摘要
以三异丙醇胺和硼酸为原料,经酯化反应合成三异丙醇胺硼酸酯,并用重结晶方法纯化,制得高纯度的终产物,产物结构通过质谱(MS)、核磁共振氢谱(1 H NMR)、红外光谱(FTIR)等方法表征.研究反应物物质的量比、反应温度、反应时间和共沸溶剂对合成反应的影响以及重结晶溶剂和溶剂比例对纯化效果的影响.结果表明,最优条件下合成的三异丙醇胺硼酸酯的质量分数为99.8%,收率为87.1%.
Triisopropanolamine borate was synthesized through the esterification of triisopropanolamine and boric acid, and purified by recrystallization. The structure of triisopropanolamine borate was characterized by MS, 1H NMR and FTIR. Effects of raw material ratio, reaction temperature, reaction time, and reaction solvent on the synthesis, and those of recrystallization solvent and solvent ratio on the purification were investigated. The product was obtained with a purity of 99.8% and a yield of 87.1%, respectively.
