And the article was included in Shiyou Huagong Gaodeng Xuexiao Xuebao in 2012.Application In Synthesis of 1-Methyl-3-propylimidazolium Chloride This article mentions the following:
A series of alkylimidazolium chlorate type of ionic liquids (ILs) bearing different length of alkyl chains were synthesized. The desulfurization for the model or true oil using ILS as extracting agent were investigated under different conditions. The results show that the best desulfurization rate was obtained after 90 min under the condition of V[C7min]ClO3/VOil = 5 : 1 at 60°C using [C7min]ClO3 as extracting reagent. The sulfur removal reached 82.15% for the model oil ([S]0 = 1160 μg/g) 56.09% for the FCC gasoline ([S]0 = 117 μg/g) and 53.01% for the FCC diesel ([S]0 = 1974 μg/g). After the reaction, the fuel oil and ionic liquid can be separated simply by decantation. The ILs were then purified by fractional distillation The ILs can be recycled at least for 5 times without significant loss of activity. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Application In Synthesis of 1-Methyl-3-propylimidazolium Chloride).
1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8) belongs to imidazole derivatives. The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with a Imidazole derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.Application In Synthesis of 1-Methyl-3-propylimidazolium Chloride
