摘要
用 p H滴定法测定了标题化合物在 2 5± 0 .1℃、3 5± 0 .1℃和 4 5± 0 .1℃ KNO3 存在下的离解常数 ;计算了 2 5± 0 .1℃离解反应的焓变Δr Hm和熵变Δr Sm。确定了 2 5± 0 .1℃ KNO3 存在下 ,它与 Co( )、Ni( )及Cu( )
The dissociation constants of N benzyl glycine N ethylphosphonic acid have been measured by pH titration method at temperatures 25±0.1℃,35±0.1℃ and 45±0.1℃ respectively. Δ rH m and Δ rS m of the reaction have also been calculated.The stability constants of it's Co(Ⅱ),Ni(Ⅱ) and Cu(Ⅱ) complexes have been meacured by the same method under conditions of I=0.1 mol·dm -3 and in the presence of KNO 3.
