This technique is impossible at the Bancroft point of a system.
This technique is impossible at the Bancroft point of a system. This technique may use either a "pressure swing" or an entrainer, and it is often combined with reflux to increase its efficiency. Many zones of equilibrium known as "theoretical plates" are needed to overcome a small difference in volatility, in this technique's (*) "fractional" type. This procedure fails on a mixture of methanol, acetone, and chloroform, since those three compounds form a "saddle" azeotrope. This technique requires a heat source and a condenser. For 10 points, name this lab technique that separates two substances by boiling one of them off, often used to desalinate water.
