Diethanolamine (DEA) pure

Design specification: TU 2423-178-00203335-2007, rev. 1

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

Application: Diethanolamine (DEA) pure is employed in organic synthesis process (for example, for absorption of acid gases and sulphurous compounds), as a reagent in analytical chemistry, for production of emulsors, cleansing agents, cosmetic products.
