2-Chloro-2-methylpropane Usage And Synthesis

Chemical Properties

colourless liquid

Uses

  • 2-Chloro-2-methylpropane is an alkylating agent that is used to functionalize molecules with tert-butyl group.
  • It serves as an effective chlorinating agent, in combination with the ionic liquid, 1-butyl-3-methylimidazolium bromide for converting alcohols into chlorides.
  • It can also be used to prepare tert-butyl ethers by treating with corresponding alcohols.

Safety Profile

Questionable carcinogen with experimental neoplastigenic data. Dangerous fire hazard when exposed to heat, flame (sparks), and oxidlzers. To fight fue, use water, spray, fog, alcohol foam, dry chemical. When heated to decomposition it emits toxic fumes of Cl-. See also CHLORINATED HYDROCARBONS, ALIPHATIC.

Purification Methods

Purification methods commonly used for other alkyl halides lead to decomposition. Some impurities can be removed by photochlorination with a small amount of chlorine prior to use. The liquid is washed with ice water, dried with CaCl2 or CaCl2 + CaO and fractionally distilled. It has been further purified by repeated fractional crystallisation by partial freezing.
