Investigation of the new room temperature ionic liquid of AL (NO3)‎ 3.9 H2O with urea CO (NH2)‎ 2

Abstract EN

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]ˉ 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 .
