| titleOfInvention | Production method of 3-hydroxyadipic acid-3,6-lactone |
| abstract | An object of the present invention is to recover easily from an aqueous solution containing 3-hydroxyadipic acid by a method for producing 3-hydroxyadipic acid-3,6-lactone comprising the following steps (A) and (B) as 3-hydroxyadipic acid-3,6-lactone of ε-caprolactam synthesis raw material. (A) Step (B) of adding an acid to an aqueous solution containing 3-hydroxyadipic acid to obtain an aqueous solution containing 3-hydroxyadipic acid-3,6-lactone A process for obtaining a 3-hydroxyadipic acid-3,6-lactone extract by contacting an aqueous solution of -hydroxyadipic acid-3,6-lactone with an extraction solvent that can be phase-separated from the solution. |
