摘要/Abstract

摘要： 针对环氧苯乙烷制备过程中存在催化剂回收困难、催化剂活性低等缺陷，本文利用温控两相离子液体的"高温均相反应、低温两相分离"的特点及聚合物大分子在反应体系中性能稳定、不易流失的优点，结合过渡金属的高效催化能力设计合成出一种具有温控两相功能、催化活性高、流失量小、易回收的聚合型离子液体-纳米金催化剂。其催化苯乙烯环氧化反应结果显示：聚合离子液体-纳米金催化剂具有催化活性高、流失量小、回收方便的优点，苯乙烯的转化率为97.8%，环氧苯乙烷的选择性为81.9%。

Abstract: Due to the recycling difficulty and low activity of the catalyst during the preparation of styrene oxide,a new catalyst of gold nanoparticles stabilized by polymeric ionic liquid with thermoregulated biphasic function was synthesized,which has favorable properties of ‘mono-phase under high temperature, bi-phase under low temperature’,good stability and efficient catalytic ability. The results of catalyzing epoxidation of styrene showed that the catalyst has rather high catalytic activity with small loss and is easy to recycle. The conversion of styrene was up to 97.8%, while the selectivity of styrene oxide was 81.9%.

Key words: catalyst activation, thermoregulated biphasic, ionic liquid, conversion, selectivity
