Journal ArticleDOI
Ionic-Liquid-Mediated Extraction and Separation Processes for Bioactive Compounds: Past, Present, and Future Trends
Sónia P. M. Ventura,Francisca A. e Silva,Maria V. Quental,Dibyendu Mondal,Mara G. Freire,João A. P. Coutinho +5 more
TL;DR: The key accomplishments and future challenges to the field are discussed, with particular emphasis on the major lacunas found within the IL community dedicated to separation processes and by suggesting some steps to overcome the current limitations.
Journal ArticleDOI
Evaluation of Anion Influence on the Formation and Extraction Capacity of Ionic-Liquid-Based Aqueous Biphasic Systems
Sónia P. M. Ventura,Catarina M. S. S. Neves,Mara G. Freire,Isabel M. Marrucho,João Pedro Oliveira,João A. P. Coutinho +5 more
TL;DR: It is shown that the partition coefficients obtained between the IL and the K(3)PO(4)-aqueous rich phases were substantially larger than those typically obtained withpolymers-inorganic salts or polymers-polysaccharides aqueous systems.
Journal ArticleDOI
Toxicity assessment of various ionic liquid families towards Vibrio fischeri marine bacteria.
Sónia P. M. Ventura,Carolina S. Marques,Andreia A. Rosatella,Carlos A. M. Afonso,Fernando Gonçalves,João A. P. Coutinho +5 more
TL;DR: These new results clearly show that guanidinium-, unlike the imidazolium- and phosphonium-based ILs, do not follow the trend of increasing toxicity with the increase in the alkyl chain length, and the introduction of oxygenated groups on theAlkyl chains leads to a decrease of the toxicity of guanIDinium and also imidrazolium compounds.
Journal ArticleDOI
Designing ionic liquids: the chemical structure role in the toxicity
Sónia P. M. Ventura,Ana M. M. Gonçalves,Ana M. M. Gonçalves,Tânia E. Sintra,Joana Luísa Pereira,Fernando Gonçalves,João A. P. Coutinho +6 more
TL;DR: The results here reported suggest the possibility of designing ILs with an enhanced hydrophobic character and lower toxicity, by elimination of their aromatic nature.
Journal ArticleDOI
Ecotoxicity analysis of cholinium-based ionic liquids to Vibrio fischeri marine bacteria
Sónia P. M. Ventura,Francisca A. e Silva,Ana M. M. Gonçalves,Joana Luísa Pereira,Fernando Gonçalves,João A. P. Coutinho +5 more
TL;DR: The results suggest that the cholinium family exhibits a different mechanism of toxicity as compared to the imidazolium ionic liquids previously described in the literature.
