Abstract

PURPOSE: To obtain acrolein in high yield, by the catalytic reaction of propylene with O2 in a high-temperature vapor phase, in the presence of a durable MO-Te-Sb system having a high catalytic capability and strength even after a long-term use, and containing a specific component.
CONSTITUTION: Propylene is brought into contact in the vapor phase with molecular oxygen, at 280W450°C, for 0.3W20 seconds, at an ordinary pressure, in the presence of a composition of the formula (Y is Nb and/or V; a,b,c,d,e,f, and g are the numbers of valences, and when a is fixed as 12, b is 0.01W5; c is 0.1W10; d is 0.01W5; e is 0.01W5; f is 0.01W10; g is a value determined according to the numbers of valences of the above-mentioned elements except oxygen, usually 36.3W 103,5) as a catalyst, suitably of grain size 30W100μ, and preferablly calcined at 450W700°C for 2W10 hours in preparation.
