실험 절차

N,N-dibutylethanolamine/triethylene glycol monobutyl ether borate was prepared as follows. Boric acid (10.3 grams), triethylene glycol monobutyl ether (Fluka, 64.1 grams), and N,N-dibutylethanolamine (28.9 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 brownish liquid product (˜90 grams) of N,N-dibutylethanolamine/triethylene glycol monobutyl ether borate was obtained.
