Phase behaviour of room temperature ionic liquid solutions: an unusually large co-solvent effect in (water + ethanol)
Vesna Najdanovic-Visak,José M. S. S. Esperança,Luís Paulo N. Rebelo,Manuel Nunes da Ponte,Henrique J. R. Guedes,Kenneth R. Seddon,Jerzy Szydlowski +6 more
TL;DR: For a molar ratio of 1∶1 of water to ethanol, the co-solvent effect in the nearcritical demixing temperature can be as large as 80 K as discussed by the authors.
Journal ArticleDOI
Pressure, Isotope, and Water Co-solvent Effects in Liquid−Liquid Equilibria of (Ionic Liquid + Alcohol) Systems
Vesna Najdanovic-Visak,José M. S. S. Esperança,Luís Paulo N. Rebelo,Manuel Nunes da Ponte,Henrique J. R. Guedes,Kenneth R. Seddon,Hermínio C. de Sousa,Jerzy Szydlowski +7 more
TL;DR: In this article, the authors used a phenomenological approach based on a "polymer-like" G(E) model coupled with the statistical-mechanical theory of isotope effects.
Journal ArticleDOI
Evidence for Lower Critical Solution Behavior in Ionic Liquid Solutions
Joanna Lachwa,Jerzy Szydlowski,Vesna Najdanovic-Visak,Luís Paulo N. Rebelo,Kenneth R. Seddon,Manuel Nunes da Ponte,José M. S. S. Esperança,Henrique J. R. Guedes +7 more
TL;DR: Lower critical solution temperatures (LCST)-type of phase diagrams have been encountered for the first time in binary and quasi-binary liquid solutions of ionic liquids and constitute the first experimental support for the existence of a theoretically postulated, but never encountered, special kind of type VII phase diagram.
Journal ArticleDOI
The Influence of Phase Behavior on Reactions at Supercritical Conditions: The Hydrogenation of α-Pinene
TL;DR: In this paper, results on the hydrogenation of α-pinene, a liquid reactant, in supercritical (SC) CO2 are presented, and visual observation of phase equilibria under the conditions of the reaction experiments was also performed.
Journal ArticleDOI

Ricardo Ferraz,Ricardo Ferraz,Luís C. Branco,Isabel M. Marrucho,João M. M. Araújo,Luís Paulo N. Rebelo,Manuel Nunes da Ponte,Cristina Prudêncio,Cristina Prudêncio,João Paulo Noronha,Željko Petrovski +10 more
TL;DR: In this article, a novel ionic liquids containing ampicillin as an active pharmaceutical ingredient anion were prepared with good yields by using a new efficient synthetic procedure based on the neutralization of a moderately basic ammonia solution of ampicillus with different organic cation hydroxides.
