Rates of reaction between the nitrate radical and some unsaturated alcohols

Abstract

Rate coefficients for nitrate radical gas-phase reactions with prop-2-en-1-01 (allyl alcohol), but-I -en-3-ol, and 2-methylbut-3-en-2-01 have been determined. Both absolute (fast flow discharge with diode laser detection of NO,) and relative (batch reactor and FTIR spectroscopy) rate techniques were used to measure the rate coefficients The rate coefficients at 294 K are.[ 1 3 2 0 2 ) X IO-l4, ( I .2 ? 0 3 ) X IO-l4, and ( 2 I ? 0 3) X cm3 molecule-I s-' for prop-2-en-1-01, but-I -en-3-ol, and 2-methylbut-3-en-2-01, respectively The activation energy for reaction of NO., with prop-2-en-1-01 was determined to 2 8 ? 2.5 k] mol-I in the temperature range between 273 and 363 K . The atmospheric importance of unsaturated alcohols and structure-reactivity considerations are also discussed 0 1996 john Wiley t Sons. Inc

Rate constants for the gas-phase reactions of OH radicals with a series of unsaturated alcohols

“…In the troposphere, these and other unsaturated alcohols react with OH radicals [5 -8], NO 3 radicals [7,9,10], and O 3 [7,11 -13], with the O 3 and daytime OH radical reactions being calculated to dominate as the tropospheric Correspondence to: R.

To date, rate constants for the OH radical reactions with unsaturated alcohols are available only for allyl alcohol [5] and 2-methyl-3-buten-2-ol [6 -8], with the available rate constant for allyl alcohol being at 440 K. In this work, we have used a relative rate method to measure rate constants at 296 Ϯ 2 K for allyl alcohol, 3-buten-1-ol [CH 2 " CHCH 2 CH 2 OH], 3-buten-2-ol [CH 2 " CHCH(OH)CH 3 ], and 2-methyl-3-buten-2-ol.…”

“…Following the observation of MB emission in pine forest by Goldan et al (1993) [25], several studies on the atmospheric chemistry of this BVOC alcohol have been actively carried out [29][30][31][32][33][34][35]. Harley et al…”

“…(1998) claimed that the major photochemical sink for MB [32] or with NO 3 [33,34] imply significantly longer MB lifetimes with respect to these destruction processes. Further reaction chamber experiments [29,30] indicate that the MB-OH reaction leads to the production of acetone, glycol aldehyde, formaldehyde, and presumably 2-hydroxy-2-methylpropanal.…”
