Thermophysics of metal alkanoates II. Heat capacities and thermodynamic properties of sodium propanoate

The heat capacity of sodium propanoate has been measured from 9 to 580 K by adiabatic calorimetry and considerable metastability noted between 60 and 215 K. Values at 298.15 K of Cp,m/R, Smo/R, "Hmo-Hmo(0)'/R, and "Gmo-Hmo(0)'/RT are 16.16, 18.29, 2809.1 K, and -8.872. Comparisons with d.s.c. results and other reported phase behavior are provided.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/25432/1/0000882.pd
