Gum turpentine Usage And Synthesis


Chemical Properties

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.

Chemical Properties

colourless liquid with paint-like odour

Chemical Properties

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.

Chemical Properties

Turpentine oil is obtained by steam distillation of the oleo-gum-resin. It has a warm, balsamic, refreshing odor of turpentine. The oil must be absolutely free of water to avoid oxidation of α- and β-pinene (approximately 80% of the oil).

Physical properties

Turpentine steam-distilled is a clear, colorless, mobile liquid.

Uses

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

Production Methods

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.

General Description

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 Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

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.

Potential Exposure

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.

Shipping

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

Incompatibilities

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

Waste Disposal

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.

Precautions

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.
