Abstract: Maleic anhydride was prepd. by the oxidn. of butane using a catalyst prepd. from V2O5 and P2O5 activated with Co, Ni or Cd. Thus, a mixt. of V2O5 65.1, HC1 1,000, CoC12.. H2O 32.3, and H3PO4 80.1 parts was refluxed, evapd. to dryness, dried for 12hr at 12≦̸C, and calcined for 4hr. at 350≦̸C. The residue was powdered and mixed with graphite to give a v-p-Co catalyst of ratio 1 ; 1. 14 ; 0. 19.

Abstract: 1475309 Maleic anhydride UCB 1 Aug 1974 [3 Aug 1973] 36943/73 Heading C2C [Also in Division B1] Maleic anhydride is made by the vapour phase oxidation of butane in the presence of an oxidic catalyst comprising phosphorus, vanadium and cobalt and/or nickel. The catalyst may be in a fixed or fluidized bed and have 0À5 to 3 atoms of phosphorus and 0À05 to 0À5 atoms of Group VIII metal per atom of vanadium. The reaction conditions may be 1-4% v butane, 99-96% v air, 350-550‹ C., at least atmospheric pressure and a contact time of 0À5-45.
