ABSTRACT:
Processes are disclosed for recovery of hydrogen bromide from one or more alkyl bromide compounds by hydrolyzing the alkyl bromide compounds to hydrogen bromide and corresponding alcohols, and simultaneously separating at least the alcoholic products of hydrolysis from aliphatic monocarboxylic acid solvent component. Also disclosed are process for preparing aromatic carboxylic acids by the exothermic, liquid-phase oxidation of an aromatic feedstock compound wherein the energy produced by the exothermic oxidation is efficiently recovered, and uses of water produced during the preparation of aromatic carboxylic acids are efficiently integrated into the process.
