Abstract

PURPOSE: To prepare the titled compund useful as industrial solvent, paint solvent, starting raw material of various industrial products, etc., by oxidizing a sulfide compound in the presence of visible light and oxygen, using a specific sensitizer for heterogeneous photo-sensitized oxidation.
CONSTITUTION: The organic sulfur oxide of formula II (X is S or O; m and n are 0 or 1) is prepared by oxidizing the compound of formula I (R is alkyl, aryl etc.; R' is H, alkyl, aryl, etc.; l is 0 or 1), e.g. dimethyl sulfide, dipropyl disulfide, methanethiol, etc., in the presence of oxygen and visible light, using a sensitizer for heterogeneous photo-sensitized oxidation. The sensitizer is a sensitizing substance having a discoloration degree of class 4W8, and the dissolved oxygen consumption (ΔDO) of ≥0.5 (e.g. aromatic ketone compound, aromatic heterocyclic compound, aromatic hydrocarbon, etc.) supported by a carrier in an actively dispersed state.
