Abstract: Catalysts containing the oxides of vanadium, phosphorus and uranium have been found to be especially effective in the oxidation of n-butane, n-butenes and butadiene with molecular oxygen in the vapor phase to yield maleic anhydride. The reaction with n-butane gives an especially pure product in high yield.

Abstract: Oxidn. catalyst YaSbbMocVdZeOx (I) is used for the improved synthesis of maleic anhydride from 1,3-butadiene and molecular oxygen (II) at 250-600 degrees C. In (I), Y is Li and/or Ce; Z is W, Mg, Al or Ni as the metal or its oxide; a and d = 0.01-1.0; b and c = 1-9; e = 0-1; x = a number which satisfies the valence requirements of the other elements present. Improved yields of clean maleic anhydride and a decreased amt. of waste by-prods. are obtd. by using (I). In an example, 1,3-butadiene and air were passed over Lio.1sbMo3Vo.1Ox + W degrees 0.06 in a stainless steel tube. The heating jacket around the tube was at 360-371 degrees C and the contact time was 3.3 secs.

Abstract: Very desirable temperature control and selectivity are obtained in the oxidation of benzene to maleic anhydride using an oxidation catalyst of an essentially inert support of at least 20 microns containing on its outer surface a coating of a catalytically active oxide material or a catalytically active oxide material and an oxide support.

Abstract: A process is provided for the nitrogenation of hydrocarbons, resulting in the production of cyclic imides and nitriles from hydrocarbons contacted with molecular oxygen and a nitrogenating agent, including ammonia or primary amines, in the presence of an oxidation catalyst containing variable valency metal oxides, in the vapor phase at elevated temperature.

Abstract: The present invention provides a process for the preparation of oxidation catalysts containing mixed oxides of vanadium and phosphorus, which catalysts are particularly effective in the oxidation of n-butane, n-butenes, 1,3-butadiene or a mixture thereof with molecular oxygen or an oxygen-containing gas in the vapor phase to produce high yields of maleic anhydride with good selectivity. A vanadium compound is introduced into an olefinic halogenated organic liquid medium, a phosphorus-containing compound is added to the medium, reduction of at least a portion of the vanadium to a +4 valence state is effected either prior to or subsequent to the addition of the phosphorus-containing compound, and the resulting vanadium-phosphorus oxide catalyst precursor is recovered, dried and calcined.
