Title:
METHOD FOR COLLECTING ALKALI METAL SALT HYDRATE AND 3-HYDROXYPROPIONIC ACID
Document Type and Number:
WIPO Patent Application WO/2023/096457
Kind Code:
A1
Abstract:
The present invention relates to a method for collecting an alkali metal salt hydrate and 3-hydroxypropionic acid, comprising the steps of: forming a crystal of 3-hydroxypropionate in a concentrated solution containing 3-hydroxypropionic acid in the presence of an alkali metal salt, and isolating same; and adding an acid to an aqueous solution containing the isolated crystal of a 3-hydroxypropionate, thereby forming an alkali metal salt hydrate and 3-hydroxypropionic acid and isolating same.
