Abstract
PURPOSE: To prepare the titled substance useful as a day, etc. in high yield, from 1,4-dihydroxynaphthalene, by carboxylating the starting compound with carbon dioxide gas in a solvent of the starting compound, in the presence of potassium carbonate suspended or dispersed in the solvent, in single reaction system in one step.
CONSTITUTION: The objective compound can be obtained from 1,4-dihydroxynaphthalene, by (1) dissolving the starting compound in an organic medium which can dissolve the compound, e.g. ketones, esters, ≥4C alcohols, polyhydric alcohols, etc., (2) suspending anhydrous potassium carbonate powder in the medium, and (3) subjecting to the carboxylation reaction with carbon dioxide gas under pressure and agitation at 130W200°C, pref. 140W180°C. The molar ratio of the starting raw material to potassium carbonate is pref. 1:≥1.5. The water- content of the raw material and the medium is pref. ≤0.5wt%.
