WebJun 22, 2024 · Description. Cyclopentane is used as green blowing agent and involved in the production of polyurethane insulating foam, which is used in refrigerators, freezers, water heaters, construction panels, insulated pipes and roofs. As a lubricant, it finds applications in computer hard drives and outer space equipment due to its low volatile nature. Cyclopentane (also called C pentane) is a highly flammable alicyclic hydrocarbon with chemical formula C5H10 and CAS number 287-92-3, consisting of a ring of five carbon atoms each bonded with two hydrogen atoms above and below the plane. It occurs as a colorless liquid with a petrol-like odor. Its melting point is −94 °C and its boiling point is 49 °C. Cyclopentane is in the class of cycloalkanes, being alkanes that have one or more rings of carbon atoms. It is formed by cracking greenock gang show facebook
