General procedure for the synthesis of 1-ethyl-3-methylimidazole acetate from lead acetate trihydrate and 1-ethyl-3-methylimidazole bromide salt: First, 1-ethyl-3-methylimidazole bromide salt (0.2 mol) and lead (II) acetate trihydrate (0.1 mol) were dissolved in 30 mL and 70 mL of distilled water, respectively. After both were completely dissolved, the 1-ethyl-3-methylimidazole bromide salt solution was slowly added to the lead (II) acetate trihydrate solution under vigorous mechanical stirring. The reaction was stirred under nitrogen protection at a constant temperature of 35°C for 48 hours. Upon completion of the reaction, the reaction mixture was refrigerated at 3 °C for 12 h to promote the formation of a precipitate, which was subsequently removed by filtration. The filtrate was removed from water by distillation under reduced pressure to give the final 1-ethyl-3-methylimidazole acetate (EMIMAc), the product was a pale yellow viscous liquid with 0.02% moisture content and 0.004% bromide content in 93% yield.
