ETHYLCYCLOPENTANE Usage And Synthesis

Chemical Properties

Colorless liquid.

Chemical Properties

Ethylcyclopentane is a colorless flammable liquid.

Physical properties

2.10(x 10^-3 atm?m³/mol) at 25 °C (approximate - calculated from water solubility and vapor pressure)

Definition

ChEBI: Ethylcyclopentane is a cycloalkane.

Hazard

Flammable, moderate fire risk; flammable limits in air 1.1–6.7%.

Environmental Fate

Chemical/Physical. Complete combustion in air yields carbon dioxide and water vapor. Ethylcyclopentane will not hydrolyze because it has no hydrolyzable functional group.
