distillation separates a mixture of more than two volatile components based on their differing boiling points The mixture is introduced into a distillation column typically equipped with multiple trays or packing materials Heat is applied to the bottom of the column vaporizing the most volatile components The vapor rises through the column while less volatile components condense and are removed from the bottom As the vapor ascends it encounters trays or packing materials facilitating mass transfer and separation 3 Key Principles Relative Volatility The relative volatility of
