Abstract
This invention relates to the continuous production of alkane polyols by the reaction of hydrogen and CO in a homogeneous liquid phase mixture containing a rhodium carbonyl complex catalyst, the mole ratio of H.sub.2 /CO in the reactant gas being above about 0.1, wherein the improvement comprises periodically lowering the H.sub.2 /CO mole ratio in the reactant gas to about 0.1 or less and thereafter increasing the H.sub.2 /CO mole ratio to about its former value.
