摘要
The aqueous solubility (S-w) of liquids and solids, expressed as log S-w as well as their partition coefficients in different solvent systems viz. P-oct (partition coefficient in octanol-water), P-16 (partition coefficient in water-hexadecane), P-alk (partition coefficient in water-alkane), and P-cyc (partition coefficient in water-cyclohexane), and aqueous solubility (S-w) have been estimated using the PI (Padmakar-lvan) index and the results compared with those obtained using the widely used Wiener index (W). Regression analysis of the data using n-alkanes show that the PI index gives better results than the W index. (C) 2002 Elsevier Science Ltd. All rights reserved.
