Abstract
|
|
|
|
The solubility of i-butyl bromide in nitrobenzene have been measured at 19, 25 and 40℃ in the presence and absence of gallium bromide. In the presence of gallium bromide, 1 : 1 complex, i-C4H9Br·GaBr3 is formed in the solution. The instability constant K of the complex formation was evaluated from the following equilibrium equation. i-C4H9Br·GaBr3 ↔ C4H9Br + 1/2Ga2Br6. From these result, it seems that the stabilities of the complex formation, gallium bromide with alkyl bromide, are directly related with those of the carbonium ions of alkyl bromide.
