| 摘 要： | 制备了一种对水稳定的磺酸功能化咪唑离子液体1-甲基-3-丁磺酸基咪唑硫酸氢盐([BSMim]HSO4),并以其作为催化剂催化油酸酯化合成油酸甲酯。离子液体表现出良好的催化活性及稳定性。通过单因素实验确定最佳反应条件为:离子液体[BSMim]HSO4催化剂用量为油酸质量的20%,n(甲醇):n(油酸)=3∶1、反应温度75℃、反应时间4h,酯化率达85.3%以上,此外离子液体还具有稳定性好、可循环使用等特点。

| Abstract: | An ionic liquid stable in water, 1-（3-sulfonic acid） butyl-imidazole hydrosulfate with an alkanesulfonic acid group was prepared. Synthesis of methyl oleate from oleic acid catalyzed by the ionic liquid was studied. Ionic liquid [-BSMim-]HSO4 exhibited good catalytic activity and stability. Optimal esterification condition was obtained as follows： n（methanol）： n（oleic acid）= 3：1, reaction temperature 75℃, reaction time 4 h, dosage of ionic liquid = 20.0% of the oleic acid weight. The results showed acid and methanol, the yield of could be repeatedly used. that [BSMim]HSO4 has good methyl oleate reached 85.3%. activity for esterification of oleic The ionic liquid was stable and |
