Solution Thermodynamics of Sodium Diclofenac in Ethanol + Water Mixtures and Correlation with the Jouyban-Acree Model [PDF]

, 2012
The solubility of sodium diclofenac (NaDIC) in several ethanol + water mixtures was determined at 293.15 K to 313.15 K. The thermodynamic functions Gibbs energy, enthalpy, and entropy of solution were obtained from these solubility data by using the van’

Correlation of retention factor of analytes in quaternary solvent mobile phases using the Jouyban-Acree model.

Die Pharmazie, 2006
The Jouyban-Acree model has been used for the mathematical representation of retention factors of phenobarbital, phenytoin and carbamazepine in quaternary aqueous-organic solvent mobile phases. The accuracy of the proposed model is evaluated using average percentage deviation (APD) of experimental and calculated values as an accuracy criterion.

Volumetric properties of (peg 400 + water) and (peg 400 + ethanol) mixtures at several temperatures and correlation with the jouyban-acree model [PDF]

, 2012
Molar volumes and excess molar volumes were investigated from density values for (PEG 400 + water) and (PEG 400 + ethanol) binary mixtures at temperatures from 283.15 K to 313.15 K. Both systems exhibit negative excess volumes probably due to increased interactions like hydrogen bonding and/or large differences in molar volumes of components.
