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

Ionic liquids having acid centers in the imidazolium cation and molybdenum, tungsten, and vanadium atoms in the anion were synthesized and their catalytic activity in the oxidation of organosulfur compounds was examined. The highest catalytic activity is exhibited by the ionic liquid containing a molybdenum atom. The infl uence exerted by the reaction duration and by the amount of the ionic liquid and oxidizing agent on the conversion of methyl phenyl sulfide. 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]. The efficiency of using polyfunctional catalysts based on ionic liquids containing a Br?nsted acid center in the cation for oxidation of organosulfur compounds as compared with application of a simple mixture of an ionic liquid and a transition metal salt.

In Situ Generated Organic Peroxides in Oxidative Desulfurization of Naphtha Reformate

Abstract: The paper describes a method developed for the oxidation of organosulfur compounds using organic peroxides generated in situ under the action of atmospheric oxygen on gasoline fraction after reforming. Naphtha reformate that contained dibenzothiophene as a model substrate was subjected to oxidative desulfurization by organic peroxides generated in situ under atmospheric oxygen. The study examined various catalytic systems, including immobilized Anderson-type polyoxometalates, and initiators, which, in combination, provided effective generation of alkyl hydroperoxides, selective oxidation of organosulfur compounds in the hydrocarbon feedstock, and a high conversion rate.

A μ-AsO4-Bridging Hexadecanuclear Ni-Substituted Polyoxotungstate

A novel tetrahedral μ-AsO4-bridging hexadecanuclear Ni-substituted silicotungstate (ST) Na21H10[(AsO4){Ni8(OH)6(H2O)2(CO3)2(A-α-SiW9O34)2}2]·60H2O (1) was made by the reactions of trivacant [A-α-SiW9O34]10- ({SiW9}) units with Ni2+ cations and Na3AsO4·12H2O and characterized by IR spectrometry, elemental analysis, thermogravimetric analysis (TGA), and powder X-ray diffraction (PXRD). 1 contains a novel polyoxoanion [(AsO4){Ni8(OH)6(H2O)2(CO3)2(A-α-SiW9O34)2}2]31- built by four trivacant Keggin [A-α-SiW9O34]10- fragments linked through an unprecedented [(AsO4){Ni8(OH)6(H2O)2(CO3)2}2]9+ cluster, where the tetrahedral AsO4 acts as an exclusively μ2-bridging unit to link multiple Ni centers; such a connection mode appears for the first time in polyoxometalate chemistry. Furthermore, the electrochemical and catalytic oxidation properties of compound 1 have been investigated.
