摘要
合成了 N-甲基吡咯烷酮柠檬酸盐离子液体,通过表征表明,反应产物结构与设想合成产物结构一致.使用合成的离子液体催化剂对喹啉模拟汽油进行碱性氮脱除反应,考察不同反应条件下对碱性氮脱除率的影响,确定碱性氮脱除反应最佳工艺条件.实验结果表明,工艺条件条件为60 ℃、40min、剂油比1∶10时碱性氮脱除效果最佳,可达96.94％.在重复回收使用4次后碱性氮脱除率仍可达71.85％,碱性氮脱除效果较好.
Abstract
N-methylpyrrolidone citrate ionic liquid has been synthesized in this paper.The structure of the reaction product is consistent with that of the proposed synthetic product.The effects of different reaction conditions on the removal rate of basic nitrogen in quinoline simulated gasoline were investigated and the optimum process conditions were determined.The experimental results showed that the removal effect of alkaline nitrogen was the best when the process conditions were 60℃,40 min and the ratio of agent to oil was 1∶10,up to 96.94％.After repeated recycling for 4 times,the removal rate of basic nitrogen can still reach 71.85％,and the removal effect of basic nitrogen is good.
