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: 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: 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: The present invention provides improved oxidation catalysts containing mixed oxides of vanadium and phosphorus and the method for the preparation thereof, which catalysts are particularly effective in the oxidation of n-butane, nbutenes, 1,3-butadiene or a mixture thereof with molecular oxygen or an oxygen-containing gas in the vapor phase to produce excellent yields of maleic anhydride with very good selectivity. At least one vanadium compound, a substantial portion of which is in the pentavalent state, and at least one phosphorus-containing compound is added to an organic liquid medium capable of reducing at least a portion of the vanadium to a +4 valence state, to form a reaction mixture. Partial reduction of the vanadium is effected in the presence of the phosphorus-containing compound and a highly ordered and uniform mixed vanadium phosphorus oxide-containing catalyst precursor is formed.

Abstract: SYNTHESIS OF MALEIC ANHYDRIDE 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.
