加盐精馏 向精馏塔顶连续加入可溶性盐，以改变组分间的相对挥发度，使普通精馏难以分离的液体混合物变得易于分离的一种特殊精馏方法。加盐精馏的原理和萃取精馏相似，只是添加剂用不挥发的可溶性盐。对盐在其中溶解度较大的组分，它的分子与盐分子之间的作用力较大，挥发度降低的程度也较大；反之溶解度较低的组分，挥发度降低的程度也较低。因此，相对挥发度比未加盐时显著增大，从而有利于采用蒸馏的方法予以分离。对一些能够形成恒沸物的溶液，加盐使相对挥发度发生变化，能够使恒沸物的组成改变或消除恒沸物，从而使分离容易进行。 与采用液体溶剂相比,用盐作为添加剂的优点有:①盐是完全不挥发的，易在塔顶得到很纯的产品；②用少量的盐即可取得显著效果；③可缩小设备尺寸和降低热能消耗，过程经济性较高。 例如将乙醇与水的混合液从塔的中部加入（见图），醋酸钾溶于回流液中从塔顶加入。由于醋酸钾的存在，乙醇与水不再能形成恒沸物。于是从塔顶可直接得到纯乙醇，从塔底得到醋酸钾的水溶液。将此水溶液蒸发以回收醋酸钾，供循环使用。 加盐精馏在工业上的应用还不多，因为在连续操作中固体盐的输送和溶解远不如液体方便，有些物系还存在一些具体的技术问题（如易于堵塞设备等）。
