Investigation of 3,3′,5,5′-tetra-tert-butyl-4,4′-stilbenequinone-based catalyst in the reaction of liquid-phase oxidation of inorganic sulfides

This paper aims to investigate the liquid-phase oxidation reaction mechanism of inorganic sulfide in the presence of a catalyst based on 3,3 ′ ,5,5 ′ -tetra-tert-butyl-4,4 ′stilbenequinone dissolved in the kerosene fraction. The formation of intermediate and final products is also examined, pointing out that the products of catalytic sulfides oxidation are thiosulfate and sulfate. The study also looks at selective thiosulfate formation in the sulfide oxidation with stilbenequinone in an oxygen-free environment. The research results show that the regeneration of a catalyst based on 3,3 ′ ,5,5 ′ -tetra-tertbutyl-4,4 ′ -stilbenequinone is the rate-limiting step of the reaction, and a considerable amount of hydrogen peroxide is formed during catalyst regeneration. Using wastewater industrial pyrolysis processes, the proposed catalytic system is also tested under laboratory conditions.
