Diethanolamine (DEA)

Design specification: TU 2483-151-00203335-2003, rev. 2

Production method: Diethanolamine (DEA) is produced by means of rectification of commercial triethanolamine (TEA).

Application: Diethanolamine (DEA) is applied in organic synthesis process (for example, for absorption of acid gases and sulphurous compounds), as an analytical chemistry reagent, in emulsifier, detergents and cosmetic preparations.
