Rate Constants for the Gas-Phase Reactions of Hydroxyl Radicals with Tetramethyllead and Tetraethyllead

Publikation: Bidrag til tidsskriftTidsskriftartikelForskningfagfællebedømt

Rate constants for the reactions of OH radicals with (CH3)4Pb and (C2H5)4Pb have been determined at 298 ± 2 K and a total pressure of approximately 1 atm. Rate data were obtained by using both the absolute rate technique of pulse radiolysis combined with kinetic spectroscopy and a conventional photolytic relative rate method. Rate constants were also obtained for the analogous reactions with (CH3)4C and (C2H5)4C for comparison purposes. The results are discussed in terms of structure-reactivity relationships. Values of the rate constants (10-12 cm3 molecule-1 s-1) are [formula omited].
