Dicyclohexylamine is a colorless liquid, although commercial samples can appear yellow. 

Dicyclohexylamine has a fishy odor, typical for amines. It is sparingly soluble in water. 

As an amine, Dicyclohexylamine is an organic base and a valuable precursor to other chemicals.

Dicyclohexylamine salts of fatty acids and sulfuric acid have soap and detergent properties beneficial to the printing and textile industries. 

Dicyclohexylamine metal complexes are catalysts in the paint, varnish, and ink industries. 

Several vapor-phase corrosion inhibitors are solid Dicyclohexylamine derivatives. 

These compounds are slightly volatile at average temperatures and are used to protect packaged or stored ferrous metals from atmospheric corrosion. 

Dicyclohexylamine is also used for several other purposes: plasticizers, insecticidal formulations; antioxidants in lubricating oils, fuels, and rubber; and as an extractant. 

Incompatibilities of Dicyclohexylamine: Contact with strong oxidizers can cause fire and explosion hazard

Synthesis

Dicyclohexylamine, as a mixture with cyclohexylamine, is prepared by the catalytic hydrogenation of aniline (phenylamine) with a ruthenium and/or palladium catalyst. 

This method produces mainly cyclohexylamine with little dicyclohexylamine. 

Better results have been reported when the catalyst is applied to support niobic and/or tantalic acid.

Dicyclohexylamine is also obtained by reductive amination of cyclohexanone with ammonia or cyclohexylamine.

Dicyclohexylamine may also be prepared by pressure hydrogenation of diphenylamine using a ruthenium catalyst or by the reaction of cyclohexanone with cyclohexylamine in the presence of a palladium/carbon catalyst under a hydrogen pressure of about 4 mm Hg.

Applications of Dicyclohexylamine:

Dicyclohexylamine has applications that are similar to those of cyclohexylamine, namely the production of:

antioxidants in rubber and plastics

vulcanization accelerators for rubber

corrosion inhibitors in steam pipes and boilers

agrochemicals

textile chemicals

catalysts for flexible polyurethane foams

As an intermediate, it can be used in various industry applications.

DCHA Dicyclohexylamine is used as a vulcanization accelerator. 

Application in lubricants and cutting Industry: 

Dicyclohexylamine functions as a corrosion inhibitor in lubricants and cutting fluids,  

Dicyclohexylamine does not form Nitrosamines when used.

Other applications of DCHA Dicyclohexylamine are, e.g., dyes (as of dye precursor) or the use as a plasticizer.

Dicyclohexylamine is a widely used chemical intermediate. 

Dicyclohexylamine can be used to absorb acidic gases, preserve rubber latex, plasticize casein, and neutralize plant and insect poisons. 

Metal complexes of dicyclohexylamine are catalysts used in the paint, varnish, and ink industries. 

Dicyclohexylamine salts of fatty acids and sulfuric acid have soap and detergent properties used in the printing and textile industries. 

One of the most essential uses of dicyclohexylamine is as a vapor phase corrosion inhibitor. 

Dicyclohexylamine is used to protect packaged or stored ferrous metals from atmospheric corrosion.

Dicyclohexylamine constituted ionic liquid matrices for bacterial analysis in matrix-assisted laser desorption/ionization mass spectrometry. 

It was used to develop a new palladium catalyst for the Suzuki coupling reaction of aryl bromides with boronic acids.

 It was used as an extractant in the determination of gold(III) by dispersive liquid-liquid microextraction and electrothermal atomic absorption spectrometry
