In this work, the isobaric molar heat capacities of ethyl caprylate and ethyl caprate were measured within the temperatures from 294 K to 354 K and at pressures from 0.1 MPa to 24.1 MPa. The measurements were carried out using 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 literature. The molar heat capacities of ethyl caprylate and ethyl caprate were observed to increase with increasing temperature and decrease with increasing pressure. In addition, a correlation was proposed to predict the isobaric molar heat capacities of ethyl caprylate and ethyl caprate. The maximum absolute relative deviations between predicted and experimental isobaric molar heat capacities are lower than 0.4%.
