反応手順

First, 7 ml of methanesulfonic acid was added to 10 g of N-vinylimidazole, and the resultant mixture was stirred for 3 hours at a temperature kept at 0° C. and then added dropwise to diethyl ether cooled with dry ice. The resultant mixture was rapidly filtered by suction using a Nutsche aspirator provided with a glass filter to recover crystals on the glass filter. The crystals were dried to obtain 19.2 g of N-vinylimidazolium methanesulfonate. The yield was 95%, and the melting point was 5° C.
