Abstract The isobaric heat capacity of 1,3-diethylbenzene was studied in the liquid phase. A total of 68 experimental data were acquired for ten isotherms from 303.16 K to 489.81 K in the pressure range of 0.17 MPa to 12 MPa. The experimental data were correlated with an empirical equation. The isobaric heat capacity of water was measured to verify the reliability of the experimental system before this experiment.
