| titleOfInvention |
Catalyst for producing phthalic anhydride and process for producing phthalic anhydride |
| abstract |
The present invention relates to phthalic anhydride by gas phase oxidation of o-xylol and / or naphthalin, having at least one layer containing a catalyst, in particular an inert support and a catalytically active composition containing TiO 2 , which is treated on the support. It relates to a catalyst for producing. The present invention is characterized in that at least a portion of the TiO 2 used comprises the following properties: (a) the BET surface area is greater than 15 m 2 / g and (b) the primary crystal size is greater than 210 Angstroms. The invention also relates to a preferred method of preparing this type of catalyst and to the preferred use of titanium dioxide used according to the invention. |
