In this study, new efficient catalysts have been developed for the oxidation of benzothiophenes commonly found in diesel fuel, such as benzothiophene, dibenzothiophene and 4,6-dimethyldibenzothiophene, to the corresponding sulfones with hydrogen peroxide in two-phase system including immiscible aqueous and organic phases. These catalysts are based on polyoxometalates comprising Keggin type heteropRANA OMAR HASSAN YAHYA2022-05-282022-05-2828696https://drepo.sdl.edu.sa/handle/20.500.14154/39501Thesis
