| Abstract: | Expression for calculating vapor heat capacity was derived from the virial equation corrected by using the model of molecular aggregation. The relationship between vapor heat and temperature for 11 kinds of vapor associated lower aliphatic alcohols was correlated. The calculated vapor heat capacities were in good agreement with the observed data from the calorimetric experiment. Furthermore, the association equilibrium constants of these alcohols were obtained and the values were comparable to those in literatures. |
