用高效液相色谱法研究亚磷酸二丁酯和顺丁烯二酸二丁酯反应情况,发现极性溶剂有利于反应进行,最佳反应时间为150分钟,并用红外光谱、质谱、核磁共振等测定方法确定了加成产物的结构。
The reaction conditions of dibutyl phosphite and dibutyl maleate were studied by high performance liquid chromatography. It was found that the polar solvent favored the reaction. The optimum reaction time was 150 minutes. The reaction conditions were determined by infrared spectroscopy, mass spectrometry and nuclear magnetic resonance The method determines the structure of the addition product.
