Isochoric specific heat capacity measurements for liquid isobutane.

Author(s) : MIYAMOTO H., KITAJIMA H., KAGAWA N., et al.

Summary

Experimental isochoric specific heat capacities (Cv) and properties for isobutane are presented that were measured with a twin-cell type adiabatic isochoric calorimeter. The measurements were obtained for temperatures from 272 to 408 K and for pressures up to 30 MPa. The sample purity was 99.99 mol%. The expanded uncertainties (i.e. a coverage factor k= 2) are 13 mK for temperature, 8 kPa for pressure, 0.16% for density and 3.6% for Cv in the liquid phase. An evaluation and a comparison of the experimental data with highly reliable equations of state confirmed satisfactorily the thermodynamic consistency of the measurements.
