    環己烷之功用工業上為製造adipic acid的原料,而有機實驗室則常用的跑TLC片或萃取溶劑

    Commercially most of cyclohexane produced is converted into cyclohexanone-cyclohexanol mixture (or "KA oil") by catalytic oxidation. KA oil is then used as a raw material for adipic acid and caprolactam. Practically, if the cyclohexanol content of KA oil is higher than cyclohexanone, it is more likely(economical) to be converted into adipic acid, and the reverse case, caprolactam production is more likely. Such ratio in KA oil can be controlled by selecting suitable oxidation catalyst. Some of cyclohexane is used as an organic solvent.

    環戊烷之功用

    Cyclopentane is used in the manufacture of synthetic resins and rubber adhesives and also as a blowing agent in the manufacture of polyurethane insulating foam, as found in may domestic appliances such as refrigerators and freezers, replacing environmentally damaging alternatives such as CFC-11 and HCFC-141b[1]

    More advanced technologies, such as computer hard drives and outerspace equipment employ multiply-alkylated cyclopentane (MAC) lubricants because of their extremely low volatility
