Abstract
Authors synthesized poly-p-vinyl benzoic acid-ion exchange resin which was converted to the peracid type resin by using hydrogen peroxide and methanesulfonic or p-toluenesulfonic acid. The peracid type resin of oxidation capacity 2.13 m eq / g was obtained and the conversion of COOH to COOOH was 48.4% in the best condition. The conversion of COOH to COOOH increased from 15 to 30% with increase in the cross-linking degree from 1 to 41%. The conversion rate was relatively slow as comparing with that observed in the case of peracid type XE-89, but the loss in the conversion was little. The stability in the air was better than that in the case of peracid type XE-89, but worse at 40°C in benzene, methanol and dioxane. Cyclohexene and methyl oleate were epoxidized by the peracid type resin in the yields of 5060%.
