Beschreibung
Zusammenfassung:	FIELD: steel corrosion protection.SUBSTANCE: invention relates to the field of steel protection against water-oil hydrogen sulfide corrosion and can be used to protect equipment and pipelines from corrosion in contact with hydrogen sulfide-containing media in the oil industry. The method includes adding a nitrogen-containing compound to a hydrogen sulfide-containing medium, while N,N-diallyl-4-[(1-methylbut-2-en-1-yl)oxy]aniline at a concentration of 50-200 mg/l is used as the nitrogen-containing compound.EFFECT: increasing the degree of steel protection up to 90.0-96.2%.1 cl, 1 tbl, 3 ex Изобретение относится к области защиты стали от водно-нефтяной сероводородной коррозии и может быть использовано для защиты от коррозии оборудования и трубопроводов, контактирующих с сероводородсодержащими средами в нефтяной отрасли. Способ включает добавление в сероводородсодержащую среду азотсодержащего соединения, при этом в качестве азотсодержащего соединения используют N,N-диаллил-4-[(1-метилбут-2-ен-1-ил)окси]анилин в концентрации 50-200 мг/л. Технический результат: повышение степени защиты стали до 90,0-96,2 %. 1 табл., 3 пр.
