Reaction Conditions

Reaction Steps

25 grams of phthalic anhydride were dissolved in 150 ml of ethyl acetate and cooled to 10° C. Then there were added 3 grams of Lewatit MP 62. Subsequently, within 15 minutes, there were dropped in at the same temperature with stirring 11.5 grams of 50 wt. % hydrogen peroxide. Stirring was containued for 1 hour, whereby the temperature of the mixture increased to about 20° C. Then there was separated off the ion exchanger and there were obtained from the solution 25.4 grams of monoperoxyphthalic acid having an AO content of 7.0%.
