Oxidation of Methylphenyl Sulfide with Hydrogen Peroxide in the Presence of Crown Ethers and Their Complexes with Amino Acids

摘要

The oxidation of methylphenyl sulfide, benzothiophene, and dibenzothiophene with hydrogen peroxide in the presence of crown ethers was studied. The major product of the oxidation was methylphenyl sulfoxide. The reaction was retarded by the addition of amino acids, which formed 1:1 complexes with the crown ethers. The oxidation of the diesel fraction with hydrogen peroxide can decrease the sulfur content in it.
