Method for producing dihydroxyphthalic acids |
| abstract |
PROBLEM TO BE SOLVED: To provide a method capable of producing dihydroxyphthalic acids at a relatively short reaction time at a moderate reaction pressure which is not particularly high. A dihydric phenol is brought into contact with carbon dioxide in the presence of an alkali metal carbonate and / or an alkali metal bicarbonate and a lithium compound to dicarboxylate the dihydric phenol. [Selection figure] None |
