研究了在离子液体催化剂存在下，二氧化碳对烯丙基缩水甘油醚（AGE）的加成反应。使用基于1-乙基-3-甲基咪唑鎓（EMIm）、1-丁基-3-甲基咪唑鎓（BMIm）和1-己基-3-甲基咪唑鎓（HMIm）与不同阴离子如Cl−、BF 4 −、PF 6 −的离子液体作为催化剂。反应在50 mL不锈钢高压釜中进行。咪唑盐离子液体的结构对烯丙基缩水甘油醚的转化率有影响，烷基链长较大的阳离子和亲核阴离子较多的咪唑盐离子液体具有较好的反应活性。反应温度和二氧化碳压力促进了二氧化碳向AGE的加成。
The addition of carbon dioxide to allyl glycidyl ether (AGE) was investigated without using any solvent in the presence of ionic liquid as catalyst. Ionic liquids based on 1-ethyl-3-methylimidazolium (EMIm), 1-butyl-3-methylimidazolium (BMIm), and 1-hexyl-3-methylimidazolium (HMIm) with different anions such as Cl−, BF4−, PF6−were used as catalysts. The reaction was performed in a 50mL stainless steel autoclave. The conversion of allyl glycidyl ether was affected by the structure of imidazolium salt ionic liquids; the one with the cation of bulkier alkyl chain length and with more nucleophilic anion showed better reactivity. Reaction temperature and carbon dioxide pressure enhanced the addition of carbon dioxide to AGE.
