硼酸三甲酯

低压下吸收峰高与硼酸三甲酯压力成正比，与MgO含量成正比。

Under low pressure , the intensities of the peaks are proportional to the pressure of BATE and to the amount of MgO .

结果利用气相色谱、色谱-质谱联用、红外光谱等分析表征手段，鉴定反应产物确实是硼酸三甲酯。

By means of gas chromatography , mass spectrometry and IR spectrum , the product was confirmed to be trimethyl borate .
