Cycloheptatriene Chemical Properties,Usage,Production
Chemical Properties
Cycloheptatriene is a clear yellow to brownish liquid. Insoluble in water and less dense than water. Vapors heavier than air. Inhalation of high concentrations may have a narcotic effect. It is a ligand in organometallic chemistry and as a building block in organic synthesis. Cycloheptatriene is not aromatic, as reflected by the nonplanarity of the methylene bridge with respect to the other atoms.
Uses
1,3,5-Cycloheptatriene functions as a ligand in organometallic chemistry and also as a building block in organic synthetic processes. 1,3,5-Cycloheptatriene is applied in cycloheptatrienyl transition zirconium complexes formation and in other organic complex formation processes.
Definition
ChEBI: A cycloheptatriene with unsaturation at positions 1, 3 and 5.

General Description
A colorless liquid. Insoluble in water and less dense than water. Flash point 35°F. Vapors heavier than air. Inhalation of high concentrations may have a narcotic effect. Used to make other chemicals.
Air & Water Reactions
Highly flammable. Insoluble in water.
Reactivity Profile
Cycloheptatriene may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. In the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions.
Health Hazard
TOXIC; may be fatal if inhaled, ingested or absorbed through skin. Inhalation or contact with some of these materials will irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
Fire Hazard
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion and poison hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Safety Profile
Poison by ingestion and skin contact. Mutation data reported. A very dangerous fire hazard when exposed to heat, flame, or oxidzers. Potentially violent reaction with nitrogen monoxide. Whenheated to decomposition it emits acrid smoke and fumes.
Purification Methods
Wash the triene with alkali, then fractionally distil it. Store it under N2 or Ar as it resinifies in air. [Dryden J Am Chem Soc 76 2814 1954, Kohler et al. J Am Chem Soc 61 1057 1939, Beilstein 5 IV 280.]
