Product Description
Amietol M11 (MMEA) is a clear hygroscopic liquid with an amine-like odor. The freshly distilled product is colorless, but prolonged storage may cause a yellowish discoloration.

Principal applications for Amietol M11 include:

  • Precursor for detergents, fabric softeners
  • Additive for coatings and resins
  • Component for gas sweetening solutions
  • Additive for optical brighteners
  • Fine chemicals, pharmaceuticals

Physical & chemical behavior
Amietol® M11 (MMEA) is miscible in all proportions with water. It is also soluble in most organic solvents.

Chemically it behaves as both a secondary amine and an alcohol. Neutralisation of the amino function by acids results in salt formation.

The product is relatively stable at elevated temperatures but must be kept away from oxidants and acids.

  • Bulk
  • Steel drums (195 kg net)
  • IBC containers (945 kg net)


Carbon steel is adequate for storage of MMEA.

Stainless AISI 316 L is preferable if color stability is to be maintained over long periods.

Copper and copper alloys should be avoided.

For bulk storage a nitrogen atmosphere is necessary to prevent the absorption of moisture and discoloration.
