| 摘 要： | 以乙醇胺、磷酸为原料,经酯化反应合成了单乙醇胺磷酸酯。研究了影响反应的因素,优化了反应条件。酯化反应的最优条件为:n(乙醇胺)∶n(磷酸)=1.0∶1.4,回流反应5 h。经减压蒸馏除去溶剂癸烷得粗产品,收率达94.0%。再用90%乙醇纯化得目标产品。回收率95.0%。对目标产品进行熔点测定、元素分析和红外光谱表征,可确认该产品为标题化合物。该产品长期依赖进口,该方法已扩大试验,有待实现工业化。

| Abstract: | Monoethanolamine phosphate was synthesized by ethanolamine and phosphoric acid as raw materials through esterification.Factors influencing the reactions were invesitgated.The experimental conditions were optimized.The optimum conditions of the esterification are described as follows:n(ethanolamine)∶n(phosphoric acid)=1.0∶1.4,refluxed for 5 h,150 mL decane solvent.The product was obtained with a yield of 94.0%.After the product was recrystallized with 90% alcohol,the yield was 95.0%.Then the product was determined by the analysis of elements,IR and melting point.The method has been magnified and industrialized. |
