    摘要: The present invention relates to processes for separating and recovering 3-hydroxypropionic acid, comprising: (a) subjecting an aqueous solution comprising a salt of 3-hydroxypropionic acid to concentrating electrodialysis to concentrate the salt of 3-hydroxypropionic acid in the aqueous solution; and (b) subjecting the resulting concentrate to bipolar membrane electro-dialysis to convert the salt of 3-hydroxypropionic acid into the free acid of 3-hydroxypropionic acid.
