Abstract RU 2221776 C2

FIELD: organic chemistry. SUBSTANCE: invention relates to new N,N-dimethyl-N-alkyl-N-[alkoxypoly(ethyleneoxy)carbonylmethyl] ammonium chlorides of the general formula (1) wherein R¹,R² are aliphatic hydrocarbon radical comprising 10-16 carbon atoms; n is an average degree of oxyethylation = 3. Compounds show fungistatic and bactericidal activity and they are addition agents also regulating vasoelastic properties of associated multicomponent petroleum systems. Invention relates also to method for preparing compounds of the formula (1) by interaction of monochloroacetic acid with alkoxypolyethylene glycol of the general formula: R¹O(CH₂CH₂O)_nH wherein R¹ is aliphatic hydrocarbon radical comprising 10-16 carbon atoms. EFFECT: improved preparing method, valuable properties of compounds. 4 cl, 3 tbl, 5 ex
