摘要

The kinetics for the reactions of C₆H₅ with phenylacetylene and styrene have been measured by CRDS in the temperature range 297-409 K under an Ar pressure of 3.6 Torr. The total rate constants can be given by the following Arrhenius expressions (in units of cm³ mol^-1 s^-1): k₁(C₆H₅ + C₆H₅C₂H) = 10^13.0±0.1 exp[-(2430 ± 150)/RT and k₂(C₆H₅ + C₆H₅C₂H₃) = 10 ^13.3±0.1 exp [-(2570 ± 180)/T]. Additional DFT and MP2 calculations have been carried out to assist our interpretation of the measured kinetic data. The addition of C₆H₅ to the terminal CH _x (x = 1 or 2) sites is predicted to be the dominant channel for both reactions. The calculated bimolecular rate constants are in reasonable agreement with experimental values for the temperature range studied.
