水介质分离法分子式:CAS号:性质:又称水介质分离法。以表面活性剂水溶液为介质的脂肪酸分离方法。脂肪酸混合物先在有刮板表面的冷却器中冷却到形成固体和液体两相的脂肪酸浆料;与含表面活性剂的水溶液混合,表面活性剂使脂肪酸被水湿润:所用的表面活性剂一般是月桂醇硫酸钠。再加入硫酸镁一类的电解质水溶液,经离心分离,所得到轻的油相是液态的不饱和脂肪酸;而较重的固相是饱和脂肪酸。分别将两部分物料加热使脂肪酸与水溶液分开,接着进行真空干燥得到脱水的脂肪酸产品。已实现工业化的有Henkel法和Lipofrac法。亲水化分离法与各种溶剂结晶分离相比,优点是消除了有机溶剂的高费用,且不需防爆条件。但这种技术得到的产品纯度或级别不如溶剂分离法高。例如以牛油脂肪酸为原料采用Henkel法得到固体组分(硬脂酸为主)碘值为10,得率41%;液体组分(油酸为主)碘值为82,得率59%。采用Lipofrac法得到固体组分碘值为22,得率47%;液体组分碘值为96,得率53%。
