摘要：

The chemical equilibria involved in titrations of diprotic bases in anhydrous acetic acid were studied. Five independent dissociation constants, plus the autoprotolysis constant, are needed to describe and solve the ionic equilibria present in the basic part of the titration. Methods to determine these dissociation constants are proposed and tested. The dissociation constants of lysine and arginine were determined.
