  • Corrosion inhibitor
    Patent number: 4108790
    Abstract: Oxidative corrosion in cooling water systems containing chlorine to prevent bacterial growth is effectively inhibited by the addition of small amounts of a water-soluble polyphosphate and a water-soluble gluconate. Specific examples of salts are sodium hexametaphosphate and sodium gluconate. The combination of a polyphosphate and a gluconate results in a synergistic improvement of corrosion inhibition.
