Dipentene Usage And Synthesis

Chemical Properties	colourless or light yellow liquid
Chemical Properties	Dipentene has a pleasant, lemon-like odor free from camphoraceous and turpentine-like notes. Limonene is the most important and widespread terpene; it is known in the d- and l- optically active forms and in the optically inactive dl-form (known as dipentene).
Uses	Dipentene is used for perfuming and to mask odor. It is a chemical constituent of citrus oil.
Preparation	Dipentene may be obtained by steam distillation of citrus peels and pulp resulting from the production of juice and cold pressed oils, or from deterpenation of citrus oils; it is sometimes redistilled.
Aroma threshold values	Detection: 4 to 229 ppb
Taste threshold values	Taste characteristics at 30 ppm: sweet, orange, citrus and terpy.
General Description	A colorless liquid with an odor of lemon. Flash point 113°F. Density about 7.2 lb /gal and insoluble in water. Hence floats on water. Vapors heavier than air. Used as a solvent for rosin, waxes, rubber; as a dispersing agent for oils, resins, paints, lacquers, varnishes, and in floor waxes and furniture polishes.
Air & Water Reactions	Flammable. Insoluble in water.
Reactivity Profile	Cinene may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas.
Health Hazard	Liquid irritates eyes; prolonged contact with skin causes irritation. Ingestion causes irritation of gastrointestinal tract.
Fire Hazard	Behavior in Fire: Containers may explode.
Chemical Reactivity	Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
Contact allergens	Dipentene corresponds to a racemic mixture of d-limonene and l-limonene. Dipentene can be prepared from wood turpentine or by synthesis. It is used as a solvent for waxes, rosin and gums, in printing inks, perfumes, rubber compounds, paints, enamels, and lacquers. An irritant and sensitizer, dipentene caused contact dermatitis mainly in painters, polishers, and varnishers
Contact allergens	Limonene is a racemic form of dand l-limonene. d-Limonene is contained in Citrus species such as citrus, orange, mandarin, and bergamot. l-Limonene is contained in Pinus pinea. The racemic form (dand l-limonene) is also named dipentene.
