[Problem] Catalyst for use in selective reduction of propionaldehyde in acrolein and/or acrylic acid and/or acrylonitrile containing propionaldehyde and/or propionic acid and/or propionitrile at low concentration. In particular, a novel catalyst for selectively reducing propionaldehyde from acrolein containing the propionaldehyde.
[Solution] Catalyst for use in selective reduction of propionaldehyde in acrolein containing the propionaldehyde, characterized in that the catalyst contains Mo as an indispensable component, and at least one element selected from a group comprising P, Si, W, Ti, Zr, V, Nb, Ta, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, In, Tl, Sn, Ag, As, Ge, B, Bi, La, Ba, Sb, Te, Ce, Pb, Mg, K, Rb, Cs and Al.
