The thermal decomposition of trifluoroacetaldehyde at temperatures f 471 to 519°C has been studied by measuring the rates of formation of CF 3 H and C 2 F 6 . It is concluded that the high‐pressure reaction mechanism involves a Rice‐Herzfeld reaction scheme with first‐order initiation and second‐order termination via CF 3 combination. However, a falloff in reaction rates is observed at pressures below 100 mmHg. The Arrhenius parameters of the three rate constants corresponding to the overall reaction, the initiation reaction, and an abstraction reaction have been evaluated.
