<p>Processes for the production of aromatic carboxylic acids is disclosed. The aromatic acids are produced by the liquid phase oxidation of a suitable acid precursor in a reaction medium comprising benzoic acid. According to one embodiment, the oxidation is carried out under plug flow reaction conditions in a plug flow reactor. The plug flow conditions can be achieved by the use of a series of continuous stirred tank reactors. In another embodiment, the oxidation is carried out in tow continuous stirred tank reactors fluidly connected in series. The preferred oxidation products are terephthalic acid, isophthalic acid, trimellitic acid, 2,6 naphthalene dicarboxylic acid, 1,5 napthalene dicarboxylic acid, 2,7 naphthalene dicarboxylic acid and phthalic acid.</p> |
