Four basic distillation methods are available to the chemist: simple distillation, fractional distillation, vacuum distillation (distillation at reduced pressure), and steam distillation. Simple distillation transfers the volitile contents of one flask into another by distillation.
  • In this experiment, we extract D-Limonene, which is an isomer of Limonene that smells like citrus. Steam distillation is used to extract the d-limonene as it does not denature the structure of the essential oil molecules. The hot steam opens the pockets in which the oils are kept and releases the aromatic molecules from the orange peel.

It also takes place in hydrocarbon recovery from deep vola acidified and redistilled if desired. This can be avoided by employing dry distillation, i.e., distillation without using steam or any gaseous medium as carrier of the fatty acids. Such process was developed by Mills (1942) who employed a combination of dry and flash distillation to recover fatty acids from hydrolyzed fats and oils (Fig. 3).
