Process to inhibit scale formation and corrosion caused by manganese in water systems by use of aminophosphonic acids.

摘要

The deposition of manganese in water systems is inhibited by adding to the water a sufficient amount of an organic aminophosphonic acid to inhibit corrosion and scale resulting from undesirable manganese deposition. Said organic aminophosphonic acid is of a specified formula in which the nitrogen and phosphorus are interconnected by an alkylene or substituted alkaline radical.
