METAL CORROSION INHIBITION METHOD

FIELD: metallurgy. ^ SUBSTANCE: method involves addition to water environment of corrosion inhibitor; at that, as corrosion inhibitor there used is 2.6-di-(21-cyclopentene-31-il)aniline with concentration of 25-200 mg/l. Method is implemented in water environments differing as to mineralisation degr...

Beschreibung
Zusammenfassung:	FIELD: metallurgy. ^ SUBSTANCE: method involves addition to water environment of corrosion inhibitor; at that, as corrosion inhibitor there used is 2.6-di-(21-cyclopentene-31-il)aniline with concentration of 25-200 mg/l. Method is implemented in water environments differing as to mineralisation degree. ^ EFFECT: increasing protection degree of metals against corrosion at reduction of inhibitor concentration. ^ 3 cl, 1 tbl, 3 ex Изобретение относится к ингибиторам коррозии и может быть использовано для защиты от коррозии трубопроводов и оборудования, контактирующего со сточными водами, в нефтяной отрасли промышленности. Способ включает добавление в водную среду ингибитора коррозии, при этом в качестве ингибитора коррозии используют 2,6-ди-(21-циклoпeнтeн-31-ил)aнилин с концентрацией 25-200 мг/л. Способ осуществляют в водных средах, различающихся по степени минерализации. Технический результат: повышение степени защиты металлов от коррозии при снижении концентрации ингибитора. 2 з.п. ф-лы, 1 табл., 3 пр.
