Beta Pinene - Overview

β-pinene 3D molecule

Turpentine, also known as resin, is a semi fluid substance obtained from the bark of pine trees. This turpentine consists of two main components: turpentine oil (volatile), and rosin (colophony). The crude turpentine is distillate to get turpentine (a mixture of tarpon and other compounds), among which pinene is the most abundant monoterpene. The pinene has two isomers: alpha pineneand beta Pinene.

Beta pinene, also known as Rosemarel, is an organic compound. It is a colorless oil type liquid with a woody green pine like smell. Beta pinene is the most abundant compound which is released from forest trees. Beta pinene exist as enantiomers in nature and both the enantiomers (Levorotatory and Dextrorotatory) are recognized. Levorotatory is common in European pines and Dextrorotatory in North America. 

Manufacturing Process

The most common and significant industrial process of Beta Pinene is the fractional distillation of Turpentine oil. About 90% of Beta pinene produced worldwide is produced with this approach. The extraction process is refined and terpene is obtained in this process. The terpene obtained in this way is a mixture of hydrocarbon from fractional distillation.

The Uses of Beta Pinene

Soap & Detergent Industry

Geraniol is a popular floral note prepared from beta pinene. This geraniol and its derivate are used in soap and detergent industry to add fragrances. The most common rose fragrances are also an odor of geraniol.

Perfume & Flavor Industry

Beta pinene is used as raw material for the synthesis of synthetic fragrance. They are the most important chemicals in the perfume industry. Beta pinene is also used for the formulation of flavor with tropical and citrus fruits. They are used in flavoring of food, tobacco and many industrial products. 

Pharmaceutical Industry

Beta Pinene is widely used in pharmaceutical industry as body massage oil and treats disease such as Rheumatism. Beta pinene shows the antimicrobial effect against pathogens and moulds. It is used in ointments.

CST (Crude Sulphate Turpentine)

Alpha and beta pinene are the main constituents of turpentine. Distillation is carried out in two steps. Volatility difference of alpha and beta pinene gives good separation of the product.

Turpentine Resins for Adhesive and Tackifiers

Beta pinene is a naturally sticky terpene monomer, but it is modified as turpentine resins by polymerization or hydrogenation which give it more tack, increased adhesion and low strain rate. Turpentine resins are indispensable in the production of adhesives and tackifiers.

Pesticides and Insecticides

Beta pinene is used as Wilt-Pruf. Beta pinene polymer forms film of short chain polymer components and protects plants from wilt. It is also applicable in insecticides. It is used in the production of grandisol and robustadial which are major constituents of grader which is used to protect cotton crops from boll weevil.
