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。
Under room temperature and constant ionic strength, the proton constants of tannin and casuarine were determined by pH potential method for the first time, and the distribution coefficients of each tannin ligand were calculated. The stability constants of several of their metal complexes were also determined. The same method was also used to determine the proton constants and the stability constants of the metal complexes of the three model compounds of phenol, catechol and gallic acid.
