BIOCIDAL SYNERGETIC COMPOSITION FOR PREVENTING BIOCORROSION

摘要

FIELD: chemistry. ^ SUBSTANCE: invention can be used for preventing biocorrosion of oil-field equipment. The composition contains, mg/l: corrosion inhibitor SXT 1002 50-400 and biocide Katon 893F (2-octylisothiazolin-3-one) 10-300 or Katon LXE (mixture of 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one) 0.1-0.5, or Katon CG (mixture of 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one with magnesium salts) 0.1-0.3. ^ EFFECT: reduced biocorrosive loss and increased ecological safety due to use of non-toxic components and reduced operating concentration of composition as a result of biocidal synergetic effect. ^ 12 tbl, 1 dwg, 7 ex
