A non-cubic equation of state is used to predict the solid-liquid, solid-vapor and liquid-vapor coexistences of pure substances. The equation of state is obtained using as input data the critical point, the boiling temperature, the triple point temperature and the acentric factor of the substance. In this work, some examples of phase diagrams predicted with the equation of state are reported in order to show its capabilities. Finally, a database with the parameters for different pure substances is presented.
