Abstract

Organic acids, other than polyoxyfatty acids, are converted into esters by the aid of zinc, tin or other metal of the periodic group of which tin is a member. Particular reference is made to the esterification of fatty and resin acids. Fats containing free fatty acids can be neutralized by heating at ordinary or reduced pressure in the presence of tin with the necessary quantity of glycerol or of the mono- or di-glycerides of such acids as caprylic, lauric, myristic, stearic, oleic or erucic acid. According to the example, a mixture of copra oil waste and copra fat acids is heated with glycerine in the presence of tin until the acid value of the fats becomes practically nil, the reaction taking place with exclusion of air first at normal pressure and then under reduced pressure. Reference has been directed by the Comptroller to Specifications 112,624 and 160,840.ALSO:Fats containing free fatty acids are neutralized by heating at ordinary or reduced pressure in the presence of zinc, tin, or other metal of the periodic group of which tin is a member, with the necessary quantity of glycerol or of the mono- or diglycerides of such acids as caprylic, lauric, myristic, stearic, oleic or erucic acid.
