Ionic liquids are well-known as green solvent. Besides that, it is also have many special criterion that inspired researcher to do deep research on the ability of ionic liquids in extracting sulfur compounds from crude oil. Instead, problems occur at plant due to the lack performance of current technology in extracting aromatic sulfur compounds which is hydrodesulfurization (HDS) make all the effort become more concentrated. Hence, the aim of this project is to find the best method of extraction by using ionic liquids. After going through related literatures, methods and procedures of experiment were proposed. To make the study more interesting, this research started with synthesis of ionic liquid which is [BMIM][DBP]. It is followed by the characterization of ionic liquids in order to confirm that ionic liquid has been synthesized successfully. An alternative to crude oil, dodecane is used as model oil. After synthesis, extraction and oxidation of Benzothiophene (BT) were conducted. The result shows that, [BMIM][DBP] can extract BT from dodecane model oil from 6% up to 54%. As a conclusion, the ionic liquid showed the successful in extracting sulfur compounds from crude oil model.
