Dicyclohexylamine

Dicyclohexylamine is an organic compound that is a secondary amine featuring two cyclohexyl groups. It is a colorless liquid, although like many amines, samples are often yellow due to impurities. It has a strong fishy odor, typical for amines. It is used as a corrosion inhibitor and in the production of other chemicals.

Chemical Properties

Dicyclohexylamine is a secondary amine with the formula (C6H11)2NH. The molecule consists of a nitrogen atom with two substituents, each a cyclohexyl group. It is a colorless liquid, although commercial samples can appear yellow. It has a strong, fishy odor, which is characteristic of amines.

Production

Dicyclohexylamine is produced by the reaction of cyclohexylamine with cyclohexanone in the presence of a catalyst such as sulfuric acid or hydrochloric acid. The reaction is a type of transamination reaction.

Uses

Dicyclohexylamine is used as a corrosion inhibitor in the water treatment industry. It is also used as a building block in the synthesis of other organic compounds, including pharmaceuticals and agrochemicals. In addition, it is used as a solvent for many organic compounds.

Safety

Dicyclohexylamine is a skin and eye irritant. It is harmful if swallowed or inhaled. It is not classified as a carcinogen, but it may cause damage to organs through prolonged or repeated exposure.
