Reaction Steps
A mixture of 1.06 grams (10 millimoles) of p-xylene, 0.32 gram (2 millimoles) of N-hydroxyphthalimide, 0.018 gram (0.05 millimole) of acetylacetonatocobalt(III) Co(AA)3 and 25 milliliters of acetic acid was stirred in an oxygen atmosphere at a temperature of 100° C. for 12 hours. As a result, p-xylene was transformed into terephthalic acid (yield 71%) and p-methylbenzoic acid (yield 24%) with a transformation rate of 99%.
