Safety Profile
Poison by ingestion and subcutaneous routes. Corrosive. A severe skin and eye irritant. Questionable carcinogen with experimental tumorigenic data. Human mutation data reported. Combustible when exposed to heat or flame; can react with oxidizing materials. To fight fue, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of NOx. See also CYCLOHEXYLAMINE.

Hazard Information

General Description
A colorless liquid with a faint fishlike odor. Less dense than water. May be toxic by ingestion. Severely irritates skin, eyes and mucous membranes. Used to make paints, varnishes and detergents.
Reactivity Profile
DICYCLOHEXYLAMINE(101-83-7) reacts with oxidizing agents. Forms crystalline salts with many N-protected amino acids . Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
Air & Water Reactions
Slightly soluble in water. May be sensitive to air.
Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Potential Exposure
Dicyclohexylamine salts of fatty acids and sulfuric acid have soap and detergent properties useful to the printing and textile industries. Metal complexes of DI-CHA are used as catalysts in the paint, varnish, the ink industries. Several vapor-phase corrosion inhibitors are solid DI-CHA derivatives. These compounds are slightly volatile at normal temperatures and are used to protect packaged or stored ferrous metals from atmospheric corrosion. Dicyclohexylamine is also used for a number of other purposes: plasticizers, insecticidal formulations; antioxidant in lubricating oils, fuels, and rubber; and as an extractant. Incompatibilities: Contact with strong oxidizers can cause fire and explosion hazard
First aid
Skin Contact: Flood all areas of body that have contacted the substance with water. Don’t wait to remove contaminated clothing; do it under the water stream. Use soap to help assure removal. Isolate contaminated clothing when removed to prevent contact by others. Eye Contact: Remove any contact lenses at once. Flush eyes well with copious quantities of water or normal saline for at lest 2030 minutes. Seek medical attention.
Fire Hazard
Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
