Title:
PROCESS FOR RECOVERY OF 3-HYDROXYPROPIONIC ACID AND 3-HYDROXYPROPIONIC ACID-CONTAINING SLURRY COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/096366
Kind Code:
A1
Abstract:
The present invention relates to a process for recovery of 3-hydroxypropionic acid, a precipitate prepared in the process for recovery of 3-hydroxypropionic acid, and a slurry composition containing 3-hydroxypropionic acid, the method comprising the steps of: forming crystals of a 3-hydroxypropionic acid salt in a concentrate containing 3-hydroxypropionic acid in the presence of an alkali metal salt; preparing a solution containing the crystals of the 3-hydroxypropionic acid salt, separated from the concentrate; and injecting ammonia into the solution containing the crystals of the 3-hydroxypropionic acid salt.
