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
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。
