Isobaric molar heat capacities of binary mixtures containing methyl caprate and methyl laurate at pressures up to 16.2 MPa

Abstract In this work, the isobaric molar heat capacities of methyl caprate, methyl laurate and their mixtures at temperatures from 313 K to 335 K and at pressures up to 16.2 MPa were measured using a flow calorimeter. The isobaric molar heat capacities of these mixtures were observed to increase as the temperature and the concentration of methyl laurate rise, while they increase as the pressure falls. The excess molar heat capacities were calculated using the experimental heat capacity data, which are positive and very small compared to the isobaric molar heat capacities. A correlation was proposed for the isobaric molar heat capacities of the methyl caprate and methyl laurate mixtures with the maximum deviation of 1.8%.
