Abstract
A process is described for the production of zirconium carboxylate comprising combining a carboxylate and a zirconium salt within a basic environment of a basic aqueous solution. The carboxylate is provided in an amount sufficient to give a ratio of carboxylate to zirconium equivalents in a range of from about 1.0:1.0 to 1.40:1.0 and the basic environment is provided by a basic salt in an amount sufficient to leave an excess of base after the combination of the zirconium salt and the carboxylate, whereupon the zirconium reacts in one step to form the zirconium carboxylate product.

A process for the production of zirconium carboxylate comprising:
- combining within a basic environment of a basic aqueous solution having a pH less than 13, a zirconium salt and a carboxylate in an amount sufficient to give a mole ratio of carboxylate to zirconium in the range of from 1:1 to about 1.4:1, said basic environment being provided by a basic salt in an amount sufficient to leave a minimum excess of about 0.11 equivalents of base relative to said zirconium salt after the combination of the zirconium salt and the carboxylate, whereupon sad zirconium salt reacts with said carboxylate within the basic environment to form zirconium carboxylate.
