Abstract
Abstract This invention relates to the manufacture of such valuable chemicals as polyhydric alcohols, their ether and ester derivatives, oligomers of such alcohols and monohydric alcohols and their ether and ester derivatives by reacting hydrogen and oxides of carbon in the presence of a rhodium carbonyl complex and a trialkanolamine borate.
