Product Name:Cyclopentene
English Name:Cyclopentene
CAS No.:142-29-0
Aliases:Cyclopentene
Molecular Formula:C5H8
Physical Properties:Molecular weight: 68.11 g/mol; appearance: colorless transparent liquid with a characteristic odor; melting point: -135°C; boiling point: 44.2°C (at standard atmospheric pressure); density: 0.774 g/cm³ (20°C); refractive index: 1.422 (20°C); flash point: -30°C (closed cup); insoluble in water, miscible with most organic solvents such as ethanol, ether, acetone; relative vapor density (air=1): 2.35; saturated vapor pressure: 75.2 kPa (20°C); contains carbon-carbon double bond, exhibits general properties of olefins, can undergo addition, oxidation, polymerization reactions, decolorizes bromine water and acidic potassium permanganate solution; stable, but flammable, forms explosive mixtures with air, extremely flammable and explosive in presence of open flames or high heat, avoid contact with strong oxidants; explosion limit: 1.4%-8.5% (by volume)
Uses:Cyclopentene is a five-membered cyclic olefin compound widely used in chemical, pharmaceutical, and material fields. As an important organic synthesis intermediate, it can be used to prepare various chemicals through addition, oxidation and other reactions, such as chlorocyclopentane via addition with hydrogen chloride. It can participate in polymerization to produce polycyclopentene, which has certain elasticity and aging resistance and is used for elastomeric materials, showing application potential in the rubber industry. It can also be used as a solvent in organic reactions or extraction processes, and serves as a raw material in pharmaceutical intermediate synthesis and gasoline additive production.
