G. Fantechi et al., DETERMINATION OF THE RATE CONSTANTS FOR THE GAS-PHASE REACTIONS OF METHYL BUTENOL WITH OH RADICALS, OZONE, NO3 RADICALS, AND CL ATOMS, International journal of chemical kinetics, 30(8), 1998, pp. 589-594
Using a relative rate method, rate constants for the gas-phase reactio
ns of 2-methyl-3-buten-2-ol (MBO) with OH radicals, ozone, NO, radical
s, 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) x 10(-11) cm(3) molecule(-1) s(-1), k(o3) = (8.6 +/- 2.
9) x 10(-18) cm(3) molecule(-1) s(-1), k(No3) = (8.6 +/- 2.9) x 10-(15
) cm(3) molecule-(1) s(-1), and k(Cl) = (4.7 +/- 1.0) x 10(-10) cm(3)
molecule(-1) s(-1). Atmospheric lifetimes have been estimated with res
pect to the reactions with OH, O-3, NO3, and Cl. The atmospheric relev
ance of this compound as a precursor for acetone is, also, briefly dis
cussed. (C) 1998 John Wiley & Sons, Inc. Int J Chem Kinet: 30. 589-594
