Abstract: 1. A PROCESS FOR THE PRODUCTION OF PHTHALIC ANHYDRIDE BY OXIDATION OF O-XYLENE OR NAPTHALENE WITH OXYGEN OF A GAS CONTAINING OXYGEN IN THE PRESENCE OF A SUPPORTED CATALYST CONTAINING VANADIUM PENTOXIDE IN A REACTION TUBE WHEREIN THE INNER SURFACE OF SAID TUBE IN WHICH THE OXIDATION IS CARRIED OUT HAS BOTH SMOOTH AND ROUGHENED INNER SURFACE PORTIONS WITH 30 TO 60% OF SAID INNER SURFACE BEING ROUGHENED BY ANNULAR OR SPIRAL DESPRESSIONS HAVING A WIDTH OF 0.5 TO 30 MIM. AND A DEPTH OF 0.2 TO 1 MM.
