Chemical Properties

Colorless liquid

Chemical Properties

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

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).

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.

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.
