Kinetic study of the reaction of chlorine atoms with 3-methyl-3-buten-1-ol

Abstract

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) × 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.
