摘要: Xylene derivatives, such as chloro-ortho-xylene, are oxidized in a solvent in the presence of at least one metal catalyst with addition of promoter after the reaction has proceeded to an intermediate stage of conversion to product mixture. The product comprises chlorophthalic acid or chlorophthalic anhydride.
