Abstract
Mixing aluminum nitrate nonahydrate with urea produced room temperatures clear colorless ionic liquid with lowest freezing temperature at (1: 1.2) mole ratio respectively. Freezing point phase diagram was determined and density, viscosity and conductivity were measured at room temperature. It showed physical properties similar to other ionic liquids. FT-IR,UV-Vis, 1H NMR and 13C NMR were used to study the interaction between its species where - CO ??? Al- bond was suggested and basic ion [Al(NO3)4]? and acidic ions [Al(NO3)2. xU]+ were proposed. Water molecule believed to interact with both ions. Redox potential was determined to be about 2 Volt from – 0.6 to + 1.4 Volt with thermal stability up to 326 ?.
Highlights
Ionic liquids can be defined as a new class of solvents, or as salts with the melting point arbitrarily determined to be below 100°C
This liquid was found to have a conductivity of 9.09mS cm-1, density 1.6028 g .cm-3 and viscosity of 20.579 pois at 25, Table (1) shows a comparison at between three ionic liquids (ILs) on urea with three different aluminum salts 25
The effects of temperatures on the density and viscosity of the new ionic liquid (IL) in this work has both density and the viscosity to be decreased with increasing temperature
Summary
Ionic liquids can be defined as a new class of solvents, or as salts with the melting point arbitrarily determined to be below 100°C. They are composed of ions and, each IL possesses unique properties that are due to cation and an anion nature[1,2,3,4]. A type of ionic liquids is the eutectic solvents, which have interesting solvent properties. A series of ternary deep eutectic solvents made from sugarurea- salt mixtures were reported as solvents for organic synthesis[10]. One of other reported ionic liquids by Abood and co workers, involves the addition of a simple amide to AlCl3 resulting in the
