摘要
Instantaneous aqueous extraction of toluic acid salts is the basis for a novel selective process for the oxidation of a single methyl group of various xylenes; aqueous hypochlorite is inert towards methylbenzenes at pH higher than 9.0, however, in the presence of an organic solvent, a Ru catalyst and a phase transfer agent, rapid oxidation to benzoic acids is observed at 25 degrees C.
