Quantifying intermolecular interactions of ionic liquids using cohesive energy densities

For ionic liquids (ILs), both the large number of possible cation + anion combinations and their ionic nature provide a unique challenge for understanding intermolecular interactions. Cohesive energy density, ced, is used to quantify the strength of intermolecular interactions for molecular liquids, and is determined using the enthalpy of vaporization. A critical analysis of the experimental ch...

An Improvement to the Properties of GAP Binder with Energetic Ionic Liquids

Glycidyl azide polymer (GAP) is used as a binder in the propellants. Energetic ionic liquids are used as a plasticizer to correct the properties of polymer. In this study, first ionic liquid was bonded to the GAP by certain amount and then the energetic anions of nitrate (NO3) and azide (N3) were used to exchange anion. FTIR analyses confirm accurately anions exchange. DSC, viscometer and heat ...

An Accurate Empirical Correlation to Estimate Sonic speed of Ionic Liquids

In recent years there has been a great deal of attention paid by researchers in investigating ionic liquids (ILs) mainly due to the tremendous potential that ionic liquids have in reaction and separation technology. Sonic speed is an important thermodynamic property of ionic liquids (ILs) and always chosen as a source to determine other properties. A database for the sonic speed of pure ILs cre...

Micelle formation of a non-ionic surfactant in non-aqueous molecular solvents and protic ionic liquids (PILs).

Many ionic liquids and low molecular weight polar solvents have been reported to support amphiphile self-assembly, with most of these reported for the first time in the last decade. This phenomenon is attributed to the solvophobic effect (analogous to the hydrophobic effect in water). However, to date there has been no systematic study which evaluates micelle formation in a large library of non...

Voltammetric Determination of Tryptophan Using a Carbon Paste Electrode Modified with Magnesium Core Shell Nanocomposite and Ionic Liquids

A novel carbon paste electrode modified with ionic liquid (n-hexyl-3-methylimidazolium hexafluoro phosphate) and magnetic core-shell manganese ferrite nanoparticles (MCSILCPE) was fabricated. The electrochemical study of the modified electrode, as well as its efficiency for electro-oxidation of tryptophan, is described. Cyclic voltammetry (CV), choronoamperometry (CHA) and square wave voltammet...
