Preparation method of propylene oxidation of acrolein

The present invention relates to a method for the oxidation of propylene to acrolein, mainly to solve the problems of the prior art catalysts long-running performance degradation. By the present invention, at least one selected from SiO2 or Al2O3 as the carrier containing the active components represented by the following general formula: Mo12BiaFebNicSbdXeYfZgQqOx, wherein X is selected from Mg, Co, Ca, Be, Cu, Zn, Pb, or Mn at least one; Y is selected from the group Zr, Th or at least one of Ti; Z is selected from K, at least one Rb, Na, Li, Tl or Cs,; Q is La, Ce, Sm or Th at least one, in which the starting material is selected from antimony tartrate, antimony aspect of ammonium solve the problem, can be used for industrial production of propylene oxidation to acrolein.
