GENERAL DESCRIPTION: <\/b><\/strong><\/p>\n

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<\/p>\n

reaction with nitric acid\u3002<\/p>\n

Application scope <\/b><\/strong><\/p>\n

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,<\/p>\n

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 field.<\/p>\n

 <\/p>\n

Physical and chemical properties and main hazards <\/b><\/strong><\/p>\n

This product has a simple asphyxiation and paralysis. People have short-term contact and do not cause symptoms. High concentration requires wearing a self-priming gas mask to avoid ingestion.<\/p>\n

\u00a0<\/b><\/strong><\/p>\n

\u00a0<\/b><\/strong><\/p>\n

Safety measures and precautions for carriage by ships <\/b><\/strong><\/p>\n

The railway transportation time limit of this product is to be shipped by the pressure- resistant liquefied gas enterprise self-provided tanker, and it must be reported to the relevant department for approval before shipment. Mixing with oxidants, halogens, etc. is strictly prohibited. Summer should be transported in the morning and evening toprevent sun exposure. Keep away from fire and heat when you stop. When transporting by road, follow the prescribed route and do not stay in residential areas and densely populated areas.<\/p>\n

\u00a0<\/b><\/strong><\/p>\n

Emergency medical treatment <\/b><\/strong><\/p>\n
