Abstract

The field and phenomenon of room-temperature ionic liquids are now well past infancy, but much work remains to be done to fulfill the true potential of these neoteric solvents. As the global leader in the production of phosphine and phosphine derivatives. In this study, we report on the synthesis and characterization of three new ILs compounds with triphenyl Phosphonium cations and different anions such as [PCl5X] (X=F,Cl,I) by using straight forward precipitation reactions. During this study we report the optimized geometries and infrared spectral measurements, 31P-NMR spectroscopies,Thermal analysis TGA and DTA, CV, physical properties of viscosity and density the room-temperature ionic liquids, assignments and electronic structure calculations for new ILs. The structures of ILs have been optimized by the density functional theory (DFT) based method at B3LYP/6-311G levels of theory, using the Gaussian 03 package of programs [6- 10].The comparison between theory and experiment is made.
