Using a relative rate method, rate constants for the gas‐phase reactions of 2‐methyl‐3‐buten‐2‐ol (MBO) with OH radicals, ozone, NO 3 radicals, and Cl atoms have been investigated using FTIR. The measured values for MBO at 298±2 K and 740±5 torr total pressure are: k OH =(3.9±1.2)×10 −11 cm 3 molecule −1 s −1 , k O3 =(8.6±2.9)×10 −18 cm 3 molecule −1 s −1 , k NO 3=(8.6±2.9)×10 −15 cm 3 molecule −1 s −1 , and k Cl =(4.7±1.0)×10 −10 cm 3 molecule −1 s −1 . Atmospheric lifetimes have been estimated with respect to the reactions with OH, O 3 , NO 3 , and Cl. The atmospheric relevance of this compound as a precursor for acetone is, also, briefly discussed. © 1998 John Wiley & Sons, Inc. Int J Chem Kinet: 30: 589–594, 1998
