Abstract

Vandige oppløsninger av dietylentriaminpenta (metylen-fosfonsyre) med forbedret stabilitet, omfattende minst 20 vekt-% aktivt materiale, og hvor syren er delvis nøytralisert. Foretrukne produkter omfatter fra 55% til 85% fri syre. Produktene oppnås ved nøytralisering av minst 10% og høyst 80% av de utskiftbare hydrogen-atomene med et vannoppløselig kation, fortrinnsvis natrium-, kalium- eller ammoniumioner. Opplsningens fremstilling er beskrevet.De er nyttige som sekvesteringsmidler for metallioner og som kjelesteninhibitorer.
