반응 단계
The procedure of Example 1 is followed in every detail except that a mixture of 2-hydroxynaphthalene (83 grams; 0.576 mole), 45% potassium hydroxide (69.7 grams; 0.559 mole), and potassium carbonate (20 grams; 0.145 mole) is employed initially, the dehydrated reaction mixture is heated under 60 psi of carbon dioxide for 10 hours, and the aqueous phase is washed twice with 100-ml portions of isopropylnaphthalene at 85°-95° C. There is obtained 25.5 grams of 6-hydroxy-2-naphthoic acid (48.1% of theoretical), and 4.6 grams of 3-hydroxy-2-naphthoic acid.
