| 摘 要： | 以正丁醇和硼酸为原料采用微波辐射法合成硼酸三丁酯,考察了催化剂、带水剂、反应时间和反应温度对反应的影响。通过试验得到适宜工艺条件(试验室)为:硼酸用量为0.10mol、n(正丁醇)/n(硼酸)为5.2(正丁醇兼作带水剂)、m(NaHSO4催化剂)/m(原料总量)为2.2%和微波辐射时间为13.0min。该条件下产品平均收率为87.4%,反应速率(以酯的收率计)约是常规加热法的18～20倍。通过元素和红外光谱分析对产品进行了物性及结构表征。

| Abstract: | Tributyl borate was synthesized by esterification of boric acid with n-butanol under microwave irradiation. The effects of catalyst, water-carrying reagent, reaction time and reaction temperature have been investigated. The optimum condition of reaction has been found: boric acid 6.2 g(0.10 mol), n-butanol 47.4 mL(0.52 mol, also as water-carrying reagent), one hydrated sodium bisulfate as catalyst 1.0 g (2.2% of the total mass of raw materials), microwave irradiation time 13.0 min, the average yield of prod... |
