How it is made

Ethanolamines are produced on an industrial scale exclusively by reaction of ethylene oxide with excess ammonia, this excess being considerable in some cases. The reaction of ethylene oxide with ammonia takes place slowly and is accelerated by water. Anhydrous procedures employ a fixed-bed catalyst consisting of an organic ion-exchange resin or thermally more stable acidic inorganic clays or zeolites.

In all conventional processes, reaction takes place in the liquid phase, and the reactor pressure is usually sufficiently large to prevent vaporization of ammonia and ethylene oxide at the reaction temperature. In current procedures, ammonia concentrations in water between 50 and 100%, pressures up to 16 MPa, reaction temperatures up to 150 °C, and an excess up to 40 mol of ammonia per mole of ethylene oxide are used. The reaction is highly exothermic, the enthalpy of reaction is about 125 kJ per mole of ethylene oxide. ... Product distribution of the three ethanolamines can be controlled by appropriate choice of the ammonia:ethylene oxide ratio. A higher diethanolamine or triethanolamine content can also be obtained by recycling monoethanolamine or diethanolamine to the reactor or by treating them with ethylene oxide in a separate unit. ... In all industrial processes, complete conversion to the three ethanolamines, without significant formation of byproducts, is achieved.

Produced along with mono- and diethanolamine by ammonolysis of ethylene oxide.
