ABSTRACT:
A process and apparatus for manufacture of aromatic carboxylic acids comprises a liquid phase oxidation of aromatic hydrocarbon feed materials and treatment of a high pressure off-gas from the liquid phase oxidation to separate water and reaction solvent and preferentially apportion liquid phase oxidation by-product species between gas and liquid phase resulting from separation. Processes for making pure forms of aromatic carboxylic acid also are included.
