Abstract
1420014 Treating water with sequestering agents EASTMAN KODAK CO 8 Feb 1973 [8 Feb 1972] 6260/73 Heading C1C [Also in Division G2] The formation of a precipitate in an aqueous solution having dissolved therein sodium and/or potassium ions and, as sequestering agent for a bivalent or trivalent metal ion, a compound of the formula where R is 1-5 C alkyl or an alkali metal, ammonium or ethanolamine salt of the compound or a mono- or di-alkyl ester thereof with methanol, ethanol, propanol or butanol, is inhibited by adding to the aqueous solution at least 0À01 mole of lithium ions per litre of the solution. R is preferably methyl.
