ABSTRACT:
An improved process for the preparation of 2,3-dibromopropionyl chloride, which comprises brominating acrylic acid, adding iron powder or an iron salt to the resultant melt, chlorinating the dibromopropionic acid obtained, and removing the volatile components. The 2,3-dibromopropionyl chloride is obtained in high yield and purity and is an intermediate for synthesising in particular reactive dyes.
