Code information - Oil, Essential (water steam distillation)

Code:
EOWSD

Name:
Oil, Essential (water steam distillation)

Description:
Essential oils are volatile oils characterized by: aromatic-smell; high refractive index (often optically active); low water solubility; liquid and volatile at ambient temperature; oxidize and resinify on exposure to light and air. Distillation involves placing a plant material into a distillation flask and heating externally to release the volatile oils which are collected in a separate container via a vapour pipe which allows for condensation of the steam to occur more efficiently. In water distillation, water is introduced into the distillation flask with the plant material. For steam distillation, a separate vessel boils the water, which is then introduced into the flask via a pipe as steam.
