Three metal chloride anion based ionic liquids (MCABILs) were synthesized and characterized for high conversion of hydrogen sulfide (HS). The MCABILs were synthesized metathesis reaction and characterized by chemical spectroscopy such as FTIR, UV-Vis and CHNS elemental analysis. Then, the performance of those ionic liquids in HS conversion was evaluated at various temperatures and atmospheric pressure. The results indicated remarkable efficiency of metal chloride anion based ionic liquids in HS conversion. MCABILs managed to reach over 90% conversion efficiency at temperature as low as 50 °C, despite operating at atmospheric pressure. This occurs due to their high oxidation capability. The regeneration experiment indicated that all MCABILs can be recycled easily. Taken together, the research findings highlight the synthesis, characterization and high efficiency of MCABILs in promoting faster HS conversion as a catalyst.
合成了三种基于金属氯化物阴离子的离子液体(MCABILs),并对其用于高效转化硫化氢(HS)的性能进行了表征。通过复分解反应合成了MCABILs,并采用傅里叶变换红外光谱(FTIR)、紫外可见光谱(UV-Vis)和CHNS元素分析等化学光谱方法对其进行了表征。然后,在不同温度和大气压下评估了这些离子液体在HS转化中的性能。结果表明,基于金属氯化物阴离子的离子液体在HS转化中具有显著的效率。尽管在大气压下操作,但MCABILs在低至50°C的温度下仍能达到90%以上的转化效率。这是由于它们具有高氧化能力。再生实验表明,所有MCABILs都可以很容易地循环使用。综上所述,研究结果突出了MCABILs作为催化剂在促进更快的HS转化方面的合成、表征及高效性。
