DL-2-Bromopropionic(Cas 598-72-1) Usage
|
Preparation
|
2-Bromopropionic acid is obtained by bromination of propionic acid. Add propionic acid and phosphorus trichloride to the reaction kettle, keep the temperature at 80°C, slowly add bromine to the reaction solution dropwise, and heat up to 85°C after the addition of bromine, and raise the temperature to 100°C when the color of bromine disappears completely, it takes about 2~3h, and then the bromine and hydrobromic acid are recovered under reduced pressure, and then the finished product is obtained by distillation under reduced pressure. |
|
Application
|
2-bromopropionic acid is an organic synthesis intermediate, used in the production of herbicides quizalofop-ethyl, napropamide, fenthiaprop and fungicides metalaxyl, benalaxyl, procymidone, etc., used in the synthesis of pharmaceutical intermediates body alanine. |
