The perturbation theories of fluids allow to describe the behaviour of real gases and liquids, i.e., of systems with relatively complicated intermolecular interactions, on the basis of thermodynamic and distribution functions of a simpler system chosen as a reference. Hence the perturbation methods are analogous to classical thermodynamic treatments which employ, for the description of real systems, appropriately selected standard states together with expressing the excess functions through expansions; for a method to be successful, the proper choice of the reference and a knowledge of its behaviour as accurately as possible are extremely important. Recently there has been shown no interest in the cyclic molecules because of their complexity to describe the thermodynamic behaviour. In the present theory we made attempts to apply perturbation theory to cyclic hexamers which could be expected to be useful in the petroleum chemical industry where the aromatic chemicals are commonly treated. |
