was prepared as follows. Boric acid (10.3 grams) and glycerol (30.6 grams) were added to a 250 milliliter flask. One hundred fifty milliliters of toluene was then added. The reaction was allowed to proceed overnight at 110° C., and the byproduct water (˜9 grams) was continuously removed from the reaction by azeotropic distillation. The final solution was evaporated to remove toluene under vacuum, and a viscous liquid product (˜30 grams) of diglycerol borate was obtained.
