Isochoric heat capacities of ethanol-water mixtures at temperatures from 280 to 420 K and pressures to 30 MPa.

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

Summary

Isochoric heat capacities of ethanol-water mixtures were measured with a twin-cell type adiabatic calorimeter. Temperatures were measured with a platinum resistance thermometer on the bottom of each cell and were reported on the ITS-90. Sample pressure measurements were made with a quartz crystal transducer. Densities were calculated from the volume of the calorimeter cell and sample mass. The experimental expanded uncertainty (with a coverage factor k= 2) of temperature measurements is plus or minus 13 mK, and that of pressure measurement is plus or minus 8 kPa. The expanded relative uncertainty for isochoric heat capacity is estimated to be plus or minus 2% for liquid phase measurements, and for density it is plus or minus 0.16%.
