A process for preparation of a phosphoromonochloridite in high yield, by contacting phosphorus trichloride (PCl3) with an aromatic diol, such as 2,2'-biphenol, in a slurry, which contains a portion of the aromatic diol in solid form and contains a solution phase containing the remaining portion of the aromatic diol and an organic solvent, under reaction conditions sufficient to produce the phosphoromonochloridite. The slurry comprises less than 5 mole percent of a nitrogen base, calculated on total moles of the aromatic diol, and the organic solvent is selected for its low hydrogen chloride solubility.
一种高产率制备磷单氯亚酰胺的方法,通过将三氯化磷(PCl3)与芳香二酚(例如2,2'-联苯酚)在含有一部分固态芳香二酚和含有剩余芳香二酚和有机溶剂的溶液相的混悬液中接触,在足以产生磷单氯亚酰胺的反应条件下。混悬液中含有的氮碱量计算在总芳香二酚的摩尔数上不超过5摩尔%,所选的有机溶剂具有低氯化氢溶解度。
