Abstract
Изобретение относится к защите металлов от коррозии в воде и может быть использовано для ингибирования коррозии в замкнутых системах стальных трубопроводов.Согласно изобретению, предлагается применение бис(триэтаноламин)-кобальт(II) диизобутирата в качестве ингибитора коррозии стали в воде, при концентрации в коррозионной среде 0,1-1,5 г/л.Технический результат изобретения состоит в снижении скорости коррозии стали в воде.
