Abstract. The coexisting liquid and vapour densities of ethylene are determined from a global equation of state in the vicinity of the critical point. Specifically, a crossover thermodynamic potential is used to represent the thermodynamic data of ethylene accurately. The singularity of the rectilinear diameter very close to the critical point is reproduced using this model and the scaling laws.
