COMPOUNDS OF DIETHERAMINE ADDITION AND METHOD OF THEIR SYNTHESIS Russian patent published in 2002 - IPC

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to compounds of dietheramine addition of the formula: where R₁,R₂,R₃ and R₄ each of C₄-C₂₂ means independently of other -alkyl; Y means a radical of the formula (1b): A₁ where C₂-C₃ means -alkylene; C¹ means asymmetric carbon atom in (R)- or (S)-configuration being if C² is R; C¹ is R; C² is S; C¹ is S and C² is R; m₁ is S then m = 2 and the addition compound can be in the form free base, acid salt of acid or quaternary ammonium salt. Invention relates to also a method of their synthesis by interaction of diaminotetracarboxylic acid with thionyl chloride and alcohol, to the compound addition of dietheramine of the formula (2): where value R₁-R have values indicated above. The synthesized compound can be used as a chelating agent, agent of personal hygiene, for example, deodorizer, soap, shampoo. The compound (1) can be used as a plasticizer for materials made of organic fibers. EFFECT: improved method of synthesis, valuable properties of compounds. 8 cl, 1 tbl
