Abstract

In the present work, a novel phosphonium-based dicationic ionic liquids (DCILs) were synthesised and characterised using 1H NMR and elemental analysis. Physiochemical properties such as density and viscosity are measured and reported for a temperature range of (293.15 to 353.15) K while the refractive index was measured in the range (293.15 to 333.15) K. The start and decomposition temperatures are determined at heating rate 10 °Cmin-1. The influence of the spacer alkyl chain on these properties is discussed. The results show that the new DCILs possess lower density higher thermal stability and higher viscosity compare to monocationic ionic liquids
