摘要： A catalytic process for the preparation of acrolein by the vapor phase oxidation of propylene which comprises contacting propylene and oxygen with a catalyst composition comprising a catalyst system of the formula:Mo.sub.a Bi.sub.b Fe.sub.c X.sub.d Ni.sub.e Tl.sub.f P.sub.g O.sub.hwherein X is one or more of Mg, Mn and Co and a, b, c, d, e, f, g and h represent, respectively, the number of atoms wherein a is 12, b is 0.1 to 5, c is 0.1 to 5, d is 0 to 12, e is 0.1 to 12, f is 1 or less but not 0, g is 0 to 5 and h depends on the number of the other atoms and is usually from 36 to 89. Acrolein is produced with the use of said catalyst in a high selectivity and an excellent yield per each pass even at a large space velocity.
