| 摘要 |
The catalytic oxidation of a polymethyl-substituted stilbene compound with molecular oxygen in a liquid reaction mixture containing a lower fatty acid (e.g., acetic acid) as the reaction solvent, a soluble cobalt compound as the oxidation catalyst and preferably a reaction activator (e.g., methyl ethyl ketone, etc.) produces a benzene polycarboxylic acid as exemplified by the oxidation of 4,4'-dimethylstilbene to terephthalic acid.
