Procedure

In the presence of 0.2% by weight of the same phosphorus-containing acid ester as indicated in Example 4, 1 mol or orthocresol and 0.2 mol of peracetic acid were caused to react at 50°C. Within 75 minutes after the start of the addition of peracid, the reaction product was analyzed by gas chromatography. Consequently, it was found that the conversion of peracetic acid was 99.8% and that there were produced 3-methyl-1,2-dihydroxy benzene and 2-methyl-1,4-dihydroxy benzene in amounts corresponding to 40.0% and 29.3% respectively.
