Abstract: 1427389 Maleic anhydride STANDARD OIL CO 18 April 1973 [5 May 1972] 18738/73 Heading C2C [Also in Division B1] Maleic anhydride is produced by oxidizing 1,3-butadiene, n-butenes, crotonaldehyde, furan or a mixture thereof with molecular oxygen at 250-600‹ C. using a catalyst comprising antimony, molybdenum, oxygen, vanadium and/or iron and, optionally, tungsten, magnesium, aluminium and/or nickel in the atomic proportions Sb a Mo b V c Fed Z e O x wherein: Z=W, Mg, Al and/or Ni; a=1-9; b=1-10; c, d, e=0-1 but c + d is greater than zero; and x is a number to satisfy valency requirements. The reaction pressure is usually superatmospheric but may be atmospheric or subatmospheric with a contact time of 1 to 50 sees. The feed may contain diluents, e.g. steam, nitrogen and carbon oxides. An air to reactant ratio of 12 to 20=1 may be employed. The examples describe the use of butadiene as feed to give a maleic anhydride product containing some acrylic acid.

Abstract: Coated catalysts having an inert support material with an outer surface and a coating of active catalyst containing tungsten, vanadium and molybdenum plus optionally one or more of Fe, Mn, Cu, Sn, Sb, Cr, Ce, U, Co, Ni, Zn, Mg or mixture thereof have been found to be especially effective catalysts for the production of unsaturated acids from the corresponding unsaturated aldehydes, for example, acrolein is oxidized to acrylic acid using these catalysts. The catalysts give a very low exotherm, very high single pass yields of the desired acid and reduce the undesirable by-products.

Abstract: Maleic anhydride is produced by the oxidation of n-butane, n-butenes, 1,3-butadiene or mixture thereof with molecular oxygen in the vapor phase in the presence of a catalytic oxide of molybdenum, phosphorus, oxygen, and at least one element selected from the group consisting of As, Rb, Pd, Cd, Cs, Tl and In.

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.
