摘要
The thermodynamic properties and molecular volumes (Vm) of 76 polychlorophe- nazines (PCPZs) have been calculated at the B3LYP/6-31G* level by using density functional theory. The isodesmic reactions were designed to calculate standard enthalpy of formation (△fHθ) and standard free energy of formation (△fGθ) of PCPZ congeners. According to the relative magnitude of their △fGθ, the order of relative stability of PCPZ congeners was theoretically proposed. Comparing the results with those of polychlorinated dibenzo-p-dioxin (PCDD) isomers, it was found that Sθ, △fHθ, △fGθ, Vm and the order of relative stability of PCPZ congeners were quite similar to those of PCDDs.
