Process for the Production of a Stable Non-alcoholic Solution of Iron-peptone or Iron-manganese-peptone

20,273. Bromhead, S. S., [Chemische Fabrik Helfenberg]. Sept. 20. Peptones.-Relates to the preparation of non- alcoholic solutions of iron-peptones and ironmanganese-peptones suitable for use as medicines in cases of chlorosis, anµmia, and the like. A solution of ferrum peptonatum, or ferromanganese peptonatum, slightly acidified with hydrochloric acid, is cooled to 0‹ C. and impregnated with carbon dioxide under pressure. The solution is then kept in airtight bottles for some months. An unstable combination of peptone and carbonic acid forms. The carbonic acid tends to preserve the liquid from decomposition.
