IONIC LIQUIDSAN 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.

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”.

SYNTHESIS IONIC LIQUIDS ARE

MANUFACTURED FROM VOC’S.

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.

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.

GREEN CHARACTER OF IONIC LIQUIDS

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”.
