A new technique that arises in this experiment is that of steam distillation. When you isolate the clove oil (eugenol and acetyl eugenol) from cloves, you will not have a solution. Instead, you will have two layers.

The process often used in this isolation is called steam distillation. Steam distillation is an important technique that has significant commercial applications. Many compounds, both solids and liquids, are separated from otherwise complex mixtures by taking advantage of their volatility in steam.
