Abstract:
1. A method for the preparation of a free-flowing, storage-stable fatty acid metal salt product comprising: forming a reactive admixture comprising (a) an unsaturated fatty acid glyceride feedstock and (b) from about 1 mol to about 3 mol of at least one monovalent metal hydroxide or at least one divalent metal hydroxide; and heating the admixture to a temperature at which said fatty acid glycerides saponify to form fatty acid metal salts in an atmosphere in which the partial pressure of oxygen has been reduced by an amount effective to provide an improvement in storage stability until a free-flowing, storage-stable product is obtained; wherein said monovalent metal is potassium; wherein said divalent metal is selected from the group consisting of calcium, copper, magnesium, and zinc; and wherein said heating step comprises preheating said fatty acid feed stock to a temperature from about 177° C. to about 288° C. and said forming step comprises rapidly forming a uniform homogeneous blend of said fatty acid feedstock and said monovalent metal hydroxide or said divalent metal hydroxide at a rate effective to produce an improvement in storage stability in said metal salt product.
