Abstract
Process for manufacturing solid catalysts, useful for oxidizing olefins containing from 2 to 16 carbon atoms per molecule to the corresponding carbonyl derivatives, comprising the step of impregnating a carrier with a substantially non-aqueous solution, containing at least two components [A] and [B] of the general formulas: EQU [A]=M.sub.1 X.sub.n L.sub.m EQU [B]=M.sub.2 Z.sub.p L'.sub.q wherein M.sub.1 is rhodium or palladium, X and Z are each an anionic group, n and p are integers selected from 1, 2 and 3, m being an integer selected from 1, 2, 3 and 6 or being O, M.sub.2 is a metal selected from iron, copper, manganese and cobalt, q is an integer selected from 1 to 6 or is equal to O and L and L' are each a coordinate selected from water or an organic compound, said impregnation being conducted in the presence of at least one halogen, a halohydric acid or an organic or inorganic halide.
