METHOD FOR IMPROVING THE CORROSION BEHAVIOR OF DISINFECTANT SOLUTIONS.

摘要

Phosphonocarboxylic acids, such as phosphonosuccinic acid and especially 2-phosphonobutane-1,2,4-tricarboxylic acid, and aminopolycarboxylic acids, advantageously tetrasodium trimethylene diamine tetracetate or trisodium nitrilotriacetate, are added to aqueous or aqueous solvent-containing disinfectant solutions based on aldehydes and quaternary ammonium compounds for corrosion inhibition and pH-adjustment to 3.5-4.0, respectively. The corrosion inhibiting effect of the two salts is synergistic.
