ABSTRACT:
A process is provided for preparing dilute aqueous copper zirconium ammonium carbonate solutions containing less than about 0.5% Cu and 1.5% ZrO.sub.2, having a Cu:Zr atomic ratio within the range from about 0.5:1 to 1:1 and having an enhanced resistance to gelation and the formation of precipitates, upon storage at atmospheric temperatures, which comprises mixing aqueous solutions of ammonium copper carbonate and ammonium zirconyl carbonate in proportions selected to form copper zirconium ammonium carbonate in solution in water in a concentration within the range from about 0.1% to about 0.5% Cu, and an amount sufficient to inhibit gelation and precipitation of a vicinal diol compound having the general formula:
