摘要：
The ionization constants of five water insoluble anti-inflammatory arylpropionicacids were evaluated in 80% VN N,N-dimethylformamide aqueous mixture. From these values, data on proton dissociation constants in water have been computed and compared with the results previously reported by using different approaches. (C) 1997 Elsevier Science B.V.
