Prediction of Critical Temperature and Pressure of Hydrocarbons Using Simple Molecular Properties

Fitting their critical temperature (Tc) and critical pressure (Pc) as functions of molecular weight and carbon atomic fraction was done using 470 hydrocarbons (CnHm). Tc=a*(Cfrac)b*(MW)c and Pc=a*(Cfrac)1/3+b*(MW)1/3+c are the non-linear regressed parameters for the given model; Cfrac is the carbon atomic fraction in a molecule, which is equal to n/(n+m) for a hydrocarbon compound; and…
