GENERAL DESCRIPTION & APPLICATIONS

Turpentine is a semifluid 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). The stepwise distillation with water and carbonates yields terpenes. The water solubility of turpentine oil is negligible. But it is miscible in absolute alcohol and ether. It boils at about 155 - 185 C and its specific gravity is ranged from 0.86 to 088. It dissolves sulphur, phosphorus and resins. Turpentine is used chiefly as a solvent in paints, vanishes and waxes, and in making camphor, inks and other products. Other uses include waterproofing, manufacturing synthetic resins and rubbers, cleaner or remover of paints and oils, disinfectants and moth repellents, medical soaps, internal medicines, ointments, glazing putty, lubricants for grinding glass, petroleum and ore refinement and fire works.
