摘要

摘要: 以N-丁基咪唑、HCl和CuCl为原料两步法合成了离子液体[BIm]Cl/CuCl,并用傅里叶变换红外光谱FT-IR和傅里叶变换离子回旋共振质谱FT-ICR MS对其结构进行表征。采用差热扫描量热仪DSC、FT-IR以及紫外可见光谱UV-vis对吸附硫醇的[BIm]Cl/CuCl进行分析,讨论了[BIm]Cl/CuCl吸附硫醇的作用机制。以[BIm]Cl/CuCl为吸附剂,采用吸附蒸馏工艺脱除MTBE中的硫化物,MTBE硫含量可降低至5 μg/g以下,吸附剂进行多次循环使用且脱硫效果无明显降低。

Abstract: Ionic liquid [BIm]Cl/CuCl was synthesized by two-step synthesis using 1-butylimidazole, HCl and CuCl as raw materials. Structure of [BIm]Cl/CuCl was characterized by FT-IR and FT-ICR MS. The interactions between [BIm]Cl/CuCl and thiol were analyzed by DSC, FT-IR and UV-vis spectra. The mechanism for the adsorption removal of thiol by [BIm]Cl/CuCl was discussed. It was found that the sulfur content in methyl tert-butyl ether (MTBE) could be reduced to lower than 5 μg/g via adsorptive distillation desulfurization process with [BIm]Cl/CuCl as adsorbent, and that significant deterioration in the desulfurization efficiency of adsorbent was not observed in a few recycling tests.
