Paragraph 0072; 0073; 0074-0079, (2019/06/30)
The invention discloses a crown ether type ionic liquid based on imidazole, benzimidazole and their derivatives. Cations of the crown ether type ionic liquid are imidazole, benzimidazole and their derivatives; anions include neutral or alkaline mononuclear and multinuclear anions; the mononuclear anions include Cl-, Br-, BF4-, PF6-, CF3COO-, CF3SO2-, (CF3SO2)N- and OH-; the multinuclear anions include AlCl4-, FeCl3- CuCl3- and AuCl4-. In some reactions, the crown ether type ionic liquid has the advantages of high reaction rate, high conversion rate, high reaction selectivity, reusability of acatalytic system and the like. In addition, the crown ether type ionic liquid also has a potential application prospect in terms of solvent extraction, separation and purification of matters, recycling of waste macromolecular compounds, fuel cells and solar cells, extraction of industrial waste gas, dissolution of geological samples, separation and treatment of nuclear fuels and nuclear wastes andthe like.

1,13-Dichloro-4,7,10-trioxatridecane (2-[2-(1-chloro-2-ethoxy)ethoxy]ethyl chloride) (3a) was synthesized by a chlorination of 1,13-dihydroxy-4,7,10- trioxatridecane (triethylene glycol). And it was treated with imidazole and sodium ethoxide to give the 1N,1N′(oxoethylene)-diimidazole (3b), which was then converted to ionic liquid-type crown ether (ILCE) 3 with a reaction with 1,9-dichloro-3,6-trioxaoctane (2a). Further, the anion of ILCE was exchanged by an anion-exchange method. Ultimately, we developed a very efficient synthetic pathway for ILCEs 1-4 which have various physical and chemical characteristics by a modification of the polyethylene glycol chain length and anions. 85Sr2+ was successfully extracted into the [(3,2)OEtIm][Cl] (3) phase, but it was not extracted into the [(2,2)OEtIm][Cl] (1), [(3,3)OEtIm][Cl] (2), and [(4,3)OEtIm][Cl] (4) phases.
