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.
A continuous process for preparing aromatic acid from a corresponding methyl substituted aromatic compound by catalytic liquid-phase oxidation of the methyl groups with a dioxygen-containing gas in a solvent comprising a lower aliphatic monocarboxylic acid at an elevated temperature and pressure and in the presence of an oxidation catalyst comprising a heavy metal component and a source of bromine, which process comprises:
A continuous process for preparing dicarboxylic aromatic acid by liquid-phase oxidation of a corresponding benzene having two oxidizable alkyl or acyl ring substituents or an oxidizable alkyl and acyl ring substituent in non-adjacent positions or a corresponding naphthalene having two oxidizable alkyl or acyl ring substituents or oxidizable alkyl and acyl ring substituent, with a dioxygen-containing gas in a solvent at an elevated temperature and pressure and in the presence of an oxidation catalyst comprising a heavy metal component and a source of bromine, which process comprises:
