The reaction is particularly facile with di- and tri-hydric phenols. Thus p-resorcylic acid is readily obtained by passing carbon dioxide through a boiling aqueous solution of the potassium or sodium salt of resorcinol ... [Pg.754]

The combined yield of crude acid (260-270 g.) is dissolved in 11. of water, boiled with about 25 g. of Norite, filtered through a heated filter, and crystallized by placing in an ice-salt freezing mixture and stirring vigorously. A finely crystalline, colorless product is obtained in this way. If it is allowed to crystallize slowly the crystals are somewhat colored. The yield of pure resorcylic acid melting at 216-217° is 160-170 g. (57-60 per cent of the theoretical amount) (Note 3). [Pg.111]
