Abstract
This invention relates to the manufacture of valuable alcohols containing 1 to 2 carbon atoms, especially glycol and ethanol from the reaction of hydrogen and carbon monoxide, by a homogeneous catalytic process using as a catalyst a solubilized ruthenium carbonyl complex. The invention also encompasses the catalyst formed during the process. A particular desirable embodiment of the invention is the continuous operation thereof in a manner which minimizes inhibition of glycol formation and represses formation of adverse or undesirable glycol byproducts.
