Procedure

The procedure of Comparative Example 1 was repeated, except phosphoric acid was added as a reaction catalyst in an amount corresponding to 1% by weight based on the amount of para-tert.-butyl phenol used. Consequently, the conversion of para-tert.-butyl phenol was 5.3%, 4-tert.-butyl pyrocatechol was formed in a yield of 52% based on the converted butyl phenol, and the conversion of peracetic acid was 96.0%.
