1. Active component (1-hydroxyethylidene-1 1-diphosphonic acid) content. 1.1 Oxidative decomposition method The active component of the finished product, 1-hydroxyethylidene-1 1-diphosphonic acid, and impurity phosphorous acid. Under appropriate oxidative decomposition conditions, both are converted to n-phosphonic acid. Then measure the data in a corresponding method. The total amount of n-phosphonate represents the amount of phosphinate which […]
