were optimized.It was found that good yield(70% in mol) of methyl levulinate could be obtained at 140℃ by reaction 3 h with 1,3-dimethylimidazolium hydrogen sulfate and Al(CH3SO3)3 loading of 0.500 g and 0.500 g,respectively.关键词
