영어 초록
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-.
