2:Example 2
The reaction was monitored by HPLC for the conversion of methyl benzoquinone and the selectivity of conversion to methyl hydroquinone. The reactor was cooled and the reaction mixture was distilled to remove the methyl isobutyl ketone solvent. The residue was used for the isolation and purification of methyl hydroquinone. The weight of the residue obtained was about 34.59 g. To the above residue was added toluene (100 ml) and the resultant mixture was stirred for 12 hours at room temperature (25° C.). The precipitated methyl hydroquinone was filtered and the mother liquor cooled to about 10° C. to recover a second crop of the methyl hydroquinone. Total crude product obtained was 8 grams (g), which was subsequently washed with 4 volumes of toluene and dried.

EXAMPLE 8 The procedure of Example 7 was repeated, except that 0.5 mol of ortho-cresol was used in place of para-cresol and the peracetic acid was used at a proportion of 0.05 mol and the reaction temperature was held at 50° C. Analysis of the reaction mixture by gas chromatograph showed the conversion of ortho-cresol to be 4.00 percent and the yields of 3-methyl-1,2-dihydroxybenzene and 2-methyl-1,4-dihydroxybenzene to be 35.6 mol percent and 33.9 mol percent respectively based on the consumed peracetic acid.

Example 4 108.1 grams (1.0 mole) of o-cresol were heated to 100° C. and reacted according to the conditions set forth in Example 2. The temperature increased to 148° C. After 10 minutes, there was determined a hydrogen peroxide reaction of 97.9percent. In the reaction mixture, there were formed 7.37 grams (59.4 mmoles) of 3-methyl-pyrocatechol and 0.66 grams (5.3 mmoles) of 2-methyl-hydroquinone, which corresponds to a total yield of 66.1 mole percent based on the H2 O2 reacted.
