Abstract
1511074 Softening water BENCKISER KNAPSACK GmbH 17 March 1976 10771/76 Heading C1C [Also in Division C2] Diphosphonic acids having the general formula: where R represents a hydrogen atom, a lower alkyl group with 1-3 carbon atoms, a phenyl group, a carboxymethyl group or a hydroxyethyl group; and R' represents a hydroxyalkyl group of the formula where R<SP>3</SP> represents a hydrogen atom. an alkyl group, a carboxyl group or esterified carboxyl group, a carbamoyl group or a 1-hydroxyalkyl group and n is 0 or 1; and R<SP>2</SP> represents a hydrogen atom or an alkyl group, or is the same as R'; and salts thereof with bases, are used (a) as agents for softening water, (b) for complexing multivalent ions in aqueous solutions, and (c) for stabilising the hardness of water by adding them in less than the stoichiometric quantity. They are also useful as constituents of liquid fertilisers which may also contain conventional ingredients.
