Abstract

The gas‐phase thermal decomposition rate of peroxy‐n‐butyryl nitrate (n‐C~3~H~7~C(O)OONO~2~, PnBN) has been measured at ambient temperature (296 K) and 1 atm of air relative to that of peroxyacetyl nitrate (CH~3~C(O)OONO~2~, PAN) using mixtures of PAN (14–19 ppb), PnBN (22–46 ppb), and nitric oxide (1.35–1.90 ppm). The PnBN/PAN decomposition rate ratio was 0.773 ± 0.030. This ratio, together with a literature value of 3.0 × 10^−4^ s^−1^ for the thermal decomposition rate of PAN at 296 K, yields a PnBN thermal decomposition rate of (2.32 ± 0.09) × 10^−4^ s^−1^. The results are briefly discussed by comparison with data for other peroxyacyl nitrates and with respect to the atmospheric persistence of PnBN. © 1994 John Wiley & Sons, Inc.

## Abstract The cyclic sulfenic ester 1,2‐oxathiolane (**1**) decomposes thermally (400 – 450 K) exclusively to give acrolein (**3**) __via__ 3‐mercaptopropanal (**2**) by loss of hydrogen sulfide. Isotopic labelling experiments reveal the presence of a 1,2‐oxathiolane‐thietane 1‐oxide equilibrium

## Abstract The gas‐phase thermal decomposition of 5‐ethyl‐1‐pyrroline has been studied in the temperature range 721–786 K. The decomposition appears to proceed by two pathways, one a radical route yielding pyrrole, ethylene and ethane as major products, and the other a molecular hydrogen eliminati
