Abstract

In this study the cycloaddition of glycidyl methacrylate (GMA) and $CO_2$ using ionic liquid as catalyst was performed for the technology of $CO_2$ reduction. The structure of synthesized cyclic carbonate, [2-oxo-1,3-dioxolan-4-yl]methacrylate (DOMA) was analyzed and confirmed by FT-IR and $^1H$-NMR. The change in conversion with respect to reaction time was investigated using $^1H$-NMR. Interestingly, the ionic polymerization of vinyl groups and crosslinking reaction between cyclic carbonate rings of DOMA were observed following completion of cycloaddition.

온실가스인 $CO_2$를 저감하기 위한 기술로 본 연구에서는 이온성 액체를 이용하여 epoxide계 화합물인 glycidyl methacrylate (GMA)와 $CO_2$의 고리화 첨가 반응(cycloaddition)을 통해 cyclic carbonate를 합성하였다. 합성된 cyclic carbonate인 [2-oxo-1,3-dioxolan-4-yl]methacrylate (DOMA)는 FT-IR과 $^1H$ NMR을 이용하여 그 구조를 확인하였다. 또한 $^1H$ NMR을 통하여 계산된 조성비를 이용하여 전환율과 시간의 관계를 관찰하였다. DOMA로 전환이 모두 이루어진 이후에는 DOMA의 이중결합이 잔존하는 이온성 액체로 음이온 중합, cyclic carbonate ring의 가교반응에 의한 고분자가 형성되었다.
