This paper presents the comparative study of correlations as to estimate the densities of ionic liquids. The correlations used in this study are of generalized correlation and the one that is developed for the calculation of the density of saturated and normal liquid. 8 correlations are used in this study and the accuracy of the correlations is determined by calculating the deviations. The generalized models used in the estimation of ionic liquids density are Yamada and Gunn – YG (1973, pg. 234), Reid et al. – RR (1977), Bhirud – BH (1978, pg. 1127), Hankinson and Thomson – HT (1979, pg. 653), Valderrama and Abu Sharkh – VSY and VSD (1989, pg. 87), Mchaweh et al. – MH (2004, pg. 157) and Valderrama and Zarricueta – VZ (2009, pg. 145). In this paper, 139 density data of imidazolium based ionic liquids, 57 of ammonium based and 20 density data of pyridinium based ionic liquids are assembled to conduct the study. The best correlation to be used for the estimation of ionic liquids density is determined based on the lowest deviations calculated.
