Abstract
Polyhydric alcohols are prepared by the aldol condensation of an aldehyde having 1 to 3 hydrogens on the alpha-carbon atom with formaldehyde in the presence of sodium carbonate and the subsequent crossed Cannizzaro reaction wherein the aldol condensation product is reacted with additional formaldehyde and sodium carbonate to form a polyhydric alcohol.
