colourless liquid with paint-like odour

Turpentine is oleorosin extracted from trees of pinus (pinacae). It is a yellowish, opaque, sticky mass with a characteristic odor and taste. It is used extensively in different industries associated with the manufacturing of polishes, grinding fl uids, paint thinners, resins, degreasing solutions, clearing materials, and ink making. The two primary uses of turpentine in industry are as a solvent and as a source of materials for organic synthesis. As a solvent, turpentine is used for thinning oil-based paints for producing varnishes and as a raw material in the chemical industry.

Solvent and thinner for paints, varnishes, polishes. In manufacture of aroma chemicals such as camphor, myrcene, linalool; source of pine oil.

A clear colorless liquid with a characteristic odor. Flash point 90-115°F. Obtained from naphtha-extraction of pine stumps. Less dense than water and insoluble in water. Hence floats on water. Vapors are heavier than air.

Highly flammable. Insoluble in water.

WOOD TURPENTINE reacts with oxidizing agents. Calcium hypochlorite was placed in a turpentine container, thought to be empty. Reaction with the residual turpentine resulted in an explosion within a few minutes [Benson 1967]. Reacts violently with chromic anhydride [Haz. Chem. Data 1967 p. 68]. Reacts with stannic chloride producing heat and sometimes flame [Mellor 7:430 1946-47]. May also react exothermically with reducing agents to produce gaseous hydrogen.

Occupational exposures to turpentine cause adverse health effects on absorption through the skin, lungs, and intestine. The vapor of turpentine causes severe irritation to the nose, eyes, and respiratory system has a whole. Aspiration of liquid turpentine causes direct irritation to the lungs and results in pulmonary edema and hemorrhage. It also causes dermatitis, eczema, and hypersensitivity among occupational workers. Splashing of liquid turpentine in the eyes causes corneal burns. Turpentine is also known to cause skin eruption, irritation to the gastrointestinal tract, kidney and bladder damage, delirium, ataxia, and benign skin tumor.

Turpentines have found wide use as chemical feedstock for the manufacture of floor, furniture, shoe, and automobile polishes; camphor, cleaning materials; inks, putty, mastics, cutting and grinding fluids; paint thinners; resins, and degreasing solutions. Recently, alpha-and beta-pinenes, which can be extracted, have found use as volatile bases for various compounds. The components d-α-pinene and 3-carene, or their hydroperoxides, may be the cause of eczema and toxic effects of turpentine.

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, give plenty of water to drink and get medical attention. Do not induce vomiting. Medical observation is recommended for 24-48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

UN1299 Turpentine, Hazard Class: 3; Labels: 3- Flammable liquid.

Forms an explosive mixture with air. Violent reaction with strong oxidizers, especially chlorine; chromic anhydride; stannic chloride; chromyl chloride.

Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.

Turpentine is the oleoresin from species of Pinus Pinacea trees. The crude oleoresin (gum turpentine) is a yellowish, sticky, opaque mass and the distillate (oil of turpentine) is a colorless, volatile liquid with a characteristic odor. Chemically, it contains: alpha-pinene; betapinene; camphene, monocyclic terpene; and terpene alcohols.

Any of the volatile predominantly terpenic fractions or distillates resulting from the solvent extraction of, gum, collection from, or pulping of softwoods. Composed primarily of C10H16 terpene hydrocarbons: .alpha.-pinene, .beta.-pinene, limonene, 3-carene, camphene. May contain other acyclic, monocyclic, or bicyclic terpenes, oxygenated terpenes, and anethole. Exact composition varies with refining methods and the age, location, and species of the softwood source.

Gum turpentine is the steam-volatile fraction of pine tree pitch.Wood turpentine is obtained from waste wood chips or sawdust. Sulfate turpentine is a by-product in paper manufacture.

Flammable

When turpentine was applied to the skin, tumor growth was promoted in the rabbit, but not in the mouse.

Routes and Pathways
Humans can be affected by one of several possible exposure routes, as follows: flavoring agents in candies and chewing gums; manufacture of turpentine oil, gum rosin, and synthetic pine oil; application of insecticides, disinfectants, human and veterinary medicines, ointments, deodorizers, and perfumes; and workers in manufacturing of shoe, stove, furniture, synthetic camphor and menthol, cleaning materials, inks, grinding fluids, and thinners.
Partition Behavior in Water, Sediment, and Soil and Physicochemical Properties
Table 2 shows the physicochemical properties and other behavior of turpentine oil.
Environmental Persistency and Long-Range Transport
Turpentine is completely degradable and also does not represent a hazard to plants treated by wastewater, because of solubility limitations. When it is released into the environment, spills or leaks should be completely cleaned up. Best management practices at facilities are needed in order to reduce the amount of turpentine released to the air during turpentine production.
Turpentine is not classified as an air-polluting substance, according to the US Clean Air Act, because its terpenes are completely degraded by natural processes within a few days depending on its concentration, air temperature, and existence of bacteria. Turpentine is recognized safe for ozone depleting or global warming.
According to the US Occupational Safety and Health Administration (OSHA), exposures to turpentine oil may occur through solvents, industrial coatings, and starting material for other compounds, and during pulp and paper processes. People and hobbyists can be exposed through foods, personal care products, household products, external and internal medications, paints, and varnishes.

Ingestion, inhalation, and skin penetration are three common exposure routes of turpentine, due to its lipophilic properties, leading to easy accumulation in fats. As observed in rats, spleen, kidneys, brain, and peripheral fats are the main sites of local acquisition of turpentine. Liver microsomal epoxide hydrase and uridine diphosphoglucuronosyl transferase activities were elevated during chronic turpentine exposures. Toxicity of turpentine may also be attributed to its degraded compounds. For instance, crude sulfate turpentine is usually converted into methyl mercaptan. The terpene constituents of turpentine (typically unsaturated hydrocarbons) may react with oxidants (ozone) of indoor air to generate strong irritant compounds such as formaldehyde or radicals.
