The study reports on the oxidation of sulfur compounds by sodium hypochlorite over molybdenum-based amphiphilic catalysts. The conversion of dibenzothiophene (DBT) was investigated as a function of the catalyst composition and reaction conditions. When sodium hypochlorite was used in combination with the heptamolybdate-anion-containing amphiphilic catalyst, sulfur compounds were found to be effectively oxidized even at room temperature. Under optimum process conditions (an oxidant to sulfur molar ratio of 4 : 1, a catalyst concentration of 0.5 wt %, and an acetonitrile volume of 1 mL), 100% conversion of DBT to sulfone had already been achieved after ten min of oxidation. The addition of acetonitrile to the reaction mixture was found to minimize the aggregation of catalyst particles and enhance the process performance. The catalyst demonstrated sustained activity over five oxidation cycles without regeneration.
