Abstract: Maleic anhydride is produced by the oxidation of 1,3-butadiene, n-butylenes, crotonaldehyde and furan with molecular oxygen in the vapor phase in the presence of catalytic oxides of antimony, molybdenum, at least one element selected from the group consisting of niobium, zirconium, titanium and tantalum and optionally a reducing agent capable of reducing at least part of the molybdenum in the catalyst to a valence state below +6 selected from the group consisting of hydrazine hydrate, molybdenum, tungsten, magnesium, aluminum, and nickel. This catalyst may optionally contain one or more elements selected from the group consisting of Li, Ag, Ce, Cd, Co, As, Si, Zn, Ge, Bi, Ru, Pt, U, Al and Ni. Especially desirable yields of maleic anhydride are obtained from 1,3-butadiene in the presence of a catalyst wherein molybdenum metal is used as a reducing agent.

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: PREPARATION OF MALEIC ANHYDRIDE FROM FOUR-CARBON HYDROCARBONS Maleic anhydride is produced by the oxidation of n-butane, n-butenes, 1,3-butadiene with molecular oxygen in the vapor phase in the presence of catalysts containing molybdenum, phosphorus, oxygen and the following components delineated in Groups I to IV: (I) bismuth, copper and a halogen selected from the group consisting of chlorine, bromine or iodine; or (II) arsenic and at least one element selected from the group consisting of Sn, rare earth metal, Zr, Rh, Mn, Re, Ru, Cu, Pb, Zn, Ti, Cr, Nb, Al, Ga and alkaline earth metal; or (III) at least one element selected from the group consisting of As, Rb, Pd, Cd, Cs, Tl and In; or (IV) rubidium, and at least one element selected from the group consisting of Sn, rare earth element, Ni, Zr, Ba, Fe, Rh, Mn, Re, Ru, Co and Cu.

Abstract: Maleic anhydride and acrylic acid are produced by the oxidation of 1,3-butadiene, n-butylenes, crotonaldehyde and furan with molecular oxygen in the vapor phase in the presence of a catalytic oxide of antimony, molybdenum, vanadium and lithium, cerium, or mixture thereof, wherein one element selected from the group consisting of calcium, iron, tungsten, magnesium, aluminum and nickel is optionally added as a reducing agent. The oxidation of 1,3-butadiene in the presence of a catalyst wherein tungsten metal is used as a reducing agent gives especially desirable high yields to maleic anhydride.

Abstract: OXIDATION OF PROPYLENE AND ISOBUTYLENE TO OBTAIN THE CORRESPONDING UNSATURATED ALDEHYDES AND ACIDS Very desirable temperature control in the oxidation of propylene or isobutylene in a fixed-bed, tubular reactor is obtained by using an oxidation catalyst having two physical forms. me first catalyst which initially contacts the reactants is an essentially inert support having a strongly adhering coat of a catalytic material, and the second catalyst that contacts the reactants after contact with the first catalyst consists essentially of the catalytic material.
