Cyclopentane From Wanfeng Industrial
Dangerous situationIngestion and inhalation are moderately toxic. (2) Being flammable with greater risk of combustion. The allowable concentration in air is 600ppm (1720mg/m3) in the United States.
Harmful effects and symptoms of poisoningInhalation of high concentrations of cyclopentane can cause central nervous system inhibition, although its acute toxicity is low. Symptoms of acute exposure include excitement at first, followed by the emergence of balance disorders, and even stupor, coma. There are rarely cases of death due to respiratory failure. It has been reported that animals fed with this goods can get severe diarrhea, leading to heart, lung and liver vascular collapse and brain degeneration.
Protective measuresIt can be used for improving the production equipment. Use skin protective creams or gloves to protect the skin.
Medical careUpon regular physical examination, pay attention to the potential irritation effect of skin and respiratory tract as well as any complications of kidney and liver.
Transportation requirementsGrade I flammable liquid. Code of Hazard Regulations: 61013. The container shall be marked with a "flammable liquid" mark on transport.
Fire extinguishing agentSee “cyclohexane”.
Recommended waste disposal methodsIncineration;
Chemical propertiesIt appears as colorless liquid with a melting point of-93.9 °C, the boiling point of 49.26 ° C, the relative density of 0.7460 (20/4 ° C), the refractive index of 1.4068 and the flash point of-37 °C. It is miscible with alcohol, ether and other organic solvents, being not be easy to be dissolved in water.
Uses(1) It can be used as a solvent for solution polymerization of polyisoprene rubber and cellulose ether. It can be used as a substitute for Freon as insulation materials in refrigerators and freezers as well as foaming agents for other hard PU foams, and chromatographic analysis standards.
(2) Used as a standard substance for chromatographic analysis, solvents, engine fuels, azeotropic distillation agents.
Production methodCyclopentane is a component of the petroleum ether in the 30-60 °C boiling point range with the content being generally 5%-10%. Apply atmospheric distillation; at a 60: 1 reflux ratio and carry out at an 8m height tower; first distill out the isopentane and n-pentane; continue fractionation to obtain a cyclopentane with purity being over 98%. Cyclopentane can also be obtained through cyclopentanone reduction or cyclopentadiene catalytic hydrogenation.

Chemical Propertiescolourless liquid with a petrol-like smell
DefinitionChEBI: A cycloalkane that consists of five carbons each bonded with two hydrogens above and below the plane. The parent of the class of cyclopentanes.
General DescriptionA clear colorless liquid with a petroleum-like odor. Flash point of -35°F. Less dense than water and insoluble in water. Vapors are heavier than air.
Air & Water ReactionsHighly flammable. Insoluble in water.
Reactivity ProfileCYCLOPENTANE is incompatible with strong oxidizing agents such as chlorine, bromine, fluorine. .
Health HazardInhalation causes dizziness, nausea, and vomiting; concentrated vapor may cause unconsciousness and collapse. Vapor causes slight smarting of eyes. Contact with liquid causes irritation of eyes and may irritate skin if allowed to remain. Ingestion causes irritation of stomach. Aspiration produces severe lung irritation and rapidly developing pulmonary edema; central nervous system excitement followed by depression.
Fire HazardBehavior in Fire: Containers may explode.
