Abstract
1,198,882. Acrolein; methacrolein; acrylic acid; methacrylic acid. MONTECATINI EDISON S.p.A. 13 May, 1968 [16 May, 1967], No. 22504/68. Heading C2C. [Also in Division B1] Acrolein and/or acrylic acid, or methacrolein and/or methacrylic acid, is prepared by the vapour phase oxidation of propylene and/or acrolein, or of isobutylene and/or methacrolein, with oxygen in the presence of a catalyst composition comprising (A) a mono-phase system based on molybdenum trioxide, the crystal lattice of which has been altered by inclusion of atoms of a substituent metal Ms in an amount such that the atomic ratio of Ms to Mo is 1 to 9, the metal Ms being manganese, cobalt or nickel, and (B) tellurium, present either as the metal or as a compound thereof in an amount such as to provide from 0À1 to 10% by weight of tellurium metal with respect to the total weight of the mono-phase system and the tellurium metal or tellurium compound. The catalyst composition, which may be in the form either of a fixed bed or of a fluidized bed, optionally may include a small quantity of a salt or oxide of an alkali metal and/or may be supported on a carrier material, for example silica, carborundum or pumice stone. The alkali metal may result from the use of sodium telluride or potassium telluride as the (or part of the) source of tellurium; alternatively, the tellurium may be provided by another telluride, for example Ag 2 Te, Cu 2 Te, Bi 2 Te 3 , MoTe 2 , CoTe 2 , NiTe 2 , AgBiTe 2 or NiMoTe 4 . The oxidation is carried out either at atmospheric pressure or at elevated pressure, for example at from 2 to 10 atmospheres, at a temperature preferably of from 300‹ to 550‹ C. and with a contact time preferably of from 0À05 to 5 seconds, the molar ratio of propylene and/or acrolein, or of isobutylene and/or methacrolein, to oxygen preferably being between 1 to 0À5 and 1 to 3. The oxygen may be supplied in the form of air, pure oxygen or a mixture of air and oxygen. The oxidation may be carried out in the presence of a halogen-containing organic compound, for example allyl chloride or allyl bromide, and/or in the presence of an inert gaseous diluent, for example steam, nitrogen, carbon dioxide, a saturated hydrocarbon such as for example propane, or the oxidation reaction products after removal therefrom of product aldehyde and/or product acid; product aldehyde may be recycled in order to be oxidized further to the corresponding acid.
