実験手順

Crude tetrapotassium 1,3,5,7-naphthalenetetracarboxylate obtained in Example 13 was again dissolved in water, and the solution was acidified with hydrochloric acid to an acidity lower than pH 1 to form free crude 1,3,5,7-naphthalenetetracarboxylic acid. The product was separated and dried to form crude 1,3,5,7-naphthalenetetracarboxylic acid as shown in Table 7.
