Tert- butyl bromide is an organic compound having a tertiary carbon atom and a bromide as a substituent. The connection counts as alkyl bromide to the halocarbons and is used for example as a starting material for the synthesis. Isomers, 1- bromobutane, 2 -bromobutane and the 1-bromo- 2-methylpropane, which together form the group of butylbromide.

Production and representation

One way to represent the reaction of tert- butanol with hydrogen bromide. Another is the reaction of isobutane with bromine.

Properties

Tert- butyl bromide is a highly volatile, colorless liquid with a characteristic odor, is practically insoluble in water. It transforms when mixed with water quickly to tert- butanol and hydrogen bromide. Solving it in methanol, it disappears quickly and it forms 2-methoxy -2-methyl propane ( which is formed by solvolysis ) and 2- methylpropene. The technical product is stabilized with potassium carbonate.
