| Abstract: | To understand the
molecular interactions between
N,N-dimethylformamide with two families of ionic liquids, the thermophysical
properties such as densities and ultrasonic sound speeds have been measured over the entire composition range at 25 oC under atmospheric
pressure. The materials investigated in the present study include two families
of ionic liquids, viz., ammonium salts and imidazolium salts. Diethyl ammonium
acetate, triethyl ammonium acetate, triethyl ammonium dihydrogen phosphate and
triethyl ammonium sulphate are the ammonium salts while 1-benzyl-3-methylimidazolium
chloride belongs to the imidazolium family. The intermolecular interactions and structural effects are analyzed on
the basis of the measured and derived properties. A
qualitative analysis of the
results are discussed in terms of the ion-dipole interactions, ion-pair
interactions and hydrogen bonding between the ionic liquids and N,N-dimethylformamide molecules. |
