Procedure

95.4 g of dodecyl 4-methylthiophenyl ether was dissolved in 400 ml of acetic acid, and further a dilute sodium hydroxide solution containing 0.5 g of sodium tangstate was added thereto. The resulting solution was heated at 80° C. with stirring. To the solution 66.3 g of 35% hydrogen peroxide was dropwise added. After the conclution of the addition, the reaction mixture was stirred for 2-hours under heating, and, after cooling, water was added to filtrate a precipitated crude crystal. The crude crystal was recrystalized by using methanol to obtain 101.5 g of dodecyl 4-methylsulfonylphenyl ether crystal.
