Catalytic Activity of Polyfunctional Ionic Liquids in Oxidation of Model Sulfur Organic Compounds

Аннотация

Ionic liquids based on 1-methylimidazole were synthesized. The liquids contain Bronsted acid centers in the cation and a transition metal atom in the anion. The polyfunctional ionic liquids synthesized in the study are effective catalysts for the oxidative desulfurization process. The conditions are found for reaching the 100% conversion of methyl phenyl sulfide under mild conditions in the presence of the catalysts, ionic liquids [ionic liquid: 3-(carboxymethyl)-1-methyl-1H-imidazol-3-ium molybdate with S: Mo molar ratio = 24 ∶ 1, 2 h, 40°C, H₂O₂: S molar ratio = 12 ∶ 1].
