3. IONIC LIQUIDS
AN IONIC LIQUID IS A SALT IN WHICH
THE IONS ARE POORLY
COORDINATED,WHICH RESULTS IN
THESE SOLVENTS BEING LIQUID
BELOW 100 DEGREE CENTIGRADE OR
EVEN AT ROOM TEMPERATURE.AT
LEAST ONE ION HAS A DELOCALIZED
CHARGE & ONE COMPONENT IS
ORGANIC,WHICH PREVENTS THE
FORMATION OF A STABLE CRYSTAL
LATTICE.
4. PROPERTIES OF IONIC
LIQUIDS
• THEY ARE A CLASS OF ORGANIC SALTS THAT ARE
LIQUID AT OR NEAR ROOM TEMPERATURE.
• THEY ARE NON VOLATILE & NON-FLAMMABLE.
• THEY HAVE BEEN PROPOSED AS RECYCLABLE
“GREEN SOLVENTS”.
5. SYNTHESIS
IONIC LIQUIDS ARE
MANUFACTURED FROM VOC’S.
6. RECYCLING
RESEARCHERS ALSO NEED TO FIND
BETTER WAYS TO RECYCLE IONIC
LIQUIDS. MANY PROCESSES FOR
CLEANING UP IONIC LIQUIDS
INVOLVE WASHING WITH WATER OR
VOCS.
7. IONIC LIQUID’S IMPACT ON
AQUATIC ECOSYSTEM
• THE IMPACT IONIC LIQUIDS HAVE ON
AQUATIC ECOSYSTEM IS PARTICULARLY
IMPORTANT, GIVEN THEIR NON-VOLATILE
NATURE AND MILD TO HIGH SOLUBILITY IN
WATER OF SOME OF THEM.
• IN 2004 PROF.JOAN BRENNECKE AT THE
UNIVERSITY OF NOTRE DAM CONDUCTED A
RESEARCH BASED ON A COMMON FRESH
WATER CRUSTACEANS NAMED DAPHNIA
MAGNA.
10. CONCLUSION
• MANY OF THE BASIC PHYSICAL
PROPERTIES OF IONIC LIQUIDS
ARE STILL UNKNOWN.
• IONIC LIQUIDS ARE IMPORTANT
SOLVENTS IN CHEMICAL
INDUSTRY , & ARE OFTEN
LABELED WITH “GREEN
CHEMISTRY”.
