The experimentally measured densities of ionic liquids are important, since they can be used to develop equations of state, which describe non-ideal behavior of ionic liquids. The density and from it derived volumetric parameters of ionic liquids are required for developing new industrial processes [1]. Density is decreasing with increasing temperature due to increasing kinetic energy, which in turn increases the volume of ions. After linear fitting the parameters a and b for the temperature dependence of density are determined from
$$ \rho =b- aT $$
