摘要
The critical temperature of heavy n-alkanes is predicted from the behaviour corresponding to their melting temperature and from several empirical correlations. The prediction methods for the critical temperature of n-alkanes are reviewed, including the new experimental data currently available. The results obtained for T-c(infinity) the limiting value of the critical temperature at n --> infinity, are compared. The calculated and experimental values of T-c coincide in the range n = 5-36 within the actual uncertainties.
