CYCLOHEPTANE Usage And Synthesis
  • Chemical PropertiesClear colourless liquid
  • Physical propertiesClear, oily, flammable liquid with a faint odor resembling cyclohexane, cyclooctane, or gasoline.
  • Synthesis Reference(s)Journal of the American Chemical Society, 95, p. 1669, 1973 DOI: 10.1021/ja00786a057
    Tetrahedron Letters, 17, p. 463, 1976 DOI: 10.1016/S0040-4039(00)77883-X

  • General DescriptionA colorless oily liquid. Insoluble in water and less dense than water. Flash point 60°F. Vapors heavier than air. Inhalation of high concentrations may have a narcotic effect. Used to make other chemicals.
  • Air & Water ReactionsHighly flammable. Insoluble in water.
  • Reactivity ProfileSaturated aliphatic hydrocarbons, such as CYCLOHEPTANE, may be incompatible with strong oxidizing agents like nitric acid. Charring of the hydrocarbon may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles. In other settings, aliphatic saturated hydrocarbons are mostly unreactive. They are not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents.
  • Health HazardMay be harmful by inhalation, ingestion, or skin absorption. May cause eye and skin irritation.
  • Fire HazardSpecial Hazards of Combustion Products: Vapor may travel considerable distance to a source of ignition and flash back. Container explosion may occur under fire conditions. Forms explosive mixures in air.
  • Environmental FateBiological. Cycloheptane may be oxidized by microbes to cycloheptanol, which may oxidize to give cycloheptanone (Dugan, 1972).
    Photolytic. The following rate constants were reported for the reaction of cycloheptane and OH radicals in the atmosphere: 1.31 x 10-12 cm3/molecule?sec at 298 K (Atkinson, 1985) and 1.25 x 10-11 cm3/molecule?sec (Atkinson, 1990).
    Chemical/Physical. Cycloheptane will not hydrolyze because it has no hydrolyzable functional group.
  • Purification MethodsDistil it from sodium using a Vigreux column (p 11), under nitrogen. It is highly flammable. [Bocian & Strauss J Am Chem Soc 99 2866 1977, Ruzicka et al. Helv Chim Acta 28 395 1945, Beilstein 5 H 92, 5 IV 92.]
