![عکس صفحه اول مقاله: Generalized equation of state for the cyclic hydrocarbons over a temperature range from the triple point to 700 K with pressures up to 100 MPa Generalized equation of state for the cyclic hydrocarbons over a temperature range from the triple point to 700 K with pressures up to 100 MPa](/preview/png/201144.png)
Based on the extended three-parameter corresponding states principle and the most reliable experimental data of cyclic hydrocarbons, a generalized fundamental equation of state for technical calculations has been developed. This equation is in the form of the reduced Helmholtz free energy and takes the reduced density, reduced temperature, and acentric factor as variables. The proposed equation satisfies the critical conditions and Maxwell rule, shows correct behavior for the ideal curves and for the derivatives of the thermodynamic potentials, and allows the calculation of all thermodynamic properties excluding critical region of cyclic hydrocarbons over a temperature range from the triple point to 700 K with pressures up to 100 MPa in the range of variation of the acentric factor ω = 0.2–1.1.
