Method for preparing aromatic carboxylic acids from alkylaromatics by liquid-phase oxidation |
摘要 |
The present invention relates to a method for preparing aromatic carboxylic acid from alkylaromatics by liquid-phase oxidation. More particularly, the present invention relates to a method for preparing aromatic carboxylic acid from alkylaromatics by oxidation in acetic acid as solvent with oxygen-containing gas in the presence of cobalt/manganese/bromine complex catalyst, wherein nickel and carbon dioxide in an appropriate amount are added to increase an activity of cobalt/manganese/bromine complex catalyst. Especially nickel has a synergistic effect with carbon dioxide and maximize the to formation of the desired product having the corresponding carboxylic groups to the number of alkyl groups in a reactant.
