Procedure

Approximately 150 grams of the above dihydroxymethyl oxazoline, 40 grams of boric acid and 100 grams of toluene were heated in a reactor equipped as described above to 160° C. (320° F.) until water evolution during azeotropic distillation ceased. The solvent was vacuum topped at 160° C. (320° F.) to remove solvent and filtered at 100°-110° C. (212°-230° F.) through diatomaceous earth to form an amber-colored oxazoline borate. The product contained approximately 4.9% boron.
