| 摘 要： | 以廉价的烷基胺为原料合成了SO3H-功能化的离子液体（IL）。采用NMR、ESI-MS、TG-DTG等手段对其结构及物性进行了表征。将该离子液体作为催化剂,考察反应条件对离子液体催化邻苯二酚叔丁醇(TBA)烷基化反应性能的差别。结果表明，在反应温度150 ℃、反应时间3 h、n(邻苯二酚):n(TBA):n(IL)为2:1:0.1的优化条件下，邻苯二酚的转化率、4-叔丁基邻苯二酚(4-TBC)的选择性分别可达41.5%和97.1%。与液体酸的催化效果接近。根据实验结果和模拟计算推测了可能的反应机理。

| Abstract: | SO3H-functionalized ionic liquids(IL) were synthesized by using tri-alkylamine and 1,4-butanesultone as the sources.The structures and physical properties of ILs were characterized by NMR,ESI-MS and TG-DTG.Their catalytic performances in the alkylation of catechol with tert-butyl alcohol(TBA) were investigated.The influences of reaction temperature,reaction time,reactant ratio,the amount and the recycle times of IL on the catalytic performance of IL in the tert-butylation of catechol were studied.Meanwhile,... |
