Distillation is a method of separating liquids in order to determine the chemical compounds present. Each compound in a liquid mixture has a different volatility. The distillation process vaporizes each of the components and then re-condenses them one by one into liquid form in order to identify them.
There are four main types of laboratory distillation. Kjeldahl distillation is used in sample preparation for Kjeldahl digestion and determination. Petroleum distillation is used as a scale-down model of petroleum-refining systems. Classic distillation uses basic semi-automated or automated units, and spinning band distillation uses a rotating device to recirculate ...
