Cyclohexyl mercaptan Usage And Synthesis
  • Chemical PropertiesCLEAR LIQUID
  • Synthesis Reference(s)Tetrahedron Letters, 35, p. 6057, 1994 DOI: 10.1016/0040-4039(94)88074-3
  • General DescriptionA colorless liquid with a strong disagreeable odor. Insoluble in water and less dense than water. Vapors heavier than air. Flash point near 50°F.
  • Air & Water ReactionsHighly flammable. Insoluble in water.
  • Reactivity ProfileCyclohexyl mercaptan is incompatible with the following: Oxidizers, reducing agents, strong acids, alkali metals .
  • Health HazardMay cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may 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 HazardHIGHLY 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 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 ProfilePoison by intravenous route. Moderately toxic by ingestion, subcutaneous, and intramuscular routes. Mildly toxic by skin contact. Human systemic effects by inhalation: conjunctiva irritation and changes in the olfactory and respiratory systems. Has caused damage to kidneys, liver, and blood vessels in experimental animals. Experimental reproductive effects. Human mutation data reported. A severe eye irritant. Narcotic-like action. Flammable when exposed to heat or flame; can react with oxiduing materials. Iptes on contact with chromium trioxide. Violent reaction with HNO3. Incompatible with oxidants. To fight fire, use alcohol foam, foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and fumes. See also ALCOHOLS.
