    Abstract: Unsaturated aldehyde and acid were manufd. by using 2 types of catalysts and controlling oxidation temp. in the fixed bed reactor. The first catalyst consists of partially porous inert supports and coated catalyst adhered to the outer surface of the supports, the second catalyst composed of catalyst materials. The first catalyst was reacted with reactants in the fixed bed reactor tube, and then the second catalyst was reacted with reactants. By above method, propylene or isobutylene were reacted with oxygen mixture in fixed bed to give the corresponding aldehyde or acid.

    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.

    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: 1,126,617. Unsaturated aldehydes and nitriles. STANDARD OIL CO. 14 Oct., 1965 [4 Nov., 1964], No. 43643/65. Heading C2C. A process for the production of olefinically unsaturated nitriles and/or olefinically unsaturated aldehydes comprises introducing molecular oxygen into the bottom zone of a reaction enclosure comprising at least two communicating reaction zones at different levels each containing a fluidized solids catalyst capable of catalysing the reaction of olefines with molecular oxygen and optionally ammonia, the zones being separated by at least one foraminous member with at least some openings large enough to allow catalyst passage therethrough and the amount of open area in the foraminous members being at least 7.5 to 50% of the total internal cross-sectional area; introducing into a reaction zone other than that into which the molecular oxygen was introduced : (a) propylene or isobutylene, and, if the product is intended to be a nitrile, (b) ammonia; maintaining an elevated temperature throughout the reaction zones; passing the reactant vapours upwards through the communicating zones containing the fluidized catalyst; and recovering the product produced, the volume of the reaction enclosure upstream of the reaction zone receiving the component (a) and the optional component (b) being from 5 to 75% of the total volume of the enclosure. The catalyst is preferably composed of a mixture of antimony oxide and the oxide of at least one other polyvalent metal, such as uranium, iron, thorium, cerium and manganese. The production of acrylonitrile, methacrylonitrile, acrolein and methacrolein is described.

    Abstract: Improved oxidation catalysts containing mixed oxides of vanadium and phosphorus which catalysts are particularly effective in the oxidation of n-butane, n-butenes, 1,3-butadiene or a mixture thereof with molecular oxygen or an oxygen-containing gas in the vapour phase to produce excellent yields of maleic anhydride with very good selectivity, are prepared by a process in which 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. An oxidation catalyst comprising the mixed oxides of vanadium and phosphorus characterized by an average valence state of vanadium from +3.9 to +4.6, and a phosphorus to vanadium ratio of 1 : 1 to 1.2 : 1, wherein the macrostructure of the catalyst predominantly comprises generally spheroid particles consisting of stacks of integrally associated sheets of catalytic material is also disclosed.

    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.
