Method for purifying dihydroxynaphthalene |
| abstract |
The invention provides a method for purifying dihydroxynaphthalene, which is capable of suppressing soft particle generation and obtaining dihydroxynaphthalene serving as a raw material of a resin and composition excellent in filterability. The method for purifying dihydroxynaphthalene includes the step of removing a sulfur content in the dihydroxynaphthalene with an adsorbent, and neutral alumina is used as the adsorbent. |
