Document Type and Number:
WIPO Patent Application WO/2023/096456
Kind Code:
A1
Abstract:
The present invention relates to: a crystal of 3-hydroxypropionic acid salt which includes an alkali metal salt of 3-hydroxypropionic acid or a hydrate thereof, and has a first peak at a predetermined diffraction angle (2θ±0.2°) of an X-ray diffraction spectrum (XRD); a method for producing same; and a process for recovering 3-hydroxypropionic acid.
