Quick Summary

Steam distillation is a process used to separate substances that are immiscible with water and do not react with it. In this method, steam is introduced into the substance to be distilled. The steam supplies heat, causing the substance to evaporate. The vaporized substance then condenses, forming an aqueous distillate that contains the more volatile components. This technique is useful for distilling materials at temperatures lower than their normal boiling points, such as fatty acids and soybean oils. It is also employed in the production of essential oils for perfumes.123

Steam distillation is an alternative method of achieving distillation at temperatures lower than the normal boiling point. It is applicable when the material to be distilled is immiscible (incapable of mixing) and chemically nonreactive with water. Examples of such materials include fatty acids and soybean…

Methods of production
Steam distillation is by far the most common and important method of production, and extraction with cold fat (enfleurage) or hot fat (maceration) is chiefly of historical importance.
