Procedure

The 2-methyl-6-acetyloxynaphthalene obtained in the first half of Example 1 was not recrystallized from acetic anhydride prior to oxidation, but was directly oxidized with molecular oxygen in the presence of the same catalyst as in Example 1 in the same reactor as in Example 1. The reaction time was 2.4 hours. After the reaction, the product was analyzed. The conversion of 2-methyl-6-acetyloxynaphthalene was 55.5 mole%, and the yield of 6-acetyloxy-2-naphthoic acid was 40.0 mole% (selectivity 72 mole%). At this time, 8.88 mole% of 6-acetyloxy-2-naphthaldehyde was formed.
