Surface hydrophobization of bacterial and vegetable cellulose fibers using ioni...
Tomé, Liliana C.; Freire, Mara G.; Rebelo, Luís Paulo N.; Silvestre, Armando J. D.; Carlos Pascoal Neto; Marrucho, Isabel M.; Freire, Carmen S. R.The surface hydrophobization through heterogeneous chemical modification of bacterial (and vegetable) cellulose fibers with several anhydrides (acetic, butyric, hexanoic and alkenyl succinic anhydrides) and hexanoyl chloride suspended in an ionic liquid, tetradecyltrihexylphosphonium bis(trifluoromethylsulfonyl) imide, [TDTHP][NTf(2)], was studied. Furthermore, in the reaction with hexanoyl chloride, another io...
Densities and Derived Thermodynamic Properties of Imidazolium-, Pyridinium-, Py...
Gardas, Ramesh L.; Costa, Henrique F.; Freire, Mara G.; Carvalho, Pedro J.; Marrucho, Isabel M.; Fonseca, Isabel M. A.; Ferreira, Abel G. M.In the present work, experimental density measurements are reported along with the derived thermodynamic properties, such as the isothermal compressibility (κT), the isobaric expansivity (αp), and the thermal pressure coefficient (γv) for imidazolium-, pyridinium-, pyrrolidinium-, and piperidinium-based ionic liquids (ILs), namely, 1-ethyl-3-methylimidazolium trifluoromethanesulfonate [C2mim][CF3SO3], 3-methyl-...

Tomé, Luciana I. N.; Carvalho, Pedro J.; Freire, Mara G.; Marrucho, Isabel M.; Fonseca, Isabel M. A.; Ferreira, Abel G. M.; Coutinho, João A. P.In the present work, experimental density measurements are reported along with the derived thermodynamic properties, such as the isothermal compressibility (κT), the isobaric expansivity (αp), and the thermal pressure coefficient (γv) for imidazolium-based ionic liquids (ILs), namely, 1-ethyl-3-methylimidazolium methylsulfate [C2mim][MeSO4], 1-ethyl-3-methylimidazolium ethylsulfate [C2mim][EtSO4], 1,3-diethylim...
High pressure solubility data of carbon dioxide in (tri-iso-butyl(methyl)phosph...
Ventura, Sónia P. M.; Pauly, Jérôme; Daridon, Jean L.; Silva, J. A. Lopes da; Marrucho, Isabel M.; Dias, A. M. A.; Coutinho, J. A. P.Ionic liquids are attracting great attention nowadays due to their interesting properties which make them useful in a broad range of applications including reaction media or separation/capture of environmentally hazardous gases such as carbon dioxide. In many cases, for practical and/or economical reasons, the use of aqueous solutions of ILs would be preferable to their use as pure compounds. In this work, high...
High-Pressure Densities and Derived Thermodynamic Properties of Imidazolium-Bas...
Gardas, Ramesh L.; Freire, Mara G.; Carvalho, Pedro J.; Marrucho, Isabel M.; Fonseca, Isabel M. A.; Ferreira, Abel G. M.; Coutinho, João A. P.This work addresses the experimental measurements of the pressure (0.10 < p/MPa < 10.0) and temperature (293.15 < T/K < 393.15) dependence of the density and derived thermodynamic properties, such as the isothermal compressibility, the isobaric expansivity, the thermal pressure coefficient, and the pressure dependence of the heat capacity of several imidazolium-based ionic liquids (ILs), namely, 1-butyl-3-methy...
