초록

본 논문에서는 친환경 촉매 중 하나인 이온성액체를 이용한 이소부탄 알킬레이션 반응에 대해서 연구하였다. 산성 이온성액체 중 하나인 1-Octyl-3-methylimidazolium-bromide-aluminum chloride를 촉매로 사용하였다. 최적의 반응조건을 규명하기 위하여 액체공간속도, 반응온도 및 이온성액체의 조성에 따른 반응성능에 대하여 조사하였다. 일정한 실험 조건에서 반응온도의 경우 80 ℃에서 최적의 반응성능을 보였고 이온성액체의 조성은 음이온 비가 0.56인 경우 우수한 반응특성을 보였다. 또한 반응조건에 따른 생성물의 수율을 예측할 수 있는 모델식을 통계학적 접근을 통해 완성하였다.

In this study, ionic liquids have been employed as a green catalyst in the alkylation of isobutane with 2-butene. One of acid ionic liquids, 1-octyl-3-methylimidazolium-bromide-aluminum chloride, was used in the reaction. Effects of the liquid hourly space velocity (LHSV), reaction temperature and composition of ionic liquids on the reaction performance were investigated in order to optimize reaction conditions. Under identical reaction conditions, the optimum reaction temperature was 80 ℃ and the ionic liquid with the anion composition of 0.56 showed an excellent reaction activity. Moreover, a correlation model was developed with a statistical approach to predict the product yields.

Keywords:Isobutane alkylation;ionic liquid;correlation model
