摘要：

The gas phase reactions of atomic boron with O2, SO2, CO2, and N2O have been studied using a diffusion flame technique. Atomic boron is produced in a microwave discharge of 1% B 2H6 in helium and diffuses into a chamber containing the oxidizer also diluted in helium. The temperature was approximately 300°K. The rate constants were determined from atomic absorption measurements of boron density in the flame. The rate constants for the O2 and SO 2 reactions are (9±7) XlO-12 cm3 molecule-1sec-1 and (7±5)XlO-12 cm 3 molecule-1sec-1, respectively. An upper limit of 5XlO-13 cm3 molecule-1sec-1 is estimated for the rate constants of the CO2 and N2O reactions. © 1979 American Institute of Physics.
