英文摘要: Adsorption of boric acid trimethyl ester (BATE) on high-surface-area silica has been studied by FT-IR spectroscopy. It is found that surface hydroxyls remaining after outgassing at high temperatures act as weak basic sites for BATE adsorption. Coordinate interaction of BATE with isolated hydroxyls dominates the adsorption and induces two splitting B-O vibrational bands at 1375 and 1345 cm(-1). In addition, a small amount of BATE reacts with hydrogen-bonded hydroxyls and strained oxygen generated after high-temperature dehydroxylation. (C) 1998 Elsevier Science B.V.
