| titleOfInvention | Production of acetate esters from alcohols using rhodium complex catalysts |
| abstract | A process for the production of acetate esters by the catalytic reaction of an alcohol of the formula ROH and carbon monoxide in contact with a homogeneous catalyst system of rhodium metal atom, a phosphorus containing ligand in which there is present at least one oxo (=O) oxygen atom attached to a phosphorus atom or a carbon atom to form a Z group and the <IMAGE> group is located at least one carbon atom removed and preferably from 2-4 carbon atoms removed from the phosphorus atom of the molecules represented by the formulas <IMAGE> (V) or <IMAGE> (VI) and a halogen promoter, under mild reaction conditions, wherein R' is H, aryl, alkaryl, aralkyl or alkyl, and wherein 1 or more of said R' groups can be substituted with a Z group but not more than 3 of said R' groups in the molecule are so substituted; a is an integer from 0-4; b is an integer from 0-3; and Z is P(O)R'R'; -C(O)OR'' or C(O)R'', wherein R'' is R'; and wherein ROH is methanol or a mixture of methanol and at least one higher alcohol. |
