| 摘要 |
This invention is concerned with improving the manufacture of aikanols containing 1 to 2 carbon atoms, especially ethylene glycol and methanol, or carboxylate derivatives thereof from the reaction of hydrogen and carbon monoxide, by a homogeneous catalytic process using as the catalyst a solubilized ruthenium carbonyl compound and a rhodium carbonyl compound by maintaining the concentration of ethylene glycol or carboxylate derivatives thereof in the reaction medium at less than about 30 weight percent. In a preferred embodiment, a continuous process is operated in such a manner that ethylene glycol or carboxylate derivatives thereof is removed from the reactor so as to maintain the total concentration in the reaction medium at less than about 30 weight percent. The net effect is that the overall efficiency of the reaction to the production of ethylene glycol is more favorable. |
