Cyclohexylamine is an inorganic compound with C6H13N chemical formula .It is a primary aliphatic amine whose structure consists of a cyclohexane with an amino substitution. The appearance of this amine is a Colorless or yellow and colorless liquid. The taste of fish and smells like ammonia (Strong, fishy, amine odor).
Like other amines, it has a weak base compared to strong bases such as NaOH and compared to other analog aromatics such as aniline, it is a strong base.
Flash point 90°F. it is Very soluble in ethanol and miscible in water ,ether , acetone and common organic solvents such as alcohol, ethers, ketones, esters, aliphatic hydrocarbons; completely miscible with aromatic hydrocarbons. It is a strong base.

Production and reactions
There are generally two ways to produce cyclohexylamine. The main method of production of this material is complete hydrogenation of aniline using some cobalt or nickel-based catalysts at elevated temp and pressures.
C6H5NH2 + 3 H2 → C6H11NH2
It is also prepared from the alkylation reaction of ammonia with cyclohexanol.
It is commonly used as a corrosion inhibitor for boiler feed water, and to make other chemicals and insecticides.
other uses of this substances are :
• Buffer or pH regulating agent
• bleaching agents for textiles consumer or industrial use
• adhesives and binding agents
• Corrosion inhibitors and anti-scaling agents
• Ink, toner, and colorant products
• Paints and coatings
• Water treatment products
Cyclohexyl amine is primarily used as an intermediate for the synthesis of many chemicals.
Cyclohexyl amine is also used as a precursor to sulfenamide-based reagents. These materials are used as accelerators for vulcanization. Like other amines, it is a corrosion inhibitor.
It is an alkaline-corrosive agent.
It is Highly flammable. Sensitive to air and light. Decomposes due to heat and emits highly toxic vapors that may be emitted over a considerable distance from the combustion source. Nitrogen is produced by burning toxic oxides. Avoid physical damage and storage with oxidizing agents.
Complications of inhaling cyclohexylamine include: nausea, vomiting, dizziness and irritation of the eyes and respiratory system, skin irritation, mucous membranes, skin burns; Cough skin sensitivity; Drowsiness is the head of diarrhea.
This substance is classified in the group of highly toxic substances. The potentially lethal oral dose is 50-500 mg / kg or between 1 teaspoon to 1 ounce for a 70 kg (150 lb) person.
This compound may be incompatible with isocyanates, halogenated organic matter, peroxides, phenols, epoxides, anhydrides and halide acids.
