Study of ion-pair and triple-ion origination of an ionic liquid ([bmmim][BF₄]) predominant in solvent systems

Abstract

Electrolytic conductivities, densities, viscosities, and FT-IR spectra of 1-butyl-2,3 dimethylimidazolium tetrafluoroborate ([bmmim][BF4]) have been studied in tetrahydrofuran, dimethylacetamide and methyl cellosolve at different temperatures.

Investigation of an inclusion complex formed by ionic liquid and β-cyclodextrin through hydrophilic and hydrophobic interactions

“…They are also used as heat transfer fluids for processing biomass and as electrically conductive liquids in electrochemistry (batteries and solar cells). [8][9][10] In view of the above and in continuation of our study, [11][12][13][14] we have attempt to ascertain the nature of formation of inclusion complexes of IL insight into the β-cyclodextrin in w1=0.001, 0.003, 0.005 mass fraction of aq. β-cyclodextrin media as a literature survey reveals that no work has been carried out in the present ternary systems.…”

Physicochemical characterizations of novel dicyanamide-based ionic liquids applied as electrolytes for supercapacitors

“…On the other hand, calculated U POT values of our DCA based ILs are lower than values of their corresponding pyrrolidinium, morpholinium and piperidinium analogues. 29,44,45 Such a result suggests a weaker coulombic interactions inside the structure. As the coulombic interactions between the cation and the anion tend to decrease the mobility of the IL, the ionic conductivities of the selected DCA based ILs are expected to be higher than their pyrrolidinium, morpholinium and piperidinium counterparts.…”

“…50 Therefore, the ion-pairs attract the free ions present in the solution and results in the formation of symmetrical triple-ions (eqn (9) and (10)). 44,51 Taking into account the partial formation of ions-pairs, we can consider as a rst approximation that the solution is composed by (i) completely dissociated C + and A À single ions, (ii) completely dissociated C 2 A + and CA 2 À triple ions and (iii) an undissociated part, i.e. the CA ion pairs.…”

Diverse Interactions of N-Methyl Glycine in Aqueous Paracetamol Solution with the Manifestation of Solvation Consequences

“…The value W and V will remain same for the same class of solutes in aqueous solutions and only the volume due to electrostriction will vary. The hydrophilic-hydrophilic, ion-ion and ionhydrophilic interactions will increase with increasing molality of N-methyl glycine and as a result S value will decrease [33]. For this reason, V 0 values increase with increasing molality of N-methyl glycine.…”
