摘要： The invented process produces phthalic anhydride through gas-phase catalytic oxidation of ortho-xylene and/or naphthalene with an oxygen-containing gas using one or more fixed bed reactors. In the process, the gas-phase catalytic oxidation process is performed in three or more individual catalytic layers, and the conversion rates of ortho-xylene and/or naphthalene in the individual layers are controlled within specific ranges. The process is capable of providing phthalic anhydride in a high yield, is capable of minimizing deterioration of catalysts with time, and is capable of continuously stably producing phthalic anhydride in safety, even when a high concentration material gas is fed.
