부틸글리시딜에테르와 이산화탄소의 부가반응에 대한 이온성 액체의 촉매 성능 고찰 = Catalytic Performance of Ionic Liquids for the Cycloaddition of Carbon Dioxide and Butyl Glycidyl Ether

다국어 초록 (Multilingual Abstract)

The synthesis of cyclic carbonate from butyl glycidyl ether (BGE) and carbon
dioxide was performed in the presence of three different types of ionic liquid : quarternary
ammonium salt, alkyl pyridinium salt, and alkylimidazolium salt. Ionic liquids of different alkyl
groups (C3, C4, C6 and C8) and anions (Cl-, Br- and I-) were used for the reaction which was
carried out in a batch autoclave reactor at 60~120 ℃. The catalytic activity was increased
with increasing alkyl chain length in the order of C3 < C4 < C6. But the ionic liquid with
longer alkyl chain length (C8) decreased the conversion of BGE because it is too bulky to
form an intermediate with BGE. For the counter anion of the ionic liquid catalysts, the BGE
conversion decreased in the order Cl- > Br-
> I-
.
