KOMPOSITION OCH FOERFARANDE FOER ATT INHIBERA KORROSION I ETT VATTENLEDNINGSSYSTEM.

摘要

The inhibition of corrosion of metals in water conducting systems by organic aminoalkylenephosphonic acid derivatives is improved by using in combination therewith a manganese compound capable of providing manganese ions. The said aminoalkylenephosphonic acid derivative may also contain other functional groups, eg. carboxylates, quaternary amines, hydroxyalkyl groups and the like.
