Ciklopentan (CYP/CP5) Cas št.:287-92-3 vroče prodaja

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 has a melting point-94.4 degree , boiling point of 49.3 degree , relative density of 0.7460 and the refractive index of 1.4068. 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. The carbon-carbon-carbon bond angle is close to 109 degree 28 ' with the molecular tension not big and the ring being relatively stable. It has a similar chemical property as alkanes. The lethal concentration in the air for the rats was 3.8 × 10-2. It exhibits red yellow color when having reaction with fuming sulfuric acid while generating nitro cyclopentane and glutaric acid through reaction with nitric acid. Method: it can be obtained from the petroleum ether distillate, through high-pressure cracking on the cyclohexane in the presence of aluminum or catalytic hydrogenation of cyclopentene and cyclopentadiene.

Ciklopentan se uporablja kot zeleno pihalno sredstvo in vključen v proizvodnjo poliuretana izolacijo peno % 2c ki se uporablja v hladilnikih % 2c zamrzovalnikih % 2c voda grelniki % 2c gradbeništvo plošče % 2c izolirane cevi in strehe. Kot a mazivo% 2c it najde aplikacije v računalniku trdih pogonih in zunanjem prostoru opremi zaradi njegove nizke hlapne narave. To je široko uporabno v pripravi smole 2c lepila in farmacevtsko vmesno. To je je an dodatek v bencin. Ker je to a brez halogenov brez spojina in ima ničelni ozon tanjšanje potencial 2c to nadomešča konvencionalno uporabljeno kloro fluoro ogljik (CFC) v hlajenje in toplotna izolacija.
