A method of making a phosphono-phosphate compound is disclosed. The method involves a first step of mixing a first component comprising a phosphonic acid, a phosphonate or mixtures thereof, with a second component comprising a source of phosphoric acid or phosphate. The mixture has a molar phosphorous ratio of the first component to the second component of from 1:1 to 1:10. The second step involves either physically or chemically dehydrating the mixture to produce a phosphono-phosphate compound.
揭示了一种制备磷酸酰基磷酸盐化合物的方法。该方法涉及以下步骤:第一步将包含磷酸、膦酸盐或两者混合物的第一组分与含磷酸或磷酸盐的第二组分混合,混合物的磷元素摩尔比为第一组分与第二组分的比为1:1至1:10。第二步涉及将混合物进行物理或化学脱水以产生磷酸酰基磷酸盐化合物。
