Twu, C.H., 1983. Prediction of thermodynamic properties of normal paraffins using only normal boiling point. Fluid Phase Equilibria, 11: 65–81. The main objective of this work is to develop a generalized equation of state for normal alkanes from only the normal boiling point. Since the equation of state for normal alkanes is found to be a function only of normal boiling-point temperature, the new correlation should be very useful for correlating departures of other systems from normal-alkane behavior using a normal alkane as a nonspherical reference. The equation of state represents accurately the vapor pressures, densities and enthalpy departures of the vapor, liquid and fluid states as a function only of boiling-point temperature over the entire range of interest for the normal paraffins methane (CH 4) through n-hectane (C 100H 202).
