Abstract
Изобретение относится к области защиты металлов от коррозии в воде и может быть использовано для ингибирования коррозии в замкнутых системах стальных трубопроводов. Способ защиты стали от коррозии в воде состоит во введении в коррозионную среду 1-10 г/л танина и 10-30 мл/л водного экстракта ореха, полученного путем экстракции сухих листьев в воде при массовом соотношении (2-4):10 при температуре 70-100°С в течение 1-3 ч, с последующей фильтрацией.
