摘要： The invention provides for purifying phosphine oxides which may be prepared in such a manner that iminophosphoranes are reacted with phosphorus oxytrichloride using an aprotic organic solvent with permittivity 2.2 or more at 20°C as a solvent under specical reaction conditions to give a liquid reaction product containing phosphine oxides and aminophosphonium chlorides which are yielded as a by-product at the same time as the phosphine oxides. The above described chlorides are removed from the above described liquid reaction product by the solid-liquid separation process, and the solution having been subjected to the solid-liquid separation process is washed with water.
摘要翻译： 本发明提供了可以以这样的方式制备膦氧化物的方法，该方法使亚氨基正膦与三氯氧磷在20℃下使用介电常数为2.2或更高的非质子有机溶剂作为溶剂在特定反应条件下反应，得到液体反应产物， 膦氧化物和氨基鏻氯化物，它们与氧化膦同时作为副产物产生。 通过固液分离处理从上述液体反应产物中除去上述氯化物，并将经过固液分离处理的溶液用水洗涤。
