Abstract

The dissociation of 2% 1,4-dioxane dilute in krypton was studied in a shock tube, ST, using laser schlieren densitometry, LS, at 1550-2100 K and 123±2 Torr. Products were identified by ST/time-of-flight mass spectrometry. 1,4-dioxane was found to initially dissociate via C-O bond fission followed by a 2,6 H-atom transfer to the O atom at the scission site. Simulations of the LS profiles with a 72 reaction mechanism gave excellent agreement. Rate coefficients for the initial dissociation yielded k1,123Torr(T) = (2.10 ± 0.30) × 108 × exp(-15006/T) s-1. Optimization of the simulations yielded k37 = (2.25 ± 0.60) × 103 ×T3 × exp(860/T) cm3mol-1s-1 for H-abstraction from 1,4-dioxane by OH radicals.
