Design specification: TU 2423-168-00203335-2007, rev. 1, 2
Production method: Triethanolamine (TEA) grades A and B are achieved by ammonia oxiethylation, grade "Clarified" is achieved by purified monoethanolamine (MEA) oxiethylation.
Application: Triethanolamine (TEA) is the component of caoutchouc softeners, coolants, perfumery and cosmetics. Triethanolamine (TEA) and highest fatty acids salts are used as detergents, emulsifying and wetting agents and lubricating substance. Triethanolamine (TEA) is used also as absorbent of acid gases, corrosion inhibitor, accessory material in cement production, and as a feed stock for a number of organic synthesis in farmaceutical industry.
|"Clarified"||Grade A||Grade B|

|Mass fraction of triethanolamine (TEA), %, not less||90.0||90.0||85.0|
|Mass fraction of diethanolamine (DEA), % not more||unlimited||9.0||13.0|
|Mass part of monoethanolamine (MEA), % not more||unlimited||1.0||2.0|
|Mass part of water, % not more||1.0||0.5||1.0|
|Density at 20 °С, within the range g/cm3||1.095–1.135||1.095–1.124||1.095–1.135|
Packing, shipping, storage: Triethanolamine (TEA) is filled up into steel barrels.
Triethanolamine (TEA) is transported by carload consignment in covered railway cars as well as in own heated railroad tank cars or leased models of type 15-898, 15-1603.
Triethanolamine (TEA) is stored in hermetically sealed barrels under the shed or in indoor storage facilities at a distance at least 2 meters off the heating devices, as well as in storage reservoir at outdoor sites under inert gas blanket at a temperature range from minus 40 to 80 °С.
Combined storage triethanolamine (TEA) with severe-service or aggressive products especially together with nitric acid or in presence of chlorine, is not allowed.
Guaranteed storage life triethanolamine (TEA) is 3 years from the date of production.
