Why is steam distillation used for eugenol?

Why do we use steam distillation to isolate eugenol rather than purify it by simple distillation? Instead, steam distillation lowers the boiling point of the compound to around 100 degrees Celsius since the initial mixture is heterogeneous (two immiscible liquids).

In respect to this, why is steam distillation used to isolate eugenol from cloves?

Steam distillation is used to isolate organic compounds that are immiscible liquids with water and have reasonably high vapor pressure at the boiling water temperature. This week we will use steam distillation to isolate clove oil (eugenol) from cloves and determine how effective the technique is.

Similarly, what is eugenol used for? Eugenol is used in perfumes, flavorings, and essential oils. It is also used as a local antiseptic and anaesthetic. Eugenol can be combined with zinc oxide to form zinc oxide eugenol which has restorative and prosthodontic applications in dentistry.

Also, why is steam distillation used with limonene instead of a simple distillation?

The advantage of steam distillation over simple distillation is that the lower boiling point reduces decomposition of temperature-sensitive compounds. Steam distillation is useful for the purification of organic compounds, although vacuum distillation is more common. When organics are distilled, the vapor is condensed.

How did you isolate the eugenol from pentane?

The sample of pentane, eugenol, and sodium sulfate is run through a drying vent which will separate the solid sodium sulfate and water from the pentane and eugenol. Next, the pentane and eugenol needs to be separated by evaporating the pentane which will then leave a solid eugenol.
