ChEBI: An alkylbenzene that is benzene substituted by a butan-2-yl group.
Synthesis Reference(s)
Journal of the American Chemical Society, 106, p. 158, 1984 DOI: 10.1021/ja00313a032
Hazard
Toxic by ingestion.
Safety Profile
Moderately toxic by ingestion. A skin and eye irritant. Flammable liquid when exposed to heat or flame. To fight fire, use foam, CO2, dry chemical, water spray or mist. Incompatible with oxidzing materials. When heated to decomposition it emits acrid smoke and fumes.
Environmental Fate
Chemical/Physical. sec-Butylbenzene will not hydrolyze because it has no hydrolyzable functional group (Kollig, 1995).
