2-Chlorobutane Chemical Properties,Uses,Production

Chemical Properties

Butyl chloride is a highly flammable, clear, colorless liquid.

Chemical Properties

colourless liquid


Organic synthesis.


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.

Synthesis Reference(s)

Journal of the American Chemical Society, 73, p. 2428, 1951 DOI: 10.1021/ja01150a006


Flammable, dangerous fire risk.

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 E CHLORINATED HYDROCARBONS, ALIPHATIC .

Potential Exposure

Butyl chloride is used as a solvent; as a medicine to control worms, and to make other chemicals


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.]


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.
