GOST no data
CAS 141-43-5

Monoethanolamine is a toxic flammable corrosive colorless viscous hygroscopic liquid with an odor similar to ammonia. It is miscible with water, readily soluble in ethanol, methanol, benzene, chloroform, but practically insoluble in aliphatic hydrocarbons. Reaction of monoethanolamine with 48% HBr results in vinylamine.

Production.

Monoethanolamine is produced jointly with diethanolamine and triethanolamine by reacting ethylene oxide with ammonia in the presence of small amounts of water at 90-130°C and pressure 7-10 MPa. Monoethanolamine is isolated from the reaction mixture by rectification.

Uses.

  • for scrubbing acidic gases (e.g. H2S, CO2, SO2) from refinery and natural gas streams and in other industrial chemical processes. Monoethanolamine scrubbing solution is recycled through a regeneration unit which heats the solution from the scrubber unit to release acidic gases into a purer form and returns the regenerated monoethanolamine solution to the scrubber unit again for reuse.
  • as a raw material for detergents, emulsifiers, dispersants, lubricants, fatty acid soaps, concrete additives;
  • as a parent compound for ethylenediamine, N-vinylpyrrolidone and other chemical compounds;
  • in pharmaceutical formulations for buffering or preparation of emulsions;
  • in manufacture of herbicides, cosmetic formulations, pharmaceuticals;
