Physical properties of Trimethylamine

At the room temperature and pressure, trimethylamine is a colorless gas with a density higher than that of air and a critical temperature of 161°C. It is soluble in water, ethanol, and ether.

Chemical properties of Trimethylamine

  • Trimethylamine can react violently with oxidants, anhydrides, and mercury. It can corrode metals such as aluminum, magnesium, zinc, tin, copper, and copper alloys. Its vapor with air can form an explosive mixture, which will burn fiercely and explode in the event of fire or high heat.
  • A gas sensor for detecting fish freshness is achieved by detecting trimethylamine.
  • Trimethylamine can be used as a nucleophile in organic synthesis.
  • Trimethylamine is used for the preparation of disinfectants and natural gas alarms, as analytical reagents, and as organic synthesis materials.
  • Trimethylamine is utilized for the preparation of medicines, pesticides, photo materials, rubber chemicals, explosives, chemical fiber solvents, strong basic anion exchange resins, dye levelling agents, surfactants, and basic dyes.
  • Health hazards: Its main hazard to the human body is the irritating effects on the eyes, nose, throat and respiratory tract. Concentrated trimethylamine aqueous solution can cause severe burning sensation and flushing of the skin. After washing, bleeding spots remain on the skin. Long-term exposure causes dryness and discomfort of eyes, nose, and throat.
