초록 ▼

A crystalline vanadium (IV) phosphate composition having an intrinsic surface area in excess of 10 square meters per gram is prepared by the reaction of orthophosphoric acid with a vanadium (IV) oxycompound. The vanadium compound is suspended in a suitable hydroxylic organic medium, for example isob

대표청구항 ▼

A process for preparing a catalyst having an intrinsic surface area of at least 10 m2/g which is effective to catalyze the oxidation of a hydrocarbon to maleic anhydride comprising the steps of: (a) heating vanadium pentoxide with a substantially non-corrosive anhydrous organic liquid reducing agent composed of carbon, hydrogen and oxygen which has the following properties; (1) contains no olefinic double bonds, (2) has a carbon atom content in the range from 1 to 20, and (3) is relatively unreactive toward phosphoric acid, to reduce the vanadium of the vanadium pentoxide to a valence between 4.0 and 4.6 and thereby obtain a vanadium-containing feed; (b) contacting an orthophosphoric acid with the vanadium-containing feed to form a heterogeneous reaction mixture of suspended vanadium(IV) phosphate, (c) removing liquid from the heterogeneous mixture to obtain the vanadium(IV) phosphate compound, and (d) calcining the vanadium(IV) phosphate compound to obtain said catalyst.
