WebSteam distillation is also used for high boiling point substances that decompose before the boiling point is reached. In this case, instead of using a vacuum, the liquid in question is mixed with another, immiscible liquid. The presence of the second liquid causes both to boil at a temperature lower than the regular boiling points of either liquid.
