Hydroxyimino alkylene phosphonic acids for corrosion and scale inhibition in aqeous systems

摘要

This invention relates to the use of iminoalkylenephosphonic acids to prevent corrosion, including both localized corrosion and general corrosion on iron based metal surfaces in contact with a corrosive system water in an aqueous system. The invention also relates to the use of the iminoalkylenephosphonic acids to control formation, deposition and adherence of scale at the surfaces of metals in contact with a scale-forming system water in an aqueous system.
