Saturated-liquid heat capacity of organic compounds: New empirical correlation model

Abstract

A new saturated-liquid heat capacity model is recommended. This model is tested and compared with the known polynomial and quasi-polynomial models on 39 sets with 1453 experimental heat capacity data. The obtained results indicate that the new model is better then the existing models, especially near the critical point.

U ovom radu je preporučen nov empirijski model za korelisanje toplotnog kapaciteta zasićene tečnosti organskih jedinjenja. Model je testiran i upoređen sa poznatim polinomskim i kvazi-polinomskim modelima korišćenjem 39 setova sa 1453 eksperimentlna podatka. Dobijeni rezultati ukazuju da je nov model bolji od postojećih, naročito u okolini kritične tačke.
