Preparation of dialkali metal salts of aromatic hydroxycarboxylic acids |
| abstract |
Alkali metal aryloxides can be dried quickly by removing water during melting of the aryloxides. Such dry aryloxides are useful as chemical intermediates. The molten alkali metal aryloxide can be contacted with carbon dioxide to quickly produce diallyk metal salts of aromatic hydroxycarboxylic acids, which are acidified to produce the corresponding aromatic hydroxycarboxylic acids. Aromatic hydroxycarboxylic acids are useful as chemical intermediates and as monomers of polymers. Solid metal aryloxides, even when pasted, can stir the contents and react with carbon dioxide in a reactor that makes the reaction faster than conventional methods. |
