The invention provides a sulfocompound
selective catalytic oxidation reaction system in an aqueous phase. A catalyst, a sulfocompound and 30%
hydrogen peroxide are stirred for 1.5-2 hours under
room temperature in the aqueous phase according to the
molar ratio of the catalyst to the sulfocompound to the 30%
hydrogen peroxide being 1 to 400 to 1200, wherein the conversion rate is greater than 97%, and the selectivity of the product namely sulphone is greater than 94%; the catalyst, the sulfocompound and the 30%
hydrogen peroxide are stirred for 6 hours under the
room temperature in the aqueous phase according to the
molar ratio of the catalyst to the sulfocompound to the 30%
hydrogen peroxide being 1 to 1666 to 1666, wherein the conversion rate is greater than 90%, and the selectivity of the product namely sulphoxide is greater than 80%. According to the
reaction system disclosed by the invention, after the reaction is completed, extraction is performed with
ethyl acetate, after an organic phase is separated, the catalyst dispersed in the aqueous phase can be directly used for the next catalytic reaction, and the catalytic activity, the conversion rate and the selectivity are all kept. The sulfocompound
selective catalytic oxidation reaction system disclosed by the invention has the advantages that water is used as a
solvent, the reaction condition is mild, the catalytic activity is high, the selectivity of products is good, the consumption of the catalyst is low, and the catalyst can be repeatedly used.
