Solid free-flowing phosphonate composition and method of use

   
   

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 phosphionic acid are in the range of from 1:1 to 3:1.

Las composiciones de flujo libre sólidas de una sal del magnesio del ácido del penta(methylenephosphonic) del bis(hexamethylene)triamino se divulgan. Las composiciones exhiben características deseables del inhibidor de la escala y se pueden utilizar en el tratamiento de aguas. Además, un método de control de la escala se divulga usando los ácidos phosphonic del magnesio bajo condiciones ambiente de la humedad relativa de por lo menos el 30% como puede aplicarse bajo condiciones subtropicales o tropicales de la alta humedad relativa. Los cocientes molares preferidos del magnesio al ácido phosphionic están en la gama de a partir la 1:1 a 3:1.
