FIELD: organic chemistry, chemical technology. ^ SUBSTANCE: invention proposes new compounds - 4-isononylphenoxypolyethoxyethyl-bis-(2-hydroxyethyl)amine mono- and disodium salts and a method for their preparing. 4-Isononylphenoxypolyethoxyethyl-bis-(2-hydroxyethyl)amine mono- and disodium salts are prepared by interaction of oxyethylated alkylphenol, triethanolamine and sodium hydroxide taken in the mole ratio - (1.0-1.1):1.0:(1.0-2.0), respectively, at temperature 20-80°C for 2-10 h in solvent medium. As a solvent method involves using aliphatic (C2-C3)-alcohols or water taken in the amount 0-70 wt.-%. 4-Isononylphenoxypolyethoxyethyl-bis-(2-hydroxyethyl)amine mono- and disodium salts can be used as surface-active substances in different branches of industry. ^ EFFECT: improved preparing method, valuable technical properties of substances. ^ 6 cl, 3 tbl, 8 ex |
