Abstract: In this paper, we measured the change of partial molar free energy of various pyridine derivatives (△G'or △G function) and its difference (δ(△G')) on capillary column coated with OV-101 and OV-17 The result indicates that the same substituent in different positions of hete-rocyclic ring provides different energiesCalculated by this method, the △G values and the retention index of the unknown are in good agreement with the experimental values, and this calculating method is of greatly practical significance.

Key words: Pyridine derivative, Partial molar free energy, Retention index
