How do you dry essential oil using liquid nitrogen?
An essential oil is a concentrated, hydrophobic liquid containing volatile compounds from plants or artificially manufactured to replicate such compounds.http://wiki.answers.com/wiki/Plant Essential oils are also known as simply as the "oil of" the plant from which they were extracted, such as oil of clove. An "essential oil" is "essential" in the sense that it carries a distinctive scent, or essence, of the plant. Essential oils do not as a group need to have any specific chemical properties in common, beyond conveying characteristic fragrances.Essential oils are generally extracted by distillation although they may also be recovered through expression or solvent extraction.Since they are fairly volatile, they usually have a lower freezing point than water. As such, they can be effectively dried by treating with liquid nitrogen and straining out the frozen water.It can also be used in a reflux with the oil where the heavier materials including solids and water will remain at the bottom and the volatile oils and nitrogen vapor come out the top.

Differences between essential oils and fatty oils?
Essential oils are not truly "oils" at all. They are volatile organic compounds (VOC) made up of thousands of nature's chemicals but because they contain no lipids, they are not technically considered oils--at least nutritionally. A essential oil 'VOC' is a carbon compound that has a high vapor pressure and low water solubility which evaporates at everyday temperatures. The VOCs that we know as bad for our ozone are human made chemicals used and produced in the manufacture of paints, pharmaceuticals and refrigerants. The low water solubility is what gives essential oils its 'oily' appearance. "Ordinary" vegetable oils, on the other hand, contain lipids and that's what makes them "oils". Some vegetable and animal oils contain what scientists call essential fatty acids. These are fatty acids that the body needs but cannot make on its own, hence the term essential. But they should not be confused with the botanical extracts known as essential oils. Vegetable fatty oils generally come from the seed of the plant where essential oils generally come from leaves, roots, bark and stems. Essential oils are oils that are used in aromatherapy. These oils have a therapeutic properties and if use correctly can overcome some health problems.
