1,141,343. Maleic anhydride. BADISCHE ANILIN- & SODA-FABRIK A.G. 4 March, 1966 [5 March, 1965], No. 9505/66. Heading C2C. [Also in Division B1] Benzene or olefinically unsaturated aliphatic hydrocarbons having 4C e.g. butene - 1 or -2 or butadiene are oxidized to maleic anhydride in the presence of a catalyst containing 1-80% V 2 O 5 , 1-40% WO 3 , 0À5-35% P 2 0 5 and 10- 95% TiO 2 the latter serving as catalyst carrier for the other components. The feed hydrocarbon may contain other hydrocarbons e.g. butane or 5 or 6 C saturated or unsaturated. Oxidation is preferably effected using a mixture of oxygen and nitrogen e.g. at 300-500 C. In Examples 1-3 benzene is oxidized to maleic anhydride and in Example 4 a gaseous mixture containing butenes-1 and -2, butane and isobutylene is similarly oxidized.
