Solubility Prediction of Paracetamol in Binary and Ternary Solvent Mixtures Using Jouyban-Acree Model

Chemical and Pharmaceutical Bulletin, 2006
The Jouyban-Acree model has been used to predict the solubility of paracetamol in water-ethanol-propylene glycol binary and ternary mixtures based on model constants computed using a minimum number of solubility data of the solute in water-ethanol, water-propylene glycol and ethanol-propylene glycol binary mixtures.

Significant Increase in the Solubility of Celecoxib in Presence of Some Deep Eutectic Solvents as Novel Sustainable Solvents and the Thermodynamic Analysis of These Systems [PDF]

Pharmaceutical Sciences, 2020
Background: Deep eutectic solvents (DESs) exist a wide variety of potential and existing applications. Based on the fact that the choline chloride (ChCl) is a complex B vitamin and widely used as food additive, the choline-based DESs are generically ...

Excess Molar Volumes and Viscosities for the Binary Mixtures of n‐Octane, n‐Decane, n‐Dodecane, and n‐Tetradecane with Octan‐2‐ol at 298.15 K

Journal of Thermodynamics, Volume 2013, Issue 1, 2013., 2013
Experimental values of densities (ρ) and viscosities (η) in the binary mixtures of n‐octane, n‐decane, n‐dodecane, and n‐tetradecane with octan‐2‐ol are presented over the whole range of mixture composition at T = 298.15 K. From these data, excess molar volume (VmE), deviations in viscosity (Δη), and excess Gibbs free energy of activation ΔG∗E have ...

Modelling the effects of ethanol on the solubility of the proteinogenic amino acids with the NRTL, Gude and Jouyban-Acree models

Fluid Phase Equilibria, 2018
Abstract The addition of organic solvents, such as ethanol, to molecules in solution is an effective process for crystallization and is used in industrial settings (i.e. pharmaceutical production, downstream processing, etc.). In this study, we use solubility data of all proteinogenic α-amino acids in binary ethanol/water systems to model their ...

Thermodynamic properties of binary mixtures of terpenes and 1-propanol in the temperature range from 288.15 to 323.15 K at atmospheric pressure [PDF]

Hemijska Industrija
Terpenes are the most abundant class of chemical compounds present in essential oils. They are considered green solvents, and come from natural sources such as plants, citrus fruits, but also from tree leaves or pinecones.

The Jouyban-Acree model’s usefulness for estimating ibuprofen and naproxen solubility in some cosolvent mixtures

Ingeniería e Investigación, 2008
Estimating drug solubility in cosolvent mixtures has been an important pharmaceutical science research field at theoretical and practical levels for several decades. The validity of an adapted version of the Jouyban-Acree (J-A) model for predicting ibuprofen (IBP) and naproxen (NAP) solubility in propylene glycol + water cosolvent mixtures was thus ...
