    • Disclosed herein are methods for the preparation of a free-flowing, storage-stable fatty acid metal salt product by 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 metals salts; wherein said monovalent metal is potassium; and wherein said divalent metal is selected from the group consisting of calcium, copper, magnesium and zinc. The fatty acid glycerides may be saponified 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-stage product is obtained, or prior to saponification, the fatty acid glycerides may blended with a stabilizing oil that promotes storage stability, or both. Storage stable metal salts of unsaturated fatty acids prepared by the inventive methods are also disclosed.
    • 本文公开了通过形成包含(a)不饱和脂肪酸甘油酯原料的反应性混合物来制备自由流动的储存稳定的脂肪酸金属盐产物的方法; 和(b)约1mol至约3mol的至少一种一价金属氢氧化物或至少一种二价金属氢氧化物; 并将所述混合物加热至所述脂肪酸甘油酯皂化以形成脂肪酸金属盐的温度; 其中所述一价金属是钾; 并且其中所述二价金属选自钙,铜,镁和锌。 脂肪酸甘油酯可以在氧气分压降低的气氛中被皂化,以有效提高储存稳定性,直到获得自由流动的储存阶段产物,或在皂化之前, 脂肪酸甘油酯可以与促进保存稳定性的稳定油或两者混合。 还公开了通过本发明方法制备的不稳定的不饱和脂肪酸的储存稳定金属盐。
