There is a problem that it is not easy to isolate A from the reaction system. That is, in the reaction of potassium salt or sodium salt of α- or β-naphthol with carbon dioxide, potassium or sodium salt of K1- or 2-hydroxynaphthalene carbo/acid is first produced, but these are converted into free acid. 1-HNCA or 2-H
To isolate NCA, the general method is to add water to the reaction solution after the reaction, extract the salts with water, and then acidify the resulting aqueous phase with mineral acid. It is true. However, when a water-soluble polar solvent such as dioxane is used, adding K water to the K reaction solution will make the aqueous phase homogeneous with the reaction solvent dioxane, and the product 1- or 2-hydroquinaphthalene cargen. acid potassium or sodium
This means that the IJ salt cannot be separated from the reaction solvent. On the other hand, when a water-insoluble solvent, that is, an aromatic hydrocarbon solvent such as toluene, is used as a reaction solvent to facilitate isolation of the product, there is a problem that the reaction yield is extremely low. be.

The temperature was heated to 80°C, and while stirring, 4.41 (0.1 mol) of carbon dioxide was introduced into the reaction system at normal pressure over 1 hour to carry out the reaction, and 1- and droxynaphthalene-2- 102.6 P of a nooxane solution of potassium salt of carboxylic acid was obtained. Next, 100-water was added to this solution, but it did not separate into an aqueous phase and a solvent phase as in Example 1, but a homogeneous phase K formed. /Isolation of the acid was difficult. Therefore, dioxane bath solution 102.1 of potassium salt of 1-hydroxynaphthalene-2-cargo/acid obtained in the same manner as above was heated to distill dioxane,
A mixture of solid potassium salt of 1-hydroxynaphthalene-2-cargenic acid and unreacted potassium salt of α-na7tol was obtained, 24.39-. In this case, solid matter precipitated during the distillation, making stirring impossible. As a result, heat transfer was poor, and it took a long time to completely remove K from the zooxane. Also, because the heat transfer was not uniform, discoloration was observed due to localized heating. A mixture of the obtained potassium salt of 1-hydroxynaphthalene-2-carboxylic acid and the unreacted potassium salt of α-naphthol was dissolved in 100 d of water, and then 1 liter of 10% sulfur was added. t-added, pl-1f: 7, precipitated unreacted α-natol was filtered through F-K.
I removed 9. Further, 10% sulfuric acid was added to this p-liquid K to precipitate gray crystals. This was heated in an oven, washed with water, and then dried at 100° C. under a reduced pressure of 30 fiI{g for 12 hours to obtain 15.75' (yield: 84%) of 1-hydroxynaphthalene-2-carbic acid.
