<p>A process for the production of formyl-substituted aromatic compounds which comprises hydrolyzing a dihalomethyl -substituted aromatic compound represented by general formula (1) into the corresponding formyl-substituted aromatic compound in the presence of an iron salt, wherein an aldehyde and an iron salt are dissolved in the dihalomethyl-substituted aromatic compound prior to the occurrence of hydrolysis, and after the resulting reaction system reaches a reaction temperature sufficient to cause the hydrolysis, water is added to the reaction system at a rate that not exceeds the rate of consumption of water. In general formula (1), Ar is an aromatic ring; X is a halogen atom; Rs are each independently a monovalent organic group; and l is an integer of 1 to 3, m is an integer of 1 to 5, and n is an integer of 0 to 5, with l, m and n satisfying the relationship: 1 = l + m + n = 6. By employing this process, the dihalomethyl group of a dihalomethyl-substituted aromatic compound having a trifluoromethyl group as another substituent can by hydrolyzed in a short time.</p> |
