Method for producing hydroxycarboxylic acid |
| abstract |
Provided is a method for producing a hydroxycarboxylic acid, which comprises a step of removing impurities contained in a solution containing hydroxycarboxylic acid (excluding lactic acid). Solution A includes a step A in which a hydroxycarboxylic acid (excluding lactic acid) -containing solution such as glycolic acid, 3-hydroxybutyric acid and malic acid is filtered through a nanofiltration membrane to recover hydroxycarboxylic acid from the permeate side. And a method for producing a hydroxycarboxylic acid. The pH of the hydroxycarboxylic acid-containing solution leading to the nanofiltration membrane in Step A is 2 or more and 5 or less. [Selection figure] None |
