Abstract:A unified two-parameter approximation formula is used to derive analytical dependences for P(T) curves of liquid–vapor phase equilibrium of saturated hydrocarbons C_nH_2n + 2 (alkanes) with numbers 1 ≤ n ≤ 20 from methane (n = 1) to eicosane (n = 20). Two approximation options are given, namely, that involving the use of individual values of parameters for each alkane, and that in the form of a unified formula in which the only parameter characterizing an individual component is the number n.
