Abstract: PURPOSE:To improve the yield of a substituted phthalic acid compound useful as an intermediate of agricultural chemicals and pharmaceuticals, and to facilitate the purification of the compound, by dehydrogenating a substituted tetrahydrophthalic acid compound with sulfur, and heating together with water after dehydrogenation. CONSTITUTION:A substituted tetrahydrophthalic acid compound having a substituent group at least a part of 3-, 4-, 5- and 6-positions (e.g. 4-methyl-1,2,3,6- tetrahydrophthalic anhydride) is heated at about 200-300 deg.C in the presence of sulfur to effect the dehydrogenation. Subsequently, 1pt.wt. of the reaction product is heated together with 2-5pts.wt. of water at 90-150 deg.C for about 1-5hr preferably removing the hydrogen sulfide produced by the treatment from the system to obtain a substituted phthalic acid, which is optionally subjected to the dehydrative cyclization to obtain a substituted phthalic acid compound. EFFECT:The process can be carried out in improved efficiency with simple operation using an inexpensive material.
