Terpinolene Chemical Properties,Usage,Production

Chemical Properties

Colorless liquid

Chemical Properties

Terpinolene has a pleasant sweet-piney odor with a somewhat sweet, citrus flavor.

Occurrence

Reported found in citrus juices and oils, black currant, guava, papaya, raspberry, various spice and mint oils, tea, passion fruit, litchi, lovage oil, distilled lime peel oil, ginger, nutmeg, pepper, mace, coriander seed, lovage seed, lovage root, myrtle leaf, pimento berry, pimento leaf, winter savory, smaller galanga, Ethiopian or guinea pepper and ashanti pepper.

Uses

Solvent for resins, essential oils; manufacture of synthetic resins, synthetic flavors.

Definition

ChEBI: A p-menthadiene with double bonds at positions 1 and 4(8).

Preparation

By alcoholic sulphuric acid treatment of pinene (Arctander, 1969).

Production Methods

Terpinolene used to be extracted by fractional distillation of wood turpentine. It is now produced bytreatinga-pinene with aqueous H3PO4 at 75 ℃. It is preferable to distill terpinolene under vacuum to minimize the formation of polymeric products at elevated temperatures.

Aroma threshold values

Aroma characteristics at 1%: sweet, fresh, piney citrus with a woody, old lemon peel nuance.

Taste threshold values

Taste characteristics at 2 to 25 ppm: woody, terpy, lemon and lime-like with a slight herbal and floral nuance.

General Description

A water-white to light amber colored liquid. Insoluble in water and less dense than water. Flash point 99°F. Used to make plastics and resins.

Air & Water Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

Terpinolene may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. In the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions.

Hazard

Flammable, moderate fire risk.

Health Hazard

Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.

Flammability and Explosibility

Not classified

Pharmacology

Combinations of terpenes, such as terpinolene, with nonionic surfactants and stabilizers have been patented for use as gallstone solvents. Human cholesterol calculi heated in mixtures containing terpinolene and human bile were dissolved within 1-2 hr (Hisamitsu Pharmaceutical Co., Inc., 1973).

Safety Profile

Mildly toxic by ingestion. A very dangerous fire hazard when exposed to heat or flame. To fight fire, use foam, CO2, dry chemical. Can react with oxidning materials. When heated to decomposition it emits acrid smoke and irritating fumes.
