GENERAL DESCRIPTION AND APPLICATIONS

Turpentine is a semi-fluid substance consisting of two principal components, spirits of turpentine (volatile portion also known as oil of turpentine or turps ) and a type of rosin (nonvolatile portion also known as colophony). Turpentine is exuded from coniferous trees. The crude turpentine is distilled through steam into commercial turpentine, oil of turpentine. The pure turpentine oil is a transparent oily liquid with a penetrating odor and a characteristic taste. Turpentine is not a pure substance but a complex mixture of terpenes, particularly large proportion of pinene (bicyclic monoterpenic hydrocarbon), a compound from which camphor is manufactured. Terpene is a class of naturally occurring unsaturated hydrocarbons whose carbon skeletons are composed exclusively of isoprene C5 units (CH2=C(CH3)-CH=CH2), consisting of five carbon atoms attached to eight hydrogen atoms (C5H8). The stepwise distillation with water and carbonates yields terpenes. The most abundant monoterpene is pinene. There are two isomerers called alpha (or beta) pinene. The alpha form boils at 156-160 C, and of the beta form boils at 164-169C. It is used as solvents for paints, coatings and wax formulations. It is used as an intermediate for resins and for camphor, menthol, campholenic aldehyde and terpineol. It is used as lube-oil additives. Myrcene,one of  the most important chemicals used in the perfumery industry, is obtained from beta-Pinene through pyrolysis.

The term of epoxide indicate three membered cyclic ether (also called oxirane or or alkylene oxide) in which an oxygen atom is joined to each of two carbon atoms that are already bonded to each other. The unhindered oxygen atom carries two unshared pairs of electrons - a structure which favors the formation of coordination complexes and the solvation of cations. Epoxides are formed by some oxidation reactions of alkenes with peracids. alpha-Pinene oxide is used in in fragrance applications.
