Density, boiling point, and use of cyclohexylamine
Cyclohexylamineis a colorless and transparent liquid with a strong fishy and ammonia odor. Flammable. It is soluble in water and can be mixed with general organic solvents such as ethanol, ether, acetone, ethyl acetate, chloroform, heptane, benzene, etc. CHA can evaporate with water vapor. It can absorb carbon dioxide from the air in the Chemicalbook, forming white crystalline carbonates. It forms an azeotrope with water, with a azeotropic point of 96.4 ℃ and a water content of 55.8%. The aqueous solution is alkaline. 0.01% concentration aqueous solution with pH=10.5. Its vapor forms an explosive mixture with air.
