2-Methylbutane Usage And Synthesis
Chemical Propertiescolourless liquid with a characteristic smell
UsesSolvent, manufacture of chlorinated derivatives, blowing agent for polystyrene.
DefinitionChEBI: An alkane that is butane substituted by a methyl group at position 2.
General DescriptionWatery colorless liquid with a gasoline-like odor. Floats on water. Flammable, irritating vapor is produced. Boiling point is 82°F.
Air & Water ReactionsHighly flammable. Insoluble in water.
Reactivity Profile2-Methylbutane is a fire and explosion hazard when in contact with oxidizing agents. .
HazardHighly flammable, dangerous fire risk.
Health HazardInhalation causes irritation of respiratory tract, cough, mild depression, irregular heartbeat. Aspiration causes severe lung irritation, coughing, pulmonary edema; excitement followed by depression. Ingestion causes nausea, vomiting, swelling of abdomen, headache, depression.
Fire HazardBehavior in Fire: Highly volatile liquid. Vapors may explode when mixed with air.
Safety ProfileMddly toxic and narcotic by inhalation. See also PENTANE. Flammable liquid. A very dangerous fire and explosion hazard when exposed to heat, flame, or oxidzers. Keep away from sparks, heat, or open flame; can react with oxidizing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.
Purification MethodsStir isopentane for several hours in the cold with conc H2SO4 (to remove olefinic impurities), then wash it with H2O, aqueous Na2CO3 and H2O again. Dry it with MgSO4 and fractionally distil it using a Todd column packed with glass helices. Material transparent down to 180nm is obtained by distilling from sodium wire, and passing through a column of silica gel which had previously been dried in place at 350o for 12hours before use.
