응용 분야 · 2건

용도Cyclopentene is a cycloalkene that is cyclopentane having one endocyclic double bond. Vapors heavier than air. Inhalation of high concentrations may be narcotic. Used to make rubber and plastics. Neopentyl phosphine ligand catalyzed Heck coupling of cyclopentene has been reported. Mechanism of reaction of ground state oxygen atom with cyclopentene has been investigated. Homopolymerization of cyclopentene has been reported. Photocatalytic oxidation of cyclopentene over various titanium(IV) oxide catalyst has been reported. Cyclopentene was used to investigate the [2+2] cycloaddition of diamond (001) surfaces with alkene.

일반 설명Cyclopentene appears as a colorless liquid. Less dense than water and insoluble in water. Flash point below 0°F. Vapors heavier than air. Inhalation of high concentrations may be narcotic. Used to make rubber and plastics.

제조 방법 · 1건

Cyclopentene is synthesized by selective hydrogenation of cyclopentadiene or by dehydration of cyclopentanol. It is produced industrially in large amounts by steam cracking of naphtha. Cyclopentene is present in coal tar, cigarette smoke, and automobile emissions.
