摘　　要：文中合成了三种离子液体[bmim][Gly]、[bmim][Ala]和[bmim][Lys],以改善氨基酸盐溶液的吸收及解吸性能,讨论了不同合成条件下,反应物的产率,并确定了最佳反应条件。之后将合成的三种离子液体配成浓度为0.5 mol/L溶液,与对应浓度的氨基酸盐溶液进行吸收与解吸性能比较,结论显示氨基酸离子液体的吸收和解吸性能都很优越,尤其再生效率可达到100%,这对于实现吸收剂的循环再生利用将是一个巨大的进步。Three ionic liquids [ bmin] [ Gly] , [ bmin] [ Ala] and [ bmin] [ Lys] were synthesized to improve the absorption and desorption performance of amino acid salt solution. The reaction product ratios under different synthesis conditions were discussed and the optimum reaction conditions were determined. New ionic liquids at the concentration of 0.5mol/L were prepared, then compared with the absorption and desorption performance of same concentration of amino acid solution. Results showed that the absorption and desorption performance of amino acid liquids were more excellent, especially the regeneration efficiency could reach 100% , which would be a huge progress for the absorbents recycling.
