<p>A process for inhibiting corrosion of metals in contact with aqueous systems is provided by maintaining in contact with metals a corrosion inhibiting composition that contains a compound, e.g. dimers, trimers and resins, containing the quinomethide group represented as follows: This process is applicable to inhibiting corrosion of and scale deposi-tion on many metals, e.g., ferrous and non-ferrous, including mild steel, cast iron, zinc, copper, copper-based alloys and aluminum, which are subject to corrosion and/or scale deposition in circulating water systems.</p> |
