制备方法与用途

化学性质

油酸钙又名9-十八碳烯酸钙，化学式为Ca(C18H33O2)2，分子量603.97。它是一种淡黄色晶体或白色蜡状晶体，熔点为83～84℃。该化合物不溶于水、乙醇、乙醚、丙酮及石油醚，但能溶于氯仿和苯等有机溶剂。在140℃以上会分解，并缓慢吸收空气中的水分形成一水合物。

油酸钙由氯化钙溶液与油酸相互作用而制得，主要用于制造干燥剂和颜料等。

生产方法

将50g油酸钠溶于2L水中并加热至90℃。然后滴加由25g氯化钙溶于200mL水中制成的溶液，会产生白色沉淀物。过滤后用蒸馏水洗至无氯离子残留，并在干燥器中抽干。若将此固体在105℃烘箱内加热45min，则会转变为淡黄色、透明的固体。

  The present invention involves a new synthesis route for the formation of lactylates. The method comprises reacting a dilactide with a compound comprising a hydroxy group. This reaction is preferably carried out in the presence of a cation or other source of alkalinity. Preferred compounds comprising a hydroxy group include any fatty acid and fatty acid alcohol (particularly C 1 -C 26 fatty acid chains). Preferred cations include cations of Group I and II metals, with sodium, calcium, and potassium cations being particularly preferred. The inventive reactions proceed much more rapidly than prior art lactylate synthesis reactions, and can be used to form 1-, 2-, 3-, 4-, and 5-lactylates.
