alpha-Pinene Chemical Properties,Uses,Production
Description
Alpha-pinene is the major constituent of turpentine (about 80%). It exists as a levogyre form in European turpentines, and as a dextrogyre form in turpentines found in North America. Sensitization mainly occurs in painters, polishers and varnishers, and in those in the perfume and ceramics industry.
Chemical Properties
liquid with a turpentine odour
Production Methods
α-Pinene occurs naturally in a variety of trees and shrubs, including more than 400 essential oils, and air concentrations near pine forests may reach 500–1200 mg/m3. Total U.S. emission of α-pinene from deciduous and coniferous forests amounts to 6.6 million tons annually. An estimated emission rate of α-pinene from natural sources to the atmosphere is 1.84×10 -10 g/cm3/s.
Preparation
From turpentine, by distillation.
Definition
ChEBI: A pinene that is bicyclo[3.1.1]hept-2-ene substituted by methyl groups at positions 2, 6 and 6 respectively.
General Description
A clear colorless liquid with a turpentine odor. Flash point 91°F. Less dense than water and insoluble in water. Vapors are heavier than air. Used as a solvent.
Air & Water Reactions
Highly flammable. Insoluble in water.
Reactivity Profile
alpha-Pinene may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release gaseous hydrogen.
Health Hazard
Harmful if swallowed, inhaled or absorbed through skin. High concentrations are extremely destructive to mucous membrane and upper respiratory tract, eyes and skin. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.
Fire Hazard
Special Hazards of Combustion Products: Vapor may travel considerable distance to source of ignition and flashback. Container explosion may occur during fire conditions. Forms explosive mixtures in air.
Contact allergens
Alpha-pinene is the major constituent of turpentine (about 80%). It exists in levogyre form in European turpentine and in dextrogyre form in turpentine found in North-Americans. Sensitization occurs mainly in painters, polishers, and varnishers, and in those in the perfume and in the ceramics industry.
Safety Profile
A deadly poison by inhalation. Moderately toxic by ingestion. An eye, mucous membrane, and severe human skin irritant. Flammable liquid. A dangerous fire hazard when exposed to heat, flame, or oxidizing materials. To fight fire, use foam, Co2, dry chemical. Explodes on contact with nitrosyl perchlorate.
