AdvanSix Cyclohexylamine (MCHA)

AdvanSix Cyclohexylamine (MCHA) is a colorless, flammable liquid with a distinct fishy odor. It demonstrates solubility in water, ethanol, benzene, and ethyl acetate, remaining stable under recommended storage conditions. MCHA is a versatile chemical, serving as a valuable intermediate in the production of various organic compounds. Notably, it plays a crucial role in inhibiting corrosion in boiler feed water and finds application in the manufacturing of insecticides, plasticizers, dry-cleaning soaps, rubber chemicals, dye stuffs, and gas absorbents, making it a versatile and indispensable component across multiple industries.

Storage & Handling

Handling Recommendations
  • Keep containers closed when not in use.
  • Open containers slowly to allow any excess pressure to vent.
  • Keep away from heat, sparks, flame, or other sources of ignition.
  • Protect small containers from physical damage.
  • Use proper electrical grounding and bonding procedures when loading, unloading, and transferring.
  • Use spark-resistant tools.
  • Electrical equipment and circuits in all storage and handling areas must conform to requirements of national electrical code (Articles 500 and 501) for hazardous location.
