用途
使用
β-Pinene is also used in flavor compositions, partly as ingredient in artificial Lemon and Nutmeg oils, partly as component of such type flavors. The concentration in the finished product will be about 15 to 150 ppm. alpha-Pinene has a more balsamic taste, while be~a-Pinene, less suitable for flavors, has a dry-woody character.
一般的な説明
Alpha-pinene appears as 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.
使用用途
α-ピネンは、香料や医薬品の原料として広く使用されている化合物です。合成樟脳・テルピネオール・ペリラルデヒドの原料として用いられています。また、塗料などの溶剤としても利用されています。 また、ピネンの熱分解によって製造されるは、メントール・・ゲラニオール・ネロール・リナロール等の原料です。香料工業において広く用いられています。 α-ピネンとβ-ピネンをカチオン重合することによって生成された各種のテルペン樹脂は、や粘着剤の製造に用いられています。
製法・合成法
調製方法
beta-pinene can be produced 1) by isolation from American Turpentine (minor component). 2) it is also possible to convert alpha-Pinene into bera-isomer.
