distillation under pressure
11Vacuum distillation — At atmospheric pressure, dimethyl sulfoxide boils at 189°C. Under a vacuum, it distills off into the connected receiver at only 70°C. Vacuum distillation is a method of distillation whereby the pressure above the liquid mixture to be distilled is …
12Fractional distillation — is the separation of a mixture into its component parts, or fractions, such as in separating chemical compounds by their boiling point by heating them to a temperature at which several fractions of the compound will evaporate. It is a special… …
