Abstract
For systems of Kihara molecules with circular cores, the values of the redu ced critical constants were determined from the fourth-order virial expansi on as functions of the core diameter/thickness ratio. From expressions for the reduced functions both for the oblate and prolate shapes, the values of critical constants of four cyclic hydrocarbons and four branched alkanes w ere evaluated and compared with the experimental data and values obtained f rom the perturbation theory.
