Merck: 14,2741

BRN: 1900195

Henry's Law Constant: 0.164, 0.240, and 0.300 at 27.9, 35.8, and 45.0 °C, respectively (dynamic headspace, Hansen et al., 1995)

Exposure limits: TLV-TWA 600 ppm (～1720 mg/m³) (ACGIH).

Dielectric constant: 1.9（20℃）

Stability:: Stable. Highly flammable. Note low flash point and wide explosion limits. Incompatible with strong oxidizing agents. Floats on water, so water is of limited value in putting out fires involving this material.

LogP: 3 at 20℃

Use

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. It is widely useful in the preparation of resin, adhesives and pharmaceutical intermediate. It is an additive in gasoline. Since it is a halogen free compound and has zero-ozone depletion potential, it replaces the conventionally used chloro fluoro carbon (CFC) in refrigeration and thermal insulation.
