The terpinenes are a group of isomeric hydrocarbons that are classified as terpenes. They each have the same molecular formula and carbon framework, but they differ in the position of carbon-carbon double bonds. α-Terpinene has been isolated from cardamom and marjoram oils, and from other natural sources. β-Terpinene has no known natural source, but has been prepared synthetically from sabinene. γ-Terpinene and δ-terpinene (also known as terpinolene) are natural and have been isolated from a variety of plant sources.

Production method
1. Tobacco :FC,18.
2. Synthesis: citrus essential oil deterpene product obtained by further vacuum fractionation; Or pinene in turpentine isprepared by isomerization of acid catalyzed by acid.
Use
1. Mainly used to prepare artificial lemon and peppermint essential oils.
2. The separation and purification of terpinene is more difficult, it is not easy to get pure products, and it is rarely used infragrance modulation, generally used as an intermediate of synthetic spices.
