Abstract

PURPOSE: To obtain methacrolein efficiently even under conditions of small oxygen ratio, by subjecting isobutene to contact oxidation in gaseous phase using a catalyst prepared by combining Mo, Bi, Ni, Cr, Sn and an alkali metal, or additionally Al and/or Zr.
CONSTITUTION: In preparing methacrolein by subjecting isobutene with moleculr oxygen to contact reaction in gaseous phase, a catalyst shown by the formula (Mo)a (Bi)b (Ni)c (Cr)d(Sn)e (X)f (Y)g (O)h (X is Al and/or Zr; Y is Li, Na, or K; when a=10, b=0.1W10, c=0.5W15, d=0.1W10, e=0.1W15, f=0W10, g is a number =1 and not O, h is usually 33W85) is used in the reaction. The catalyst is preferably calcined at 400W700°C for 3W24hr before use.
EFFECT: Even under conditions of small oxygen ratio and high space velocity, high performance is maintained and combustion reactions are suppressed.
