- Abstract
The kinetics of liquid-phase oxidation by oxygen from sodium sulfide was studied in an aqueous medium in the presence of a catalyst based on 3,3′,5,5′-tetra-tert-butyl-4,4′-stilbenequinone dissolved in kerosene fraction. It was found that 3,3′,5,5′-tetra-tert-butyl-4,4′-stilbenequinone selectively oxidizes sodium sulfide to sodium thiosulfate. The reaction orders in sodium sulfide, oxygen, and the catalyst were determined. The reaction mechanism was proposed.
