Abstract
Mono-hydroxy mono-carboxylic acids of the benzene and naphthalene series are obtained by the action of carbon dioxide on a dry solution of an alkali metal phenolate or naphtholate in a dialkyl ketone which is liquid at ordinary temperatures and has a boiling point of at least 75 DEG C. Various substituents may be present in the nucleus but at least one of the positions ortho to the hydroxy group is preferably unsubstituted. Methyl isobutyl ketone is the preferred solvent for naphthols and di-isobutyl ketone for phenol itself, these being substantially immiscible with water. The reaction is preferably carried out at least 10 degrees below the boiling point of the ketone, carbon dioxide being passed in and the di-salt of the hydroxy acid being precipitated. This is filtered off and a further portion of alkali and phenol or naphthol added, giving after dehydration a solution which may be again reacted with carbon dioxide. The free hydroxy-acid is liberated from the salt and isolated in various ways. Examples show the preparation of 1-hydroxy-2-naphthoic acid, 2-hydroxy-1-naphthoic acid, salicylic acid and 5-benzyl-salicylic acid. Specifications 384,619, 460,282, 483,795 and 511,393 are referred to. Solutions of alkali phenolates or naphtholates in dialkyl ketones are obtained by mixing a solution of the phenol or naphthol in the ketone with alkali metal, or concentrated aqueous alkali; in the latter case the water is removed by distillation. If the ketone is substantially immiscible with water, e.g. methyl isobutyl ketone, the distillate is separated and the ketone layer returned to the reaction vessel. When using water-soluble ketones such as methyl ethyl ketone, an azeotrope distils and fresh dry ketone must be added to replace that removed.
