Trietanolamine technical

Trietanolamine (nitrilotrietanol) - colorless viscous hydroscopic liquid with specific amine smell, beyond all bounds mixes up with water, we will well dissolve in ethanol, benzene, chloroform, it is bad - in saturated hydrocarbons.
Receiving.

Trietanolamine is received together with monoethanol amine and diethanol amide liquid - phase ammonolysis of ethylene oxide in the presence of small amount of water in one stage at temperature of 90 - 130 °C and pressure of 7 - 10 MPas. The formed mix of ethanolamines, water and ammonia divide rectification. Ratio of mixture of ethanolamines is regulated amount of ammonia, temperature of process and the direction in recycling of one or two ethanolamines.

Application.

as absorbent of "acid" gases (H2S, CO2, SO2, etc. ) in refining processes of process gases at the enterprises of oil processing, gas and chemical industries. Absorbed gas is emitted when heating solution, the regenerated trietanolamine goes to recycling;
as raw materials for receiving emulsifiers, dispergators, stabilizers of foams, washing and cleaners, shampoos, surfactant, etc. ;
in pharmaceutics and cosmetics as buffer substance
