Abstract

âº VmE of the title systems was calculated via densities from the vibrating tube method. âº VmE of benzeneÂ +Â cyclohexane agrees well with old data from pycnometric measurement. âº Experimental results were correlated by Redlich-Kister and Peng-Robinson expressions. âº The harmonic rule (instead of geometric) was used to get Peng-Robinson constant a12.
