Abstract
PURPOSE: To obtain the titled compound in high yield, by the catalytic reaction of propylene or isobutylene in the high-temperature vapor phase, in the presence of an Mo-Mg-Fe-Bi system containing a specific active ingredient as catalyst, and usable for a long term with a long catalytic life.
CONSTITUTION: Propylene or isobutylene is brought into contact in the vapor phase with molecular oxygen at 310W480°C for 0.3W10sec at atmospheric pressure, in the presence of a composition of the formula (A is alkali metal; X is Ti, Sn, Pb, Zn, Ta or Zr; a-h are the numbers of valences, and when a is fixed at 12, b is 3W 13; c is 0.05W7; d is 0.001W5; e is 0.005W0.5; f is 0.001W2; g is 0W5; h is a value determined according to the number of valence of each above-mentioned element except oxygen, usually 39W81) as a catalyst, to obtain acrolein or methacrolein in high yield. The catalyst of grain size about 20W100μ may be used, and calcined at 550W650°C for 2W10hr in preparation.
