Chemical properties
CLEAR COLOURLESS LIQUID
The Uses of 1-Chloro-2-methylpropane
1-Chloro-2-methylpropane is used to prepare an organometllic compound, isobutyllithium by reacting with lithium using petroleum ether as a solvent.
General Description
The gas-solid virial co-effiicent of 1-chloro-2-methylpropane was determined. The infrared and Raman spectra of 1-chloro-2-methylpropane was studied.
Synthesis
1-Chloro-2-methylpropane can be synthesized in a substitution reaction by reacting isobutanol with hydrochloric acid, catalyzed by concentrated sulfuric acid:
(CH3)2CH-CH2-OH + HCl → (CH3)2CH-CH2-Cl
Purification Methods
Use the same methods as described under isoamyl chloride.[Beilstein 1 IV 287.]
