PENTA-{POLY-(ETHYLENEOXY)CARBONYLMETHYL-HETERYLONIUM}-DERIVATIVES OF TRIPHENOLS AND METHOD FOR THEIR PREPARING, METHOD FOR HYDROPHILIZATION OF EPOXY POLYMERS, METALLIC ARTICLE FETTLED BY THIS POLYMER AND METHOD FOR PREVENTION OF PRECIPITATION OF ASPHALT-RESINOUS-PARAFFIN DEPOSITS FROM PETROLEUM

摘要

FIELD: organic chemistry, chemical technology, polymers.;SUBSTANCE: invention relates to a method for synthesis of novel compounds - penta-{[poly-(ethyleneoxy)carbonylmethyl]heterylonium}-derivatives of triphenols of the formula: . Method for synthesis of the claimed compounds involves interaction of monochloroacetic acid with an oxyethylated product of condensation of alkyl-(C_8-C₁₀)-phenol with 4,4-dimethyldioxane-1,3 in the presence of acid catalyst in medium of a boiling organic solvent and azeotropic removing formed water and the following treatment of the synthesized reaction product with heterocyclic amino-compounds at heating in the molar ratio - oxyethylated product : monochloroacetic acid : heterocyclic amino-compound = 1:(5.0-5.5):(5.0-5.5), respectively. Synthesized compounds possess properties of hydrophilizing modifying agents of polymers. Invention proposes a simple method for hydrophilization of epoxy polymers in their synthesis by mixing epoxy resin, a hardening agent and a modifying agent chosen from the claimed compounds in the amount 0.7-1.5 weight%. Fettling metallic articles (pipelines) by these covers increases their exploitation period from 6 months to 23-24 months based on decreasing precipitation of asphalt-resinous-paraffin deposits from petroleum.;EFFECT: improved method of synthesis, improved and valuable properties of polymers.;9 cl, 1 tbl, 11 ex
