    摘要： To provide a process for preparing phosphine oxides comprising reacting iminophosphoranes with phosphorus oxytrichloride by which highly purified phosphine oxides can be obtained industrially in a higher yield.
    Specifically, phosphine oxides are 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 special 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, and 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： Poly(alkylene oxide) which does not contain any metallic component and does not leave an odor is prepared simply and efficiently, by a process using a polymerization initiator which does not cause any problems in preparing and handling in the preparation of the polyalkylene oxide by polymerizing an alkylene oxide compound, and does not require special treatment before the initiation of the polymerization. In the process, the alkylene oxide compound is polymerized in the presence of a phosphine oxide compound represented by the formula (1): wherein Rs are the same or different and each represents a hydrocarbon group having 1 to 10 carbon atoms, and x represents an amount of water molecules contained in terms of a molar ratio and is within a range from 0 to 5.0. If desired, the alkylene oxide compound can be polymerized in the presence of said phosphine oxide compound and an active hydrogen compound selected from water or an organic compound having a partial structural formula -OH or -NH-.
