用电位法和电导法测定了一系列取代苯酚及其四丁基铵盐在四氢呋喃中的离解常数。在此溶剂中的酸强度的分辨率进行了比较，在其他两亲性和非质子溶剂中获得的。酚类和苯甲酸类在四氢呋喃中的酸强度分离度高于在水中的分离度，也优于在其他溶剂中的分离度。(C)2000 Elsevier Science B.V.保留所有权利。
Dissociation constants of a series of substituted phenols and their tetrabutylammonium salts were determined in tetrahydrofuran by potentiometric and conductometric methods. The resolution of acid strength in this solvent was compared with those obtained in other amphiprotic and aprotic solvents. The resolution of acid strength of phenols and benzoic acids in tetrahydrofuran was higher than in water, and better than that in any of the other solvents considered. (C) 2000 Elsevier Science B.V.
