氯球固载化离子液体的制备及其在乙酸异戊酯合成中的应用
Synthesis of Supported Ionic Liquids With Chloromethyl Polystyrene and Its Application on Esterification for Isoamyl Acetate
摘要
Abstract
Three supported ionic liquids,includ ing [PS-Im-CaH6SO3H][HSO4],[PS-Im-CaH6SO3H][Cl]and [PS-Im-G3H6SO3H][Br],were synthesized with chloromethyl polystyrene.Then,isoamyl acetate was synthesized using these three supported ionic liquids as catalyst and acetic acid and isoamyl alcohol as raw materials.Among them,[PS-Im-CaH6SO3H][Cl] performed the best catalyst performance and was chosen for further study.The effects of reaction temperature,the dosage of catalyst,the molar ratio of acetic acid to isoamyl alcohol,and the reaction time on the yield were discussed.The results showed that the optimum conditions were:molar ratio of acetic acid to isoamyl alcohol was 2 ∶ 1,the quantity of catalyst was 2.5％ of the total mass of reactants,the reaction temperature was 115 ℃,and the reaction time was 2 h.Under these conditions,[PS-Im-C3H6SO3H][Cl] presented excellent catalyst efficacy and stability for synthesizing isoamyl acetate with the yield 96.8％,and the yield could still keep in a high value after reusing six times.关键词
