Abstract :This work includes the preparation of ionic liquid 1,4-dimethylpiperidinium iodide [MMPip]I and its salts with ferric chloride as Lewis acid in different molar proportions [MMPip]I/nFeCl3 insert ignore into journalissuearticles values(n=1,2,3);. The prepared compounds were diagnosed by spectroscopic and physical methods such as 1H-NMR, FT-IR, elemental analysis insert ignore into journalissuearticles values(CHN); and other techniques. The thermal stability of these compounds was studied to use in the extractive desulfurization process insert ignore into journalissuearticles values(EDS);. The efficiency of these compounds in removing sulfur compounds from the petroleum model was examined using dibenzothiophene insert ignore into journalissuearticles values(DBT); with a concentration of 1000 ppm dissolved in the solvent of normal hexane. The results showed that the compounds used had an acceptable efficiency of up to 30% despite using medium amounts of the extracted agent relative to the oil model; these compounds have a promising future in extractive sulfur removal processes.
