INHIBITOR OF CARBONIC-ACIDIC CORROSION OF STEEL

摘要

FIELD: metallurgy.;SUBSTANCE: invention can be used at protection of pipelines and equipment in oil industry from corrosion. To protect metals in mineralised mediums containing carbon dioxide there is used 4-methyl-2.6-di-(1¹-methyl-2¹-buthenyl)aniline. Degree of protection from corrosion in mineralised mediums comes to 68.0-97.9 %.;EFFECT: upgraded efficiency of protection of metals from corrosion.;1 tbl, 3 ex
