| | 2-Chlorobutane Usage And Synthesis |
| Chemical Properties | colourless liquid | | Chemical Properties | Butyl chloride is a highly flammable, clear,
colorless liquid. | | Uses | 2-Chlorobutane is used as a solvent and intermediate in organic synthesis. Further, it is involved in the preparation of active pharmaceutical ingredients, plasticizer, rubber, resin and surfactants. | | Definition | ChEBI: 2-chlorobutane is a chloroalkane that is butane which carries a chloro group at position 2. It derives from a hydride of a butane. | | Synthesis Reference(s) | Journal of the American Chemical Society, 73, p. 2428, 1951 DOI: 10.1021/ja01150a006 | | Hazard | Flammable, dangerous fire risk. | | Flammability and Explosibility | Highlyflammable | | Safety Profile | Wdly toxic by
ingestion, inhalation, and skin contact.
Questionable carcinogen with experimental
neoplastigenic data. Dangerous fire hazard
when exposed to heat, open flame (sparks), or oxidizers. To fight fEe, use water, water
spray, fog, mist, dry chemical, alcohol foam.
When heated to decomposition it emits
toxic fumes of Cl-. See also

ALIPHATIC . | | Potential Exposure | Butyl chloride is used as a solvent; as
a medicine to control worms, and to make other chemicals | | Shipping | UN1127 Chlorobutanes require, Hazard Class: 3;
Labels: 3—Flammable liquid | | Purification Methods | Purify it in the same way as n-butyl chloride. [Beilstein 1 IV 248.] | | Incompatibilities | Vapor may form explosive mixture with
air. May accumulate static electrical charges, and may
cause ignition of its vapors. Water contact slowly forms
hydrochloric acid. Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases,
strong acids, oxoacids, epoxides, alkaline earth, and alkali
metals; finely divided metal. Attacks metals in presence of
moisture. Attacks some plastics, rubber, or coatings | | Waste Disposal | Dissolve or mix the material
with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal,
state, and local environmental regulations must be
observed. |
