CHEM 344 Distillation of liquid mixtures

What is the distillation of a mixture of liquids?
Distillation refers to the selective boiling and subsequent condensation of a component in a liquid mixture.
It is a separation technique that can be used to either increase the concentration of a particular component in the mixture or to obtain (almost) pure components from the mixture.
How does distillation separate mixtures in chemistry?
Distillation is the process of separating the components of a liquid mixture through selective evaporation and condensation.
The basis of separation is the difference in the vapor pressures (volatilities) of the respective components.
How do you distill liquid?
The process of distillation begins with heating a liquid to boiling point.
The liquid evaporates, forming a vapor.
The vapor is then cooled, usually by passing it through pipes or tubes at a lower temperature.
The cooled vapor then condenses, forming a distillate.
The steps of the process are:
Evaporation.
Crude oil is heated until it evaporates.
Crude oil vapour is put into a fractionating column at the bottom and rises upwards.Condensation.
The temperature is highest at the bottom of the column. Collection.
The fractions are collected.
