Applications

Cyclohexylamine is a useful as an intermediate in organic synthesis. It acts as a precursor to prepare pendant-armed dialdehydes, bromohexine HCl and sulfenamide-based reagents. It is widely used in the production of vulcanization accelerators like N-cyclohexyl-2-benzothiazole sulfonamide (CBS) and artificial sweeteners (cyclamates). As a corrosion inhibitor, it is used in the treatment of boiler water and prevents corrosion of metal surfaces that arise due to dissolved carbon dioxide. It is involved as a solvent in the synthesis of an inorganic-organic hybrid semiconductor, ZnS/CHA (CHA = cyclohexylamine) nanocomposites.

Notes

Air and moisture sensitive. Incompatible with strong oxidizing agents, carbon dioxide, sodium hypochlorite, organic acids, mineral acids and peroxides.

Literature References

For protection of an aldehyde as its cyclohexyl imine, see, e.g.: Org. Synth. Coll., 8, 586 (1993). Cyclohexyl imines of aldehydes have found use in the directed aldol synthesis: reaction with a less reactive ketone takes place in preference to self-condensation of the aldehyde. See, e.g.: Org. Synth. Coll., 6, 901 (1988):
