摘 要: 利用两相滴定法在(25±0 5)℃下测定了仲壬基苯氧基乙酸(CA-100)在水中的溶解度S,离解常数Ka,以及庚烷中的二聚常数K2和水-庚烷两相间的分配常数Kd.实验测得S=1 30×10-4mol/L,Ka=2 94×10-4,K2=3 29×102,Kd=4 15×102. Some basic constants of extractant CA-100 such as solubility(S) in water, dissociation constant(Ka) in aqueous solution, dimerization constant(K2) and distribution constant(Kd) between water-haptane have been determined by two phase titration method. The results are as follows: S=130×10-4mol/L, Ka=294×10-4, K2=329×102, Kd=415×102(25±05)℃.
