  A process for producing a substituted phthalic acid which comprises heating a substituted tetrahydrophthalic acid compound having a substituent in at least one of the 3-, 4-, 5- and 6-positions in the presence of sulfur to dehydrogenate it, and heat-treating the product in the presence of water optionally together with an organic solvent. As required, the heat-treated product is dehydrocyclized to form a substituted phthalic acid anhydride.
