Pm. Futerko et al., WIDE TEMPERATURE-RANGE KINETICS OF THE GAS-PHASE REACTIONS OF BCL WITH SO2, N2O, O-2, AND CO2, Journal of physical chemistry, 97(46), 1993, pp. 11950-11955
Rate coefficients for the title reactions have been measured in a high
-temperature fast-flow reactor (HTFFR). Weighted fits give for BCl + S
O2 k(470-1690 K) = 7.7 x 10(-22)(T/K)(3.0) exp(-1680 K/T) cm(3) molecu
le(-1) s(-1) and for BCl + N2O k(670-1000 K) = 5.1 X 10(12) exp(-6340
K/T) cm(3) molecule(-1) s(-1). 2 sigma accuracy limits are about +/-25
%. Model-based transition-state theory (MTST) is used to calculate rat
e coefficients for the O-atom abstraction channels of these reactions,
as well as for the previously measured BCl reactions with O-2 and CO2
. Approximate agreement between theory and experiment is obtained for
the four reactions, indicating abstraction to be dominant for each rea
ction. The reactions are compared to the corresponding AlCl reactions.
