Raschig rings in packed beds are sometimes used in this procedure, as are Vigreux columns.
Raschig rings in packed beds are sometimes used in this procedure, as are Vigreux columns. The Perkin triangle is used in air-sensitive applications, and the pressure-swing type uses extreme positive and negative pressures. Another type can be performed in a bubble-capped column. Governed by Raoult's law, special techniques must be employed for mixtures of water and ethanol or other positive azeotropes because they are move volatile than each of their components individually. One type used to separate hydrocarbons in crude oil is called "fractional". For 10 points, name this method of separate mixtures by boiling them.
