Chem.: Organic acids exist in vegetable mold and in the ocherous deposits of ferruginous waters. They are extracted by boiling the deposit with potash, filtering, supersaturating the liquid with acetic acid, and adding acetate of copper, which gives a dark-brown precipitate containing apocrenic acid. The filtrate is saturated with ammonium carbonate, and acetate of copper again added, which gives a greenish-white precipitate containing erenic acid . The precipitates are decomposed by suspending them in water and pa ing HS gas through the liquid. Crenic acid obtained as a pale yellow powder, soluble in alcohol, but its salts are insoluble. Crenic acid has an acid, astringent taste. Its formula is supposed to be C12H1208.
