Abstract
Water is softened by the addition of phosphonic acids or phosphonates containing at least 2 P atoms in the molecule, e.g. of the formula <FORM:1032378/C1/1> where R is alkyl or aryl prepared in specified manner (see Division C2). In an example a compound of the above formula where R is methyl was found to inhibit the precipitation of CaCO3 when a soda solution is added to hard water. Also, precipitation of Fe3+ ions as ferric hydroxide from water containing Fe3+ ions is chlorinated hydrocarbon, but particularly nitrogen, introduced to the system via conduits 8 may serve (a) to convey the oxide, e.g. silica, introduced from separators or storage bins 12 to the reaction vessel 1 via conduit 11, (b) as carrier for A via conduit 11, (c) as carrier for and to dilute, the steam, preferably 100 g./m.3 gas, via 10 to conduit 11, and (d) after prior heating in 9, as source of part of the heat for the reaction. These may advantageously be combined by heating the gas by burning an oxyhydrogen flame, and using this heated gas to convey the reactants, or, in the absence of inert gas steam alone may serve this purpose. The reaction vessel is a vertical tubular furnace 1, heated internally by electric heating elements 6. The reactants, heated to 200-800 DEG C., ascend in suspension and the treated oxide passes from settling zone 2 to outlet 3, contact with oxygen being avoided before cooling below 200 DEG C. Gases and untreated oxide are continuously removed via 4 to separators 12 for recycling of the oxide.ALSO:Phosphonic acids or salts thereof containing 2 P atoms in the molecule are obtained from mixtures formed by reaction of carboxy type acylating agents with phosphorous acid or by reaction of PCl3 with carboxylic acids, by treating the mixture with C1-C5 alkanols and (a) distilling off the volatile substances formed and, if desired, converting the acids into the salts, or (b) separating the alcoholic layer after addition of aqueous base. The preferred alkanols are methanol and ethanol. Examples are given in which acetic acid, caproic acid, capric acid, palmitic acid, stearic acid and benzoic acid is reacted with PCl3 and in which acetic anhydride or acetyl chloride is reacted with phosphorous acid. The products may be used in water-softening processes (see Division C1).
