Lab 1: Isolation of essential oils Why did we use steam distillation? - Steam distillation is used for temperaturesensitive compound which is immiscible in water. - In order to boil, the vapor pressure of liquid = vapor pressure of atm. Water and oil are immiscible. Therefore, they both contribute to vapor pressure. As a result, the mixture will start boiling at lower temperature than each of the compound does => we don't want to heat the mixture at the compound boiling point, it...
