N-[ALKOXYPOLY(ETHYLENEOXY)CARBONYLMETHYL]- AMMONIUM CHLORIDES ELICITING ADDITION AGENT PROPERTY REGULATING VISCOELASTIC PROPERTY OF ASSOCIATED MULTICOMPONENT PETROLEUM SYSTEM, METHOD FOR THEIR PREPARING AND APPLICATION Russian patent published in 2004 - IPC

Abstract RU 2221775 C2

FIELD: organic chemistry. SUBSTANCE: invention relates to new N-[alkoxy-poly(ethyleneoxy)carbonylmethyl] ammonium chlorides of the general formula (1) wherein R is aliphatic hydrocarbon radical comprising 12-16 carbon atoms; n is an average degree of oxyethylation = 3-4; R¹=R² is -CH₂CH₂OH; R³ represents group of the formula (2) wherein R⁴ is aliphatic hydrocarbon radical comprising 15-25 carbon atoms. Compounds show addition agents properties regulating viscoelastic properties of associated multicomponent petroleum systems. Invention relates also to method for preparing compounds of the formula (1) and to method for regulating viscoelastic properties of associated multicomponent petroleum systems by addition of an addition agent as 5-25% solution of compounds of the formula (1). Compounds can be used in petroleum and petrochemical industry. EFFECT: valuable properties of compounds. 4 cl, 1 tbl, 3 ex
