Abstract
Abstract This invention relates to novel carbonyl mixed metal salts, containing more than one metal and having the formula: M2(TyT''12 y (CO)30)3 wherein M is a trivalent metal cation which is one of aluminum, gallium, iridium, scandium, yttrium, and rhenium, T and T'' are each different metals selected from the group consisting of cobalt, iridium and rhodium, and y may be any whole number between 1 and 11. These compounds are useful catalysts in the reaction between carbon monoxide and hydrogen to produce oxygenated compounds such as methanol, ethylene glycol, glycerine and 1,2-propylene glycol.
