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 for activating fluid bed catalysts useful for producing maleic anhydride from 4 carbon atom hydrocarbons is provided including contacting the fluidized catalyst containing the mixed oxides of vanadium and phosphorus with oxygen and a reducing gas at least partially combustible with oxygen at elevated temperatures sufficient to cause such combustion, wherein the molar ratio of reducing gas to oxygen is below the stoichiometric ratio required for complete combustion of the reducing gas. Also provided are catalysts activated by the process of the invention, as well as a process for producing maleic anhydride utilizing the catalysts thus activated.

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-butanes, 1.3-butadiene of 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 a liquid medium, a mixed phosphorus component comprising orthophosphoric acid and pyrophosphoric acid is added to the liquid 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 mixed phosphorus component, and the resulting vanadium-phosphorus oxide catalyst precursor is recovered, dried and calcined.

Abstract: Vanadium-free catalysts consisting essentially of oxides of titanium and phosphorus have been found to be especially effective in the oxidation of n-butane, n-butenes and 1,3-butadiene with molecular oxygen in the vapor phase to yield maleic anhydride. The reaction with n-butane gives an especially pure product in good yield and selectivity.
