Beschreibung
Turpentine oil is a kind of fluid isolated from live trees, mainly pines. It consists of terpenes including monoterpenes, alpha-pinene, beta-pinene and some amount of careen, camphene, dipentene, and terpinolene. It can be used as a solvent and as a source of materials for organic synthesis. For its application in solvent, it can be used for thinning oil-based paints that are useful for the manufacturing of varnishes. In organic synthesis, it can be used for the synthesis of fragrant chemical compounds such as camphor, linalool and alpha-terpineol. It can also be used for large-scale synthesis of bundles of aligned carbon nanotubes. It can also be used as natural flavoring agent as food additive. Moreover, it can be used to synthesize pesticide as well as be used to facilitate the endodontic retreatment.
Chemische Eigenschaften
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.
Physikalische Eigenschaften
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.
Verwenden
Oil of turpentine is primarily used as a solvent for industrial applications, such as thinner for paints and varnishes. Preparation of carbon nano-spheres (CNSs) by decomposition of turpentine oil has been reported.
Vorbereitung Methode
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.
Allgemeine Beschreibung
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.
Air & Water Reaktionen
Highly flammable. Insoluble in water.
Reaktivität anzeigen
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.
Health Hazard
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.
Sicherheitsprofil
An experimental poison
by intravenous route. Moderately toxic to
humans by ingestion. Mildly toxic
experimentally by ingestion and inhalation.
Human systemic effects by ingestion and
inhalation: conjunctiva irritation, other
olfactory and eye effects, hallucinations or
distorted perceptions, antipsychotic,
headache, pulmonary, and kidney changes.
A human eye irritant. Irritating to skin and
mucous membranes. Can cause serious
irritation of kidneys. Questionable
carcinogen with experimental tumorigenic
data. A common air contaminant. A very
dangerous fire hazard when exposed to heat
or flame; can react vigorously with oxidizing
materials. Avoid impregnation of
combustibles with turpentine. Keep cool
and ventilated. Spontaneous heating is
possible. Moderate explosion hazard in the
form of vapor when exposed to flame; can
react violently with Ca(OCl)2, Cl2, CrO3, Cr-
(OCl)2, SnCl4, hexachloromelamine,
trichloromelamine. To fight fire, use foam,
CO2, dry chemical. When heated to
decomposition it emits acrid smoke and
irritating fumes.
mögliche Exposition
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.
Carcinogenicity
When turpentine was applied to
the skin, tumor growth was promoted in the rabbit, but not in
the mouse.

Waste disposal
Dissolve or mix the material

state, and local environmental regulations must be
observed.
Vorsichtsmaßnahmen
During handling of turpentine, occupational workers should always use protective clothing, rubber gloves, and face masks to avoid adverse health effects to the skin and respiratory tract.
