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.
