补充资料：微分萃取
分子式：
CAS号：
性质：在柱式萃取器内进行的一种萃取。简单的萃取柱即一垂直空筒，为了提高传质效果，可在筒内放入各种内部构件，如在筒内放置填料、转盘、搅拌器、脉冲加装置等。操作时，令轻液自柱底进入，重液则自柱顶加入；通常，一种液体为分散相，另一液体为连续相。若以重液为分散相，轻液为连续相时，重液以细小的液滴，分散在连续的轻液内，并缓缓地往下沉降，溶质便在此时发生传递。当然，也可以重液为连续相，轻液为分散相。能否进行微分萃取，取决于轻、重两相液体的密度差，若密度差很大，两相流体的逆向流动非常容易，易于微分萃取；反之，若密度差很小，则此过程就很难进行，甚至不宜采用微分萃取。
