A METHOD FOR SOLVENT FREE HYDRODEBROMINATION IN THE PRODUCTION OF AROMATIC CARBOXYLIC ACIDS. |
摘要 |
<p>A process for hydrodebromination of a molten crude product aromatic carboxylic acid prepared by liquid phase oxidation utilizing bromine as a component of the oxidation catalyst which comprises: recovering the crude product aromatic carboxylic acid mixture by distillation; extracting the crude product aromatic carboxylic acid mixture with water; and passing the aromatic carboxylic acid mixture over a catalyst selected from Group VIII of the Periodic Table, optionally on a support, at a temperature of from about 150-320 DEG C and a hydrogen partial pressure of from about 20 to 300 psig, thereby producing aromatic monocarboxylic acids having bromine compounds significantly reduced.</p> |
