이온성 액체 촉매를 이용한 Tricyclopentadiene 합성에 관한 연구 = A Study on the Synthesis of Tricyclopentadiene Using Ionic Liquid Catalysts

다국어 초록 (Multilingual Abstract)

Tricyclopentadiene (TCPD) as a next generation high density fuel was synthesized by Diels-Alder oligomerization reaction of DCPD. TCPD was prepared by ionic liquid (IL) catalysts with combination of cationic and anionic precursors. Two kinds of anionic precursors such as copper(Ⅰ) chloride (CuCl) and iron(Ⅲ) chloride (FeCl3) and cationic precursors such as triethylamine hydrochloride (TEAC) and 1-butyl-3-methylimidazolium chloride (BMIC) were used. The preparation of TCPD using IL catalyst was superior to that using Diels-Alder reaction in terms of DCPD conversion and TCPD yield. In addition, TCPD yield was correlated with Lewis acidity by changing the ratio of anionic and cationic precursors. The TCPD yield was higher when using CuCl as anionic precursor than that of using FeCl3. Control of Lewis acidity by changing the molar ratio of anionic and cationic precursors could further improve TCPD yield as well.
