실험 절차

With reference to FIG. 4, 0.14 mmloe of 1-vinylimidazole, being the imidazolium liquid monomer, and 50 ml of toluene are mixed to obtain a mixture, followed by sequentially dropping 0.16 mmole of 2-bromoethanol into the mixture to trigger off an alkylation of the 1-vinylimidazole and the 2-bromoethanol. Then, a solution with two phase of layering is obtained after three days of reaction, wherein the lower layer of the solution is further isolated and repeatedly washed by toluene and ether, followed by being condensed and dried in vacuo for 1 hour, to obtain 1-(2-hydroxyl-ethyl)-3-vinylimidazolium bromide (also known as HEVIMB).
