磷酸三丁酯合成路线

详细合成路线

磷酸三丁酯上下游产品

磷酸三丁酯上游产品

磷酸三丁酯下游产品

磷酸三丁酯制备

1.由三氯氧磷(POCl₃)与正丁醇反应制得。

将丁醇加入酯化锅内，冷却至10℃以下，在搅拌下加入三氯氧磷，反应湿度保持在30℃左右，搅拌至反应结束。加水洗涤，静置分去水层，再用10%碳酸钠溶液中和至pH值为7，控制湿度在40℃以下，中和后的粗酯进行减压蒸馏脱醇，再用水洗涤使酸度达到要求，然后减压蒸馏，除去低沸物后收集150-180℃/1.333-0.667kPa 的馏分即得产品。

2.将三氯氧磷慢慢加入正丁醇中，用加压空气搅拌，温度不得超过40℃，加完后搅拌3h，排出氯化氢。

放冷后，加入冷食盐水中，吸去底层，再用冷食盐水洗一次。将洗净的酸性二丁酯加入水中，再用饱和碳酸钠溶液中和至ph值6～7，然后加入食盐水饱和，分出食盐溶液。再加入无水硫酸钠振荡3h，静置过夜，进行减压分馏可得成品。

3.制法：

于装有搅拌器、温度计、回流冷凝器、滴液漏斗的反应瓶中，加入无水正丁醇（2）222g（3.0mol），吡啶260g（3.3mol），无水苯300mL。搅拌下冰盐浴冷却至-5℃，慢慢滴加三氯氧磷153g（1.0mol）。控制反应温度不超过10℃。加完后慢慢加热至回流，并保持在此温度下反应2h。冷却后加入水500mL，以溶剂吡咯盐^①。分出苯层，水洗。无水硫酸钠干燥。减压蒸馏，收集160～162℃/2,0kPa的馏分，得磷酸三正丁酯^②（1）190～200g，收率71%～75%。注：①吡啶盐酸盐溶于水。将水层减压浓缩，而后用氢氧化钠中和，并蒸馏吡啶层，可回收吡啶约50%。②参照上述方法，以正丙醇代替丁醇，可得到如下各种磷酸三烃基酯（表I-9-4）。
