摘要: <正>在室温及恒定的离子强度条件下,用pH电位法首次测定了单宁酸和木麻黄单宁的加质子常数,并分别求出各单宁配体的分布系数。还测定了它们的若干金属配合物的稳定常数。用同样方法还对苯酚、邻苯二酚及没食子酸三个模型化合物的加质子常数和有关金属配合物的稳定常数进行了测定。

Abstract: The protonation constants of tannins and its coordination compounds stability constants were studied by equilibrium pH method at 20癈 and constant ionic strength. The result shows the distribution diagram of ligands of tannins respectively. In the same way, the protonation constants and stability constants of three kinds of models about phenol, catechol and pyrogallol were determined.
