Abstract:

The critical temperatures, pressures, heat capacities, and thermal diffusivities of saturated triglycerides C3H5{[}CnF2n-1O2](3) with n = 8, 10, 12, 14 have been measured. The experimental critical constants of triglycerides have been compared with those calculated using the group contribution methods of Constantinou and Gani, Marrero and Gani, Hukkerikar and co-workers, and Cunico and co-workers. The heat capacities and thermal diffusivities have been measured in the temperature range from about the melting point of a triglyceride to 410-425 K. The temperature dependencies of the heat capacities and thermal diffusivities have been approximated by a third-order and a first-order polynomial, respectively. The coefficients of these polynomials have been given. Using the experimental data, the thermal conductivities of triglycerides have been calculated. (C) 2017 Elsevier Ltd.
