Abstract: Catalysts for oxidn. of C4 hydrocarbons to maleic anhydride(I) are prepd. by reducing V(V) compds., heating the aq. product with P(V) compds. at >120oC, drying, and calcining at 250-600oC, preferably in the presence of 0. Thus, 36.37g V2O5, 22.4 g black UOx, and 50 mL H2O are ball-milled 3 h, mixed with 600 mL H2O and 12.26 g W(particle size

Abstract: Maleic anhydride was prepd. by oxydation of n-butane, n-butene, 1,3-butadiene or these compd.'s mixt. with O2 at 250 - 600≦̸C vapor phase in the presence of improved catalyst which was composed of oxide of Ti and P necessarily and didn't comprised Ba. Thus, titanium dioxide 19.98 g, 85.4% phosphoric acid 28.69 g, vanadium pentoxide 84.2 g and distilled water 600 ml were mixed to make slurry. This aq. slurry was refluxed for 2 hr, evapd., dried at 110≦̸C for 12 hr, calcined at 427≦̸C for 2 hr and crushed to 10 - 30 mesh to give Til.OP1.0-Ox useful catalyst.

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.

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.
