ThenThe invention relates to a solid phase catalyst, with the componentsnPalladium (Pd) in the form of palladium metal and / or palladium oxidenand at least one other, essentially in oxidic formnpresent component, selected from the group consisting of antimonyn(Sb), bismuth (Bi) and tin (Zn). The components arenon a suitable oxidic support, preferably titanium oxide,nbefore and are by impregnationnof the wearer,nDrying and calcination produced. This catalyst allows thenAcylation (especially the acetoxylation) of alkyl-substituted aromaticsn(For example, toluene) especially in the gas phase in high conversionnand high yield (up to 80%) with high space-time yieldnand with a long service life of the catalyst. |
