发明名称 PROCESS FOR THE PREPARATION OF AROMATIC CARBOXYLIC ACIDS
摘要 A process for the catalytic oxidation of p-xylene is liquid phase to form terephthalic acid, consisting essentially of partially oxidizing p-xylene, in an initial stage of reactions, in an aliphatic carboxylic acid environment and in the presence of catalysts consisting of heavy metal salts, oxidation being completed, in a second stage of reaction, in the presence of a bromo-aldehyde by way of reaction activator.
