Abstract
Terephthalic acid is prepared by oxidizing a substantially homogeneous liquid reaction mixture, comprising p-toluic acid, optionally in admixture with p-xylene and partially oxidized p-xylene derivatives, 5% to 80% by weight of water, and a catalytically-active metal compound selected from manganese compounds, cobalt compounds and mixtures thereof, with a molecular oxygen-containing gas. At least a minimum amount of M millimoles of the catalytically-active metal compound per kg of the liquid reaction mixture is used, wherein M is defined by the following equation: <IMAGE> wherein Y represents the molar ratio of water/p-toluic acid in the reaction mixture, x represents the molar ratio of manganese/total manganese + cobalt in the catalyst composition <IMAGE> A equals about 0.200, B equals about 10.9, C equals about 4.35; and D equals about 0.0724.t
