What is ETHYLCYCLOPENTANE?
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.
