实验过程

Salicylamide/glycerol borate was prepared as follows. Boric acid (10.3 grams), glycerol (15.3 grams), and salicylamide (22.9 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 yellowish resinous product (˜40 grams) of salicylamide/glycerol borate was obtained.
