摘要：

The homogeneous unimolecular decomposition of CF3OH was studied in a quartz flow reactor with a fixed-length, variable temperature reaction zone, using chemical ionization detection of CF3OH. The pressure independent rate coefficient for the decomposition of CF,OH in N-2 was measured to be k(infinity)(T)=(3+27, -2.7) x 10(11) s(-1) exp{(-(19+/-4) x 10(3))/T}, which translates to a lifetime of greater than 10(4) years with respect to unimolecular decomposition in the atmosphere.
