Abstract
A catalyst composition for the production of unsaturated aldehydes by the oxidation of the corresponding olefins, and methods of making and using such catalyst compositions. The catalysts of the present invention include compositions of the formula:MoaPdbBicFedX1eX2fX3gOz,wherein X1 is an element selected from Co, Ni, V, Pt, Rh, or mixtures thereof; X2 is an element selected from Al, Ga, Ge, Mn, Nb, Zn, Ag, P, Si, W, or mixtures thereof; X3 is an element selected from K, Mg, Rb, Ca, Sr, Ba, Na, In, or mixtures thereof; a is 1; b is 0<b<0.3; c is 0<c<0.9; d is 0<d<0.9; e is 0<e<0.9; f is 0<f<0.9; g is 0<g<0.3; and z is an integer representing the number of oxygen atoms required to satisfy the valency of Mo, Pd, Bi, Fe, X1, X2, and X3 in the catalyst composition. Using the methods of the present invention, one may effectively oxidize the desired starting materials at relatively high levels of conversion, selectivity, and productivity, and with minimal side products.
