• 用途

  樟脳、殺虫剤、溶剤、可塑剤、香料基剤、松根油の製造

• 説明

  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.

• 化学的特性

  liquid with a turpentine odour

• 使用

  α-Pinene was used as standard in headspace solid-phase microextraction-gas chromatographic analysis of volatile compounds in virgin olive oils 1 . It was used in the synthesis of cesium-doped heteropolyacid having potential application in biodiesel synthesis.

• 定義

  ChEBI: A pinene that is bicyclo[3.1.1]hept-2-ene substituted by methyl groups at positions 2, 6 and 6 respectively.

• 調製方法

  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.

• 製造方法

  From turpentine, by distillation.

• 一般的な説明

  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.

• 空気と水の反応

  Highly flammable. Insoluble in water.

• 反応プロフィール

  alpha-Pinene may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release gaseous hydrogen.

• 健康ハザード

  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.

• 火災危険

  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.

• 接触アレルゲン

  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.

• 安全性プロファイル

  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.
