Title: Process for purification of hydroformylation reaction products
Inventor: ANDERSON ARNOLD GUSTAV
IPC: C07C45/85
Filed: 1955-08-04
Abstract: The product, comprising an aldehyde and at least one metal carbonyl, obtained by reacting an olefine with hydrogen and carbon monoxide at elevated temperature and a pressure above 105 kg./sq. cm., in the presence of a cobalt catalyst, is passed at a pressure of 1.8 to 35 kg./sq. cm., and a temperature initially below the decomposition temperature of the metal carbonyl with the lowest decomposition temperature through a demetalling zone containing packing material; steam and an inert gas are passed upwardly through this zone, the amount and pressure of the steam being adjusted to heat the hydroformylation product to the decomposition temperature of the metal carbonyl present with the highest decomposition temperature; the demetalled hydroformylation product mixed with water is passed to a separation zone, maintained at the same pressure as that finally existing in the demetalling zone, where the water is removed. Suitable catalysts are, for example, cobalt octanoate and cobalt naphthenate. Carbonyls other than that of cobalt may be present in the reaction product from the hydroformylation zone due to the reaction of metals, e.g. iron, present in the apparatus.  In the example heptene is treated with carbon monoxide and hydrogen in the presence of cobalt octanoate and the product is demetalled according to the process of the invention.
