Distillation is easier to understand if we imagine a spesific combination of two liquids, say diethyl ether and ethanol. The boiling details of the two liquids are 36°C and seventy eight°C, respectively. When we boil this mixture, we notice the subsequent: your complete mixture (each compounds) boils, even so the vapor phase is enriched in the mo
