Method for separating and purifying hydroxynaphtalenecarboxylic acids |
| abstract |
The present invention provides a method for effectively separating independent hydroxynaphthalene-carboxylic acids by treating a mixture containing various kinds of hydroxynaphthalene-carboxylic acids with nonionic porous synthetic adsorbents having as a basic structure aromatic copolymers mainly composed of styrene and divinyl benzene or methacryl copolymers mainly composed of monomethacrylates and dimethacrylates. |
