4-Bromobutyric acid(Cas 2623-87-2) Usage
|
Synthesis |
4-Bromobutyric acid may be produced by a reaction of Y-butyrolactone with hydrogen bromide. The hydrogen bromide to be used may be gas or an aqueous Solution thereof. The reaction temperature is usually about 10 to 100°C., and the amount of hydrogen bromide to be used is usually about 1 to 10 moles per mole of Y-butyrolactone. |
