Thank you very much for your interest in our products. If you have any inquiry needs or further questions, please feel free to contact me at wendy@puqichen.com. We look forward to establishing a business relationship with you and providing you with the best products and services.

Here's a brief introduction to CP.

Cyclopentane, also known as "pentamethylene", is a kind of cycloalkane with the

formula of C5H10. It has a molecular weight of 70.13. It exists as a kind of flammable liquid. It is soluble in alcohol, ether and hydrocarbons and is not soluble in water. Cyclopentane is not a planar ring and has two conformations: envelope conformations and semi-chair conformations. It exhibits red yellow color when having reaction with fuming sulfuric acid while generating nitro cyclopentane and glutaric acid through reaction with nitric acid.

APPLICATION

Cyclopentane as a new type of foam polyurethane foam, used to replace the destruction of the atmospheric ozone layer of chlorofluorocarbons(CFCS), is now widely used in the production of fluorine-free refrigerator, freezer industry and cold storage, pipeline insulation and other fields, CFCs and HCFCs will soon be banned ad the ODS deadline is approached by the Montreal Convention, and cyclopentane will become the protagonist of the polyurethane foaming filed.
