3,3,4,4,5,5-hexafluorocyclopentene (6FE), 1,3,3,4,4,5,5-heptafluorocyclopentene (7FE) and octafluorocyclopentene (8FE) are considered as new generation of potential chlorofluorocarbons substitutes. To investigate the thermostabilities, tubular furnace experiments were designed over temperature range of 500-850℃. The results show that 6FE, 7FE and 8FE are all stable below 650 ℃, thus have good stabilities in common storage and practical use condition. Furthermore, considering the short atmospheric lifetimes (several months), low global warming potentials (GWPs, less than 119) and zero ozone depletion potentials (ODPs), the compounds seem no big influences on the climate change.

3,3,4,4,5,5-六氟环戊烯（6FE），1,3,3,4,4,5,5-七氟环戊烯（7FE）和八氟环戊烯（8FE）被视为新一代潜在的氯氟烃替代物。为了研究热稳定性，设计了在500-850℃温度范围内的管式炉实验。结果表明，6FE，7FE和8FE在650℃以下均稳定，因此在一般贮存和实际使用条件下具有良好的稳定性。此外，考虑到较短的大气寿命（数月），较低的全球变暖潜能值（GWP，低于119）和零臭氧消耗潜能值（ODP），这些化合物似乎对气候变化影响不大。
