Prediction of Hydrogen-Bonding Interaction Free Energies with Two New Molecular Descriptors

open access: yesLiquids
This work is a continuation of our recent work on the prediction of hydrogen-bonding (HB) interaction enthalpies. In the present work, a simple method is proposed for the prediction of the HB interaction free energies.

Extracion of citric acid in 2-octanol and 2-propanol solutions containing tomac: an equilibria and a LSER model [PDF]

open access: yesBrazilian Journal of Chemical Engineering, 2008
Studies on the extraction of citric acid by TOMAC (trioctyl methyl ammonium chloride) dissolved in 2-propanol and 2-octanol (active solvents) and their mixture (1 : 1 volume ratio) are reported. Experimental results of batch extraction experiments are calculated and reported for partitioning coefficients (D), loading factors (Z), and extraction ...
