Abstract
According to the definition of liquid constant pressure heat capacity and the Rackett equation, a new correlation model for liquid constant pressure heat capacities of organic compound was proposed in this paper. From the proposed model, heat capacities of 46 kinds of liquid organic compounds with 318 data points at different temperatures were predicted. The comparison with the literature data shows that the calculation results are satisfactory with the overall average relative deviations of 3.92%, so the proposed correlation is more accurate than literature correlations. The proposed model is applicable to predict the liquid constant pressure heat capacities of every organic compound at different temperatures. The proposed model is simple and convenient. By using the easy ferreted out physical properties of mole mass, critical temperature, critical pressure,normal boiling point, normal melting point, critical compress factor and eccentric factor, the liquid constant pressure heat capacities of the organic compound at different temperatures can be directly predicted without the need of the constant pressure heat capacity data of corresponding ideal gas.关键词
