Green Solvents Flashcards
(5 cards)
1
Q
alternatives to organic solvents
A
no solvents, water, supercritical CO2 and ionic liquids
2
Q
ionic liquids
A
solely ions, best with poor coordinating ions
3
Q
adv of ionic liquids
A
virtually no vapour pressure so not lost to environment, thermally robust, can tune hydrophobicity/philicity to aic separation, highly conducting and can dissolve enzymes
4
Q
disadv of ionic liquids
A
aqueous waste is an environmental concern
5
Q
supercritical fluid
A
dense phase liquids, combination of properties from liquid and gas states, removed by lowering pressure below critical value
