4-METHYLOCTANE Usage And Synthesis

Chemical Properties

Clear, colorless, watery, flammable liquid with a faint hydrocarbon odor resembling gasoline or similarly structured alkanes, e.g., 3-methyloctane.

Uses

Gasoline component; organic synthesis.

Synthesis Reference(s)

Journal of the American Chemical Society, 103, p. 7672, 1981 DOI: 10.1021/ja00415a055

Environmental Fate

Chemical/Physical. Complete combustion of 4-methyloctane in air produces carbon dioxide and water vapor. 4-Methyloctane will not hydrolyze because it does not contain a hydrolyzable functional group.
