✦ Synopsis

The thermal dccompodlion of formyl fluoride in Ar has been studed behind shock waves over the temperature range i 160-1480 K and the total density fa"ge (7.18-18.6) x IO* mol cmm3. The decomposition was monitored by means of IR em&ion from the CH stretching of the reactant and the fundamental band of the CO produced. The decomposition was found to be moleeuia~ elimination producing HF and CO end the process pr0cpede.d in the iow-pzs~~~ segion under the pxecent conditions The second-order rate constant w= expressed as k/EAr] = 1014.74 expt-35.3 kcal mol-'[RTj cm3 mol-' s-I. Applying the RRKM strong cAMon thenry, the value of the tbsesbhold energy and the eation effiideney Fyere discussed.

The thermal unimolecular decomposition of propynal was investigated behind reflected shock waves. The decomposition proceeded via the molecular path to produce acetylene and carbon monoxide. The Arrhenius expression for the high pressure rate constants is k, = 10'4.93 exp ( -7 1 kcal mol-'/RT) s-' i

The unimolecular decomposition of 1,3,5-trioxane into three formaldehyde molecules has been studied thermally at eight temperatures between 523 and 603 K using mixtures highly diluted with Ar. Under these conditions, the only decomposition product detected by means of FTIR analysis was formaldehyde.
