摘要
The reaction of a typical unsaturated alcohol, 3-methyl-3-buten-1-ol (MBO331), with Cl atoms, was investigated for the first time. The reaction was investigated using discharged flow-tube coupled with electron impact mass spectrometer. The experiments were performed over the temperature range of 248 K-298 K and at pressure of 1 torr in He as the bath gas. The obtained kinetic data were used to derive the Arrhenius expression: k(1) = (3.47 +/- 1.21) x 10(-11) exp[(599 +/- 69)/T] cm(3) molecule(-1) s(-1). Finally, atmospheric lifetimes of the MBO331 with respect to OH radicals, NO3 radicals and Cl atoms have been calculated and the atmospheric implications are considered briefly.
