Specific Heats of Saturated and Compressed Liquid Propane

Experimental specific heats for saturated liquid propane, along the coexistence path, have been determined from the triple-point temperature (~ 85 K) to 289 K. Specific heats for the compressed liquid at constant molal volume have been determined along isochores at nine different densities ranging from near the triple-point liquid density to about twice the critical-point density (at pressures up to 300 bar). Comparisons with previous experimental- and/or derived-data show agreement within combined uncertainties of about three percent.
