실험 절차
As an example, reference is made to the production of phthalic anhydride with acetic acid as solvent. During oxidation of o-xylene as feedstock, phthalic acid and phthalic anhydride are obtained as products in the liquid-phase reactor. Therefore, not only the binary crystallization curves of phthalic acid in acetic acid or phthalic anhydride in acetic acid are used, but also those of the ternary system phthalic acid/phthalic anhydride/in acetic acid. By using the process of the invention, phthalic acid and phthalic anhydride are obtained as pure solid products. The acetic acid obtained as byproduct is recirculated into the reactor as solvent.
