nature : an essential oil. A colorless to dark brown liquid. Special smell. By hydrocarbon mixtures consisting of, containing a large number of pinene (approximately 64% alpha-pinene and 33% β - pinene). Soluble ethanol, ethyl ether, chloroform and other organic solvents. According to materials used and different method, can be divided into : (a) resin turpentine. That is, ordinary turpentine. Steam generated from steaming resin. Transparent, almost colorless. Anhydrous. No precipitation. About density 0.855-0.865. The refractive index of about 1.467-1.475. (2) extract turpentine. From the pine-Mubanggu extraction with organic solvents generated from the processing. Permeability, slightly pale yellow. No objects and water turbidity. The density 0.850-0.864. The refractive index of about 1.461-1.477. (3) dry distillation turpentine. Also at the crude and refined of the two. The crude distillation from coniferous wood (pine-tree trunks cassia seed and cassia seed) and should. Yellow-brown. With little or no water. Rough intensive products from the chemical processing products remove impurities by steam distillation derived. Transparent. Slightly yellowish green. Turpentine used synthetic camphor, borneol so. The industry used paint solvents. The pharmaceutical industry for liniment.
