Abstract
In this work, an ionic liquid composed of 1,4-butyl methyl chloride [bm-Im]Cl and its salts in varying molar proportions [bm-Im]FeCl4 and [bm-Im]2MCl4 (M2+= Co, Ni, Cu) are prepared using metal chloride as Lewis acid. FT-IR, elemental analysis (CHN), 1H-NMR, and other spectroscopic and physical methods were used to diagnose the prepared compounds. To employ these compounds in the extractive desulfurization process (EDS), their thermal stability was investigated. The effectiveness of these compounds in eliminating sulfur compounds from the petroleum model was investigated by dissolving 1000 parts per million (ppm) of Dibenzothiophene (DBT) in a standard hexane solvent. Despite using medium amounts of the extracted agent compared to the oil model, the results showed that the compounds used had an acceptable efficiency; these compounds have a promising future in extractive sulfur removal processes In this work, an ionic liquid composed of 1,4-butyl methyl chloride [bm-Im]Cl and its salts in varying molar proportions [bm-Im]FeCl4 and [bm-Im]2MCl4 (M2+= Co, Ni, Cu) are prepared using metal chloride as Lewis acid.
