    • A method of providing a durable, corrosion inhibiting film on the surface of copper or copper-­containing metal in contact with a dynamic, aggressive aqueous system having a pH substantially neutral to alkaline which comprises adding in a non-continuous manner a sufficient amount for the purpose of an alkyl benzotriazole having the formula:
      wherein R is a C₃ to C₆ linear alkyl, and permitting contact of the benzotriazole for a time sufficient to provide the film and thereafter discontinuing the feed of the benzotriazole and permitting any residual benzotriazole in the aqueous system to deplete.
    • 与铜或含铜金属的表面上提供耐腐蚀抑制膜的方法,该膜与具有基本上为中性至碱性的中性的pH的动态侵蚀性水性体系接触,该方法包括以非连续方式加入足够量的 具有下式的烷基苯并三唑的目的:其中R是C 3至C 6直链烷基,并允许苯并三唑接触足够的时间以提供该膜,然后停止苯并三唑的进料并允许任何残留的苯并三唑 水体系耗尽。
