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:k1 =(3.47 ± 1.21) × 10-11 exp[(599 ± 69)/T] cm3 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.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： k1 = （3.47 ± 1.21） × 10^-11 exp[（ 599 ±69）/7] cm^3 molecule^-1 s^-1. Finally, atmospheric lifetimes of the MBO331 with respect to OH radicals, NO3 radicals and CI atoms have been calculated and the atmospheric implications are considered briefly.
