A series of N-methylimidazolium hydrosulfate type of ionic liquids (ILs) bearing different length of alkyl chains were synthesized. The ionic liquids were applied both as extracting reagent and catalyst for the model or true oil desulfurization using hydrogen peroxide (35%) as the oxidant. The desulfurization conditions were optimized by varying extraction time, the ratio of ILs/oil, temperature and so on. Under the optimal conditions, the ILs were also used for the desulfurization of FCC gasoline and diesel. The results show that, [C3mim]HSO4 has the highest desulfurization rate. The best desulfurization rate was obtained after 1.5 h under the condition of V ([C3mim]HSO4)/V (H2O2)/V (oil) = 1 : 1 : 30 at 60°C for the model oil (88.38%) and diesel (80%). The sulfur content of FCC gasoline has decreased to 10 μg/g below, which shows a very promising perspective for industrial applications. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4HPLC of Formula: 478935-29-4).
1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.HPLC of Formula: 478935-29-4
