PREPARATION OF AROMATIC ACIDS

摘要

An aromatic acid is prepared by reacting in the liquid phase an aromatic with carbon monoxide in the presence of a catalyst selected from the group consisting of palladium and ferric chloride and bromides and mixtures thereof and an anhydrous organic liquid inert to the above reactants and catalyst at a temperature between about 100 DEG C. and 300 DEG C. and at a pressure to maintain liquid phase, and then hydrolyzing the resultant carbonylated compound to said aromatic acid.
