This is also why distillation isn't sufficient to get 100percent or absolute alcohol. When pressure lowers, the boiling point decreases, and when pressure is higher, the boiling point increases. Different types of alcohol have different boiling points, so this can be used to separate them from each other and from other organic compounds. Isopropyl alcohol is an alcohol with three carbon atoms. For example, ethanol, with a molecular weight (MW) of 46, has a boiling point of 78 C (173 F), whereas propane (MW 44) has a boiling point of 42 C (44 F).
