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 oxides of carbon and hydrogen in the presence of rhodium carbonyl clusters which possess an infrared spectrum which exhibit three intense wavelength bands between about plus and minus 10 cm.sup.-.sup.1 of about 1868 cm.sup.-.sup.1, about 1838 cm.sup.- .sup.1, and about 1785 cm.sup.-.sup.1.
