Isobaric Heat Capacity at Bubble Point of Four Hydrocarbons

The isobaric heat capacity of the bubble-point liquid was determined for propene at temperatures from 80° to 160°F, and for neohexane, cyclohexane, and iso-octane in the temperature range from 80° to 200°F. An equation for obtaining the isobaric heat capacity has been derived which employs volumetric correction terms applied to the heat capacity of the substance as measured in an isochoric adiabatic calorimeter. The results are presented in both graphical and tabular form.
