Catalytic oxidative desulfurization of model fuel over MnWO4 was written by Li, Jia-hui;Hu, Jia;Zhao, Rong-xiang;Li, Xiu-ping. And the article was included in Yingyong Huagong in 2014.Synthetic Route of C4H7ClN2 This article mentions the following:
Manganese tungstate was prepared by direct precipitation method. The oxidative desulfurization activity was improved by high temperature calcination activation and activation of hydrogen peroxide. Activated MnWO4 as catalyst, hydrogen peroxide as the oxidant, imidazole fluoroborate as extraction agent, dibenzothiophene (DBT) in simulated oil was removed by oxidation The influence of reaction time, reaction temperature, amount of catalyst, amount of oxidant, type of extractant, type of sulfide, etc. on catalytic oxidative desulfurization was studied. The results indicated the optimized desulfurization conditions were as follows: temperature 50掳C, 0.3 mL of hydrogen peroxide, 0.03 g of catalyst, imidazole tetrafluoroborate as the extractant, and the reaction time was 60 min. The desulphurization rate was up to 90%. The reaction system could recycle 5 times with a slight decrease in activity. In the experiment, the researchers used many compounds, for example, 1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3Synthetic Route of C4H7ClN2).
1-Methyl-1H-imidazol-3-ium chloride (cas: 35487-17-3) 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鈥揅6) is higher than in water and generally decreases with a Imidazole based anticancer drug find applications in cancer chemotherapy. It is used as buffer component for purification of the histidine tagged recombinant proteins in immobilized metal-affinity chromatography (IMAC).Synthetic Route of C4H7ClN2
