Entropy and Related Thermodynamic Properties of Propionitrile

The heat capacity and the heats and temperatures of the transitions of propionitrile have been determined experimentally. One solid transition occurred at 176.964±0.005°K and the melting point at 180.37±0.03°K. The entropy of the ideal gas at 25°C and 1 atm is 68.75±0.15 cal/deg mole.
