Steam Distillation’s lab report
Steam distillation is a process that is used to separate two or more substances, which are chemically inert, immiscible, and have high boiling points (Antic, 1). The method of steam distillation can be carried out either directly or indirectly. The primary purpose of this experiment is to separate eugenol from cloves. The reason behind choosing the steam distillation method is because it allows the separation of both volatile and non-volatile substances without the need of raising the temperatures above 100c(Antic,1). Oil of cloves is rich in eugenol, which is one of the classes of compounds known as phenols, which requires medium heat during extraction (Antic, 2).
