ABSTRACT

Heat capacities and densities are significant in the design or the improvement of processes such as the blending of biofuels. An automated flow calorimeter, developed in our group, was used for the accurate measurement of isobaric heat capacities for pure compounds and mixtures over the range (250 to 400) K and (0 to 20) MPa. In this paper, isobaric heat capacities for cyclohexane and 1-hexene and their binary mixtures with ethanol are reported. Also the densities have been measured using an automated densimeter up to 70 MPa.
