DEEA、DBEA、DHEA共轭酸的解离常数pKa值的测定

DETERMINATION OF THE IONIZATION CONSTANT OF CONJUGATE ACIDS FOR DEEA, DBEA AND DHEA

通过 ｐＨ电位滴定法测定了在 ２５ ℃，离子强度为 ０． １０ ｍｏｌ／Ｌ，以 ＫＮＯ３为支持电解质条件下 Ｎ，Ｎ－二乙基邻乙基苯胺（ＤＥＥＡ）、Ｎ，Ｎ－二丁基邻乙基苯胺（ＤＢＥＡ）、Ｎ，Ｎ－二己基邻乙基苯胺（ＤＨＥＡ）共轭酸的解离常数。

Under the ionic strength of 0. 1 mol/L at 25 ℃ and in the presense of KNO3 as supporting electrolyte, the pKa of conjugate acids for DEEA, DBEA and DHEA were determined with pH potential titration.
