Abstract
Relative rate constants for reaction of monomethylamine and trimethylamine with boron trifluoride are reported for the pressure range 0.04-600 Torr. The limiting ratio at low pressure is about 0.836, and the extrapolated high-pressure ratio is of the order 4. The half-pressure for quasi-bimolecular behavior of the monomethylamine-boron trifluoride system is in the vicinity of 70 Torr. When the data are combined with those of Kistiakowsky, et al., individual pressure-dependent rate constants can be estimated. The amine-BF_3 series has loose activated complexes and low energy for redistribution among internal modes, making it an unusual candidate for theoretical unimolecular study.
