Beschreibung
Zusammenfassung:	FIELD: metallurgy. ^ SUBSTANCE: invention relates to area of metal protection against corrosion in mineralised of trolly medium, including hydrogen sulphide, inhibitors and can be used with protection against corrosion pipelines and equipment in petrolic branch. Method includes addition into mineralised trolly medium corrosion inhibitor, at that in the capacity of corrosion inhibitor it is used N-acetyl-2-(2.3-dihydroxycilopentenyl) aniline with concentration 50-200 mg/l. Level of protection of steel is 87.8-96.0%. ^ EFFECT: increasing of steel protection rating. ^ 1 tbl, 3 ex Изобретение относится к области защиты металлов от коррозии в минерализованных водно-нефтяных средах, содержащих сероводород, ингибиторами и может быть использовано при защите от коррозии трубопроводов и оборудования в нефтяной отрасли. Способ включает добавление в минерализованную водно-нефтяную среду ингибитора коррозии, при этом в качестве ингибитора коррозии используют N-ацетил-2-(2,3-дигидроксициклопентенил)анилин с концентрацией 50-200 мг/л. Технический результат: степень защиты стали составляет 87,8-96,0%. 1 табл.
