OXIDATION OF ALKYL AROMATIC COMPOUNDS TO AROMATIC ACIDS IN AN AQUEOUS MEDIUM
摘要
The present invention pertains to an improved method of oxidizing substitute d aromatic compounds (such as p xylene) to their corresponding aromatic acids (such as terephthalic acid). The improvement involves carrying out the oxidation reaction in an aqueous medium, wherein the aqueous medium contains at least 30 percent water, preferably up to 30 percent surfactant and preferably a low molecular weight material containing a hydrophilic end grou p as a co-surfactant. The reaction is carried out at a pH of less than 3.0.</S DOAB>
