  • Water treatment agent
    Patent number: 5606105
    Abstract: Unsaturated compounds which can be dissolved in aqueous based solvents, such as ethylenic or acetylenic carboxylate or alcohols with less than 10 carbon atoms, especially maleic and/or acrylic acid or propargyl alcohol, are reacted with alkali metal phosphite in aqueous solution at neutral or alkaline pH in the presence of free radical initiators such as persulphate to form threshold scale and corrosion inhibitors.
    Type: Grant
    Filed: August 18, 1994
    Date of Patent: February 25, 1997
    Assignee: Albright & Wilson Limited
