  • Solid free-flowing phosphonate composition
    Patent number: 7081212
    Abstract: Solid free-flowing compositions of a magnesium salt of bis(hexamethylene)triamino penta(methylenephosphonic) acid are disclosed. The compositions exhibit desirable scale inhibitor properties and can be used in water treatment. In addition, a method of scale control is disclosed using the magnesium phosphonic acids under ambient conditions of relative humidity of at least 30% as can apply under subtropical or tropical conditions of high relative humidity. The preferred molar ratios of magnesium to phosphonic acid are in the range of from 1:1 to 3:1.
