A novel process for preparing in a high purity and in a high yield phosphorus compounds having a phosphate-phosphonate bond within one molecule, along with only a small amount of a by-product, without being restricted by the kind of a phosphonate having an alcoholic hydroxyl group which is a raw material, without using a catalyst such as magnesium chloride, but only using a nitrogen-containing basic compound.
一种高纯度、高产率制备磷化合物的新工艺,该磷化合物在一个分子内具有磷酸盐-膦酸盐键,同时只有少量副产物,不受作为原料的具有醇羟基的膦酸盐种类的限制,不使用氯化镁等催化剂,只使用含氮碱性化合物。
