<p>The present invention is directed to methods for solubilizing boric acid to produce liquid, boron-containing solutions. In these methods, boric acid is added to a previously formed solution of a metal ion and ligand. The ligand must be capable of both complexing the metal ion and simultaneously coordinating or hydrogen bonding with the boric acid. Preferred metal ions are the transition metals. Preferred ligands are the alkanolamines, polyamines, dialkylaminoalkylamines and alkyldiaminecarboxylic acids and salts thereof. Using the methods of the present invention, stable, clear solutions, preferrably aqueous solutions, containing about 9-11 percent-by-weight or more boron are readily prepared.</p> |
