turpentine, yellow to brown semifluid oleoresin exuded from the sapwood of pines, firs, and other conifers. It is made up of two principal components, an essential oil essential oils, volatile oils that occur in plants and in general give to the plants their characteristic odors, flavors, or other such properties. Essential oils are found in various parts of the plant body (in the seeds, flowers, bark, or leaves) and are also

They are typically light yellow to dark brown in color; tasteless; odorless or faintly aromatic; translucent or transparent; brittle, fracturing

When pure, it is a colorless, transparent, oily liquid with a penetrating odor and a characteristic taste. It contains a large proportion of pinene, a compound from which camphor is manufactured. Turpentine is obtained in large amounts from several species of pines of the SE United States; its physical properties, e.g., boiling point, depend on its source. It is used chiefly as a solvent and drying agent in paints and varnishes.

turpentine

Any resinous exudate or extract from conifers, especially pines; now also commonly a term for its volatile fraction, oil (or spirits) of turpentine. Semifluid mixtures of organic compounds consisting of resins dissolved in a volatile oil, turpentines can be distilled (see distillation) into the volatile oil of turpentine and the nonvolatile rosin. The oil, a mixture of monoterpenes (see isoprenoid), chiefly pinene, is a colourless, odorous, flammable liquid that does not mix with water but is a good solvent for many substances. Oil of turpentine is favoured over petroleum solvents as an oil-paint thinner, varnish solvent, and brush cleaner. Its chief use is now as a raw material for resins, insecticides, oil additives, and synthetic pine oil and camphor and as a solvent.

turpentine

1. any of various viscous oleoresins obtained from various coniferous trees, esp from the longleaf pine, and used as the main source of commercial turpentine

2. a brownish-yellow sticky viscous oleoresin that exudes from the terebinth tree

3. a colourless flammable volatile liquid with a pungent odour, distilled from turpentine oleoresin. It is an essential oil containing a mixture of terpenes and is used as a solvent for paints and in medicine as a rubefacient and expectorant

4. any one of a number of thinners for paints and varnishes, consisting of fractions of petroleum
