Abstract
A new method for estimating high pressure liquid heat capacities based on
molecular structure and group contribution is proposed. A common set of
structural groups was employed. The method was developed using 67 sets of 43
organic compounds with 3449 experimental heat capacity data. A small number
of measured compounds, data points per compound and other comparable methods
were observed. This is a simple first-order approximation with acceptable
accuracy of 2.548%.
