Abstract:
The present invention is a method for producing an aromatic compound by substituting the sulfonic acid group in a sulfonic acid aromatic-ester with a hydrogen atom in the presence of a platinum group metal catalyst, wherein an alkali metal carboxylate and/or an ammonium formate are made to coexist in the system. According to the present invention, an aromatic compound where the sulfonic acid group in a sulfonic acid aromatic-ester is substituted with a hydrogen atom, can be produced efficiently with good operability without using metal magnesium.
