Abstract: 1296690 Demineralizing water ICI AUSTRALIA Ltd 9 Dec 1969 [20 Dec 1968] 60024/69 Heading C1C [Also in Divisions C2 and C3] The demineralization of water is accomplished by using a mixed bed of a weak acid and weak base type ion exchange resins, in which process the mixed bed is regenerated by eluting it with water or a saline solution at a temperature exceeding that employed during the adsorption stage, said weak acid having a titration curve at the temperature of the adsorption stage such that some portion of it falls within the area defined by the titration curves of the weak base resin at the temperature of adsorption and elution stages respectively, and said weak base having a titration curve with an almost steady pH value over a major portion of the titration curve, which curve is displaced to a more acid position by elevation of temperature, in which process the weak base resin is a heat-stable polymer of triallylamine, preferably in the form of spherical particles.
