Abstract:
A process for preparing acrolein in the presence of a solid catalyst having a core-shell structure represented in formula 1 by the oxidation of propylene,[BinAaOx][(100-z)%EeFefNigMomOy+z%SiO2]â€ƒâ€ƒ(1) wherein A is at least one element selected from the group consisting of boron, phosphorus, and molybdenum; E is at least one element having the atomic valence of 2; when m is 1, n is 0.001-3, a is 0-3, e is 0-3, f is 0.01-5, g is 0.1-5, and z is 0-90; and x and y are numbers such that the valence requirements of the other elements for Oxygen in the core and shell catalytic phase, respectively, are satisfied.
