| | Cyclohexyl mercaptan Usage And Synthesis |
| Application | Cyclohexyl mercaptan can be used to prepare dicyclohexyl disulfide. Dicyclohexyl disulfide is the main raw material for the synthetic rubber scorch inhibitor CTP. In high-temperature, high-speed rubber processing, CTP not only prevents scorching of rubber compounds but also has no adverse effects on the vulcanization characteristics and properties of vulcanized rubber, and can improve the storage stability of unvulcanized rubber compounds. | | Chemical Properties | CLEAR LIQUID | | Synthesis Reference(s) | Tetrahedron Letters, 35, p. 6057, 1994 DOI: 10.1016/0040-4039(94)88074-3 | | General Description | A 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 Reactions | Highly flammable. Insoluble in water. | | Reactivity Profile | Cyclohexyl mercaptan is incompatible with the following: Oxidizers, reducing agents, strong acids, alkali metals . | | Health Hazard | May 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 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 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. | | Flammability and Explosibility | Flammable | | Safety Profile | Poison 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.
