Isobaric Molar Heat Capacity of Ethyl Octanoate and Ethyl Decanoate at Pressures up to 24 MPa

Abstract

The isobaric molar heat capacities of ethyl octanoate and ethyl decanoate were determined at T = 294–354 K and p = 0.1–24 MPa. The measurements were conducted by a flow calorimeter. The measured results were in good agreements with several available experimental data at atmosphere pressure and the calculated results at high pressure in literatures. Furthermore, a fitting equation was presented to calculate the Cp of ethyl octanoate and ethyl decanoate. The maximum absolute relative deviations between experimental results and calculated data are lower than 0.4%.
