Reaction Steps
The procedure of Production Example 3 was repeated except that phenol was replaced with 2,3dihydroxynaphthalene, the 35% concentrated hydrochloric acid was replaced with 0.1 ml of phosphoric acid, and the reaction solution to be subjected to reflux was-added with 100 g of acetone and then was heated under reflux, to give a 2,3-dihydroxynaphthalene-formaldehyde condensate.
