亚磷酸三丁酯合成路线

亚磷酸三丁酯制备

1.制法：

于装有搅拌器、回流冷凝器、温度计的反应瓶中，加入1-丁醇（2）74g（1.0mol），吡啶79g（1.0mol），干燥的乙醚250mL，冰盐浴冷却，保持在0℃左右，滴加由三氯化磷46g（0.33mol）与30mL乙醚的混合液。加完后继续搅拌反应0.5h。滤出吡啶盐酸盐，滤饼用乙醚洗涤。合并滤液和洗涤液，无水硫酸钠干燥。先蒸出乙醚，而后减压蒸馏，收集105～110℃/67Pa（或122℃/1.6kPa）馏分，得亚磷酸三丁酯（1）75g，收率90%。

^2.制法：

于装有搅拌器、温度计、滴液漏斗、回流冷凝器的反应瓶中，加入无水乙醇（2）138g（3.0mol），苯100mL，搅拌下冰水浴冷至10℃。慢慢滴加新蒸馏过的三氯化磷137g（1.0mol）和100mL苯的混合液，保持反应温度在5～10℃之间，约1h加完。加完后室温搅拌反应3h。于40℃水浴中加热，减压排除氯化氢，再进行减压蒸馏，收集74～75℃/1.87kPa的馏分，得亚磷酸二乙酯^①（2）124g，收率90%。注：①参照上述方法，可以制备如下各种亚磷酸二烷基酯：亚磷酸二甲酯（C2H7O3P）：56～58℃/1.33kPa，收率60%～80%；亚磷酸二丁酯（C8H19O3P）：124～125℃/1.6kPa，收率80%～90%；亚磷酸二异丁酯（C8H19O3P）：106～107℃/1.6kPa，收率80%～90%；亚磷酸二丙酯（C6H15O3P）：91～92℃/1.45kPa；亚磷酸二异丙酯（C6H15O3P）：83～84℃/2.26kPa。
