Abstract
Method of manufacturing hard or ester glycerides substantially neutral of the higher fatty acids, characterized in that it comprises the introduction into a boiler or mixing vessel of a mixture of the indicated fatty acids and glycerides heating this mixture at about 450º f. Vacuum about 25 inches of mercury to verify the esterification the subsequent gradual rise in temperature to about 550ºf then increase the vacuum to about 29 inches while maintaining that temperature and distilling off the free fatty acids and recovering the product of the reaction.
