Control process of isomer ratio of aromatic hydroxycarboxylic acid |
| abstract |
A process for carrying out a reaction of alkali metal phenolate with carbon dioxide in an organic phosphine oxide solvent and controlling the isomer ratio of resulting aromatic hydroxycarboxylic acids by changing the mole ratio of the organic phosphine oxide to the alkali metal phenolate in the range of from 1 to 4, is disclosed. |
