Corrosion resistant materials and methods of using them

The corrosion of metal surfaces of systems carrying corrosive aqueous liquids is prevented by introducing into the liquid a composition consisting of an aliphatic straight chain amine having 8-22 C atoms, e.g. octadecyl amine, and a non-ionic emulsifying agent, viz., a polyalkylene glycol ether or a...

Beschreibung
Zusammenfassung:	The corrosion of metal surfaces of systems carrying corrosive aqueous liquids is prevented by introducing into the liquid a composition consisting of an aliphatic straight chain amine having 8-22 C atoms, e.g. octadecyl amine, and a non-ionic emulsifying agent, viz., a polyalkylene glycol ether or a condensate of propylene or similar alkylene oxide and a fatty acid amine, or a quaternary ammonium salt of said condensate. The fatty acid used contains 8-20 C atoms, e.g. as obtained from hydrogenated tallow or from coconut oil. The quaternary compound is preferably quaternary MeSO4. The composition is introduced as an aqueous emulsion into the liquid system either continuously or in measured doses.
