Rate constants for the gas phase reactions of OH with C 5 through C 7 aliphatic alcohols and ethers: Predicted and experimental values

Rate constants for the gas phase reactions of OH with C 5 through C 7 aliphatic alcohols and... Absolute rate constants were determined at 298 K for the gas phase reactions of hydroxyl radicals with several C5 through C7 aliphatic alcohols and ethers using the flash photolysis resonance fluorescence technique. The values obtained (in units of 10−12 cm3 molecule−1 s−1) were: 3‐methyl‐2‐butanol, (12.4 ± 0.7); 2‐pentanol, (11.8 ± 0.8); 3‐pentanol, (12.2 ± 0.7); cyclopentanol, (10.7 ± 0.7); 1‐hexanol, (12.4 ± 0.7); 2‐hexanol, (12.1 ± 0.7); 1‐heptanol, (13.6 ± 1.3); methyl‐n‐butylether, (16.4 ± 0.6); ethyl‐n‐butylether, (22.8 ± 0.9); ethyl‐t‐butylether, (8.12 ± 0.32); and methyl‐t‐amylether, (7.91 ± 0.42).

Abstract

Absolute rate constants were determined at 298 K for the gas phase reactions of hydroxyl radicals with several C5 through C7 aliphatic alcohols and ethers using the flash photolysis resonance fluorescence technique. The values obtained (in units of 10−12 cm3 molecule−1 s−1) were: 3‐methyl‐2‐butanol, (12.4 ± 0.7); 2‐pentanol, (11.8 ± 0.8); 3‐pentanol, (12.2 ± 0.7); cyclopentanol, (10.7 ± 0.7); 1‐hexanol, (12.4 ± 0.7); 2‐hexanol, (12.1 ± 0.7); 1‐heptanol, (13.6 ± 1.3); methyl‐n‐butylether, (16.4 ± 0.6); ethyl‐n‐butylether, (22.8 ± 0.9); ethyl‐t‐butylether, (8.12 ± 0.32); and methyl‐t‐amylether, (7.91 ± 0.42). These results are discussed in terms of group reactivities in such molecules and are compared with values estimated from an additive structure‐reactivity index.
