1-chloro-2-methylpropane (also isobutyl chloride ) is a chemical compound from the group of saturated chlorinated hydrocarbons and one of the isomeric butyl chlorides .
Extraction and presentation
1-Chloro-2-methylpropane can be obtained by chlorination of isobutane , a mixture with tert-butyl chloride being formed. The ratio of the two compounds depends on the temperature. At room temperature 64% 1-chloro-2-methylpropane is produced, at 600 ° C it is 80%.
It is obtained isomer-free under mild conditions by reacting 2-methyl-1-propanol with triphenylphosphine dichloride .
properties
1-chloro-2-methylpropane is a volatile, colorless liquid with a characteristic odor, which is practically insoluble in water.
use
1-Chloro-2-methylpropane is used as an intermediate in organic chemistry (for example for the production of methacrylonitrile ).
safety instructions
The vapors of 1-chloro-2-methylpropane can form an explosive mixture with air ( flash point approx. −21 ° C, ignition temperature 395 ° C).
