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.
Abstract:
A HOMOGENEOUS LIQUID PHASE PROCESS WHICH COMPRISES CONTACTING HYDROGEN CYANIDE AND AN ORGANOSILICON COMPOUND CONTAINING AT LEAST ONE UNSATURATED SUBSTITUENT IN THE PRESENCE OF A ZERO-VALENT NICKEL, PALLADIUM OR PLATINUM COMPLEX, UNDER SUCH CONDITIONS OF TEMPERATURE AND PRESSURE AS TO MAINTAIN A LIQUID PHASE REACTION MIXTURE. IN A PREFERRED EMBODIMENT, EXCESS, NON-REACTIVE LIGAND IS ADDED TO THE RECTION MIXTURE IN SUCH AN AMOUNT THAT THE RATIO OF MOLES OF EXCESS LIGAND (WHICH CAN BE THE SAME AS OR DIFFERENT FROM THE LIGAND IN THE CATALYST COMPLEX) TO MOLES OF HCN IS VARIED WITHIN THE RANGE OF 0.1 TO 1 TO 25 TO 1 IN ORDER TO GREATLY INCREASE THE TURNOVER OF THE CATALYST, I.E., NUMBER OF MOLES OF PRODUCT PER MOLE OF CATALYST.
