| titleOfInvention | Catalyst for vapor phase oxidation for producing phthalic anhydride from ortho-xylene and / or naphthalene, preparation method thereof, and vapor phase oxidation method using the catalyst |
| abstract | PROBLEM TO BE SOLVED: To provide a catalyst suitable for producing phthalic anhydride from orthoxylene and / or naphthalene, a preparation method thereof, and a gas phase oxidation method of orthoxylene and / or naphthalene using these catalysts. SOLUTION: In a gas phase oxidation catalyst for producing phthalic anhydride from orthoxylene and / or naphthalene having a catalytically active component supported on an inert carrier, the carrier has a specific resistance of water after the following treatment as the carrier. A catalyst characterized by using a catalyst having a 20,000 Ωcm (25 ° C.) or more: (Treatment method) Take 300 ml of carrier in a 500 ml conical beaker, dry at 120 ° C. for 2 hours, add (water absorption + 220) ml of pure water, and heat at 90 ° C. for 30 minutes under normal pressure. Here, the amount of water absorption is represented by the following formula: water absorption amount = A / B, where A = 300 (ml) × packing density (g / ml) × water absorption rate (wt%) / 100 B = water Density (g / ml).
