Abstract: V-P-Zr catalysts having good activity and selectivity and high physical strength for the oxidation of alkanes, cycloalkanes and mixtures rich in them to dicarboxylic acid anhydrides (e.g. maleic anhydride) are prepared by refluxing an aqueous mixture of vanadium pentoxide and lower dialkyl phosphonate, adding a zirconium salt, and then adding phosphoric acid.

Abstract: Process for the selective production of para-substituted benzene derivatives characterized by the formula: ##STR1## where R.sub.1 and R.sub.2 are individually methyl or ethyl by alkylation of a mono alkyl benzene wherein the alkyl substituent contains 1 or 2 carbon atoms, i.e. toluene or ethylbenzene, with a methylating or ethylating agent in the presence of a catalyst comprising the crystalline aluminosilicate zeolite ZSM-23. The products selectively produced are para-xylene, para-ethyltoluene or para-diethylbenzene.
