Dipentene

Chemical properties

Dipentene is a terpene clear liquid found in various volatile oils such as cardamon, mace, nutmeg , turpentine oil. Dipentene is mainly composed of limonene, beta phellandrene, myrcene and other terpenes. It is used as a solvent for resins, alkyds and waxes and to make paints, enamels, lacquers and polishes.

Occurrence

Found in a very large number of oils, including oils of lemongrass, citronella, palmarosa, cardamon and bergamot, Siberian pine needle oil and several other essential oils including turpentine oils of various origin (Guenther, 1949).

The Uses of Dipentene

Dipentene (Limonene) is a monoterpene olefin having potential applications in polymer and fuel chemistry. It is also widely used as flavoring and fragrance agent. Dipentene (limonene) is a promising green solvent. Kinetics of the reactions of limonene with OH and OD radicals has been investigated in a low pressure flow tube reactor coupled with a quadrupole mass spectrometer.

Preparation

Dipentene is a by-product in the manufacture of terpineol and in various synthetic products made from α-pinene or turpentine oil (Arctander, 1969). Dipentene is mainly composed of terpene hydrocarbons. because of its refreshing pine, lime aroma and low cost, dipentene is mainly used as cost effective ingredient for household products.

Definition

ChEBI: Spermine is a polyazaalkane that is tetradecane in which the carbons at positions 1, 5, 10 and 14 are replaced by nitrogens. Spermine has broad actions on cellular metabolism. It has a role as an antioxidant, an immunosuppressive agent and a fundamental metabolite. It is a polyazaalkane and a tetramine. It is a conjugate base of a spermine(4+).

Flammability and Explosibility

Flammable, but its vapors do not form explosive mixtures with air under normal working temperature conditions.
