- 論文の詳細を見る
1-Dialkylaminoalkylidenediphosphonic acids were obtained by the reaction of N, N-dialkylaliphatic acid amides with phosphorus trichloride, and subsequent treatment with acetic acid.<BR>The dissociation constants (pKa) of these aminodiphosphonic acids were determined from the titration curves. The behavior of dimethylaminomethylenediphosphonic acid and 1-dimethylaminoethylidene-diphosphonic acid toward metal ions was investigated, and it was found that these aminodiphosphonic acids could be utilized for chelating agents.
