Chemical Compound, Monoterpenes

The monoterpenes are isolated from their natural sources by distillation of the plant matter with steam. They are volatile oils, less dense than water, and have normal boiling points in the range 150� - 185� C (300� - 365� F). Purification is usually achieved by fractional distillation at reduced pressures or by regeneration from a crystalline derivative. Acyclic monoterpene hydrocarbons
