Emerged as pos­si­ble alter­na­tives to volatile organ­ic sol­vents, ion­ic liq­uids have numer­ous appli­ca­tions in a num­ber of research areas. With their unique prop­er­ties and char­ac­ter­is­tics, ion­ic liq­uids are known as green and envi­ron­ment friend­ly sol­vents. High ther­mal and elec­tro­chem­i­cal sta­bil­i­ty, neg­li­gi­ble vapor pres­sure, high sol­vat­ing pow­er, are only few of the ben­e­fits of ion­ic liq­uids. With appli­ca­tions in numer­ous fields, ion­ic liq­uids are most pop­u­lar­ly used in :

Elec­tro­chem­i­cal Devices

The use of ion­ic liq­uids in elec­tro­chem­i­cal devices has proved to be pos­i­tive with out­stand­ing results. When ion­ic liq­uids were used with devices such as lithi­um ion bat­ter­ies, super capac­i­tors, dye-sen­si­­tized solar cells and poly­mer-elec­trolyte fuel cells, pos­i­tive results were wit­nessed. Act­ing as an elec­trolyte in all elec­tro­chem­i­cal devices, ion­ic liq­uids should be resis­tant to elec­tro­chem­i­cal oxi­da­tion and radi­a­tion. The two major ben­e­fits why these are uti­lized with elec­tro­chem­i­cal devices are the non-volatil­i­­ty and pre­ven­tion of elec­trolytes from dry­ing dur­ing the oper­a­tion. Offer­ing a wide elec­tro­chem­i­cal win­dow is the main require­ment of an ion­ic liq­uid to be used in devel­op­ing elec­tro­chem­i­cal appli­ca­tions. Addi­tion­al­ly, the high vis­cous liq­uid, when mixed with propy­lene car­bon­ate, results in a decrease in vis­cos­i­ty, pro­vid­ing bet­ter out­put data as com­pared to tra­di­tion­al sys­tems.

Chem­i­cal Processes

Ion­ic liq­uids serve as promis­ing sol­vents in var­i­ous organ­ic reac­tions such as Bails-Hill­­man, ester­i­fi­ca­tion, Diels-Alder, Heck Reac­tion, iso­mer­iza­tion reac­tions and many more. The progress of the reac­tion is deter­mined by con­cen­tra­tions, pres­sure and tem­per­a­ture of the reac­tants. Fur­ther­more, it has also been observed that, vis­cos­i­ty plays an essen­tial role in reac­tion kinet­ics. Accord­ing to the results, in addi­tion to vis­cos­i­ty, the rates are influ­enced by a sol­vent prop­er­ty – its vari­a­tion, inde­pen­dence of vis­cos­i­ty and chang­ing of one series of anions to anoth­er.

Extrac­tion Technology

Sol­vent extrac­tion is uti­lized in nuclear pro­cess­ing, pro­duc­tion of organ­ic com­pounds, ore pro­cess­ing, pro­cess­ing per­fumes and oth­er dif­fer­ent indus­tries. Ion­ic liq­uids are used to sep­a­rate tox­ic met­al ions and organ­ic mol­e­cules. Cur­rent­ly, ion­ic liq­uids are used to sep­a­rate met­al ions with the use of crown ethers. Crown ethers help in extract­ing met­al ions from aque­ous solu­tions. The effi­cien­cy of this process depends on the counter anions as well as cations. To remove stron­tium nitrate from aque­ous phase, ion­ic liq­uids are used ; since crown ethers are inef­fi­cient in this process. With numer­ous appli­ca­tions, ion­ic liq­uids are becom­ing one of the most used sol­vents in the chem­i­cal indus­try.
