Preparation of maleic anhydride using a catalyst containing a uranyl ion
Patent
·
OSTI ID:4166891
A process is described for converting benzene, an ethylenically unsaturated aliphatic hydrocarbon having from 4 to 5 carbon atoms per molecule and from 1 to 2 olefinic double bonds, and in which the 4 carbon atom hydrocarbon is unbranched, or a monoethylenically unsaturated straight-chain aldehyde having from 4 to 5 carbon atoms per molecule and wherein the olefinic double bond is in the beta position with respect to the carbonyl group, to maleic anhydride by catalytic oxidation in the presence of a catalyst comprising a uranyl ion, especially uranium phosphate. One preferred form of the catalyst consists of an intimate chemical admixture of vanadium, uranium, phosphorus, and oxygen in which the uranium to phosphorus mole ratio is from 0.2:1 to 2:1, the phosphorus to oxygen mole ratio is from 0.1:1 to 0.35:1; and the vanadium to uranium atomic ratio is from 0.1:1 to 2:1. A method of preparation of the catalyst composition is also disclosed. (auth)
