摘要：

Dissociation constants of a series of substituted benzoic acids and their tetrabutylammonium salts were determined in tetrahydrofuran by Potentiometric and conductimetric methods. A comparison of the pK(a) values of the acids with those obtained in other amphiprotic and aprotic media showed the better resolution of acid strength in tetrahydrofuran.
