Abstract New densities are reported over the whole composition range for 1-iodoperfluorohexane+n-octane system at temperatures from 288.15 to 308.15K at atmospheric pressure. These data have been used to compute the excessmolar volumes, VmE.Large positive VmEvalues have been obtained over the entire range of composition, which increaseswhen the temperature rises. The experimental data were used to calculate theisobaric thermal expansivity, and the quantities (∂VmE/∂T)p and (∂HmE/∂p)T. Furthermore,the results have been used to investigate the volumetric prediction abilityof the equations of state Soave–Redlich–Kwong, Peng–Robinson,Patel–Teja and Soave–Redlich–Kwong with volume translation.
