  • Patent number: 4191701
    Abstract: The process involves the separation of product from a liquid homogeneous mixture obtained from the reaction of oxides of carbon (e.g. CO) and H.sub.2 in a solvent solution containing a rhodium carbonyl complex catalyst. The solution stability of the catalyst is enhanced by volatilizing the product from the mixture while simultaneously maintaining the mixture in contact with CO gas.

  • Patent number: 3940432
    Abstract: This invention is concerned with improving the ethylene glycol production capabilities of the metal carbonyl catalyzed reaction between carbon monoxide and hydrogen by conducting the reaction such that the ethylene glycol concentration in the reaction mixture is less than 5 gram moles per liter, preferably between about 0.4 to 5 gram moles per liter of reaction mixture and the molar formation ratio between ethylene glycol and methanol in the reaction mixture exceeds about 0.3. In a preferred embodiment, a continuous process is operated in such a manner that the concentration of ethylene glycol in the product mixture removed from the reactor is greater than the average concentration of ethylene glycol in the reactor.
