Zusatz zum Patent 264390.*)Addition to patent 264390. *)
Patentiert im Deutschen Reiche vom 16. März 1913 ab. Längste Dauer: 21. Februar 1928. Patented in the German Empire on March 16, 1913. Longest duration: February 21, 1928.
In. weiterer Ausbildung des durch Patent 2643Γ90 und dessen Zusatz 264391, Kl. 12 p, geschützten Verfahrens zur Darstellung der Ferrosalze der Glutaminsäure und ihres Anhydrids, der 2-Pyrrolidon-5-carbonsäure, welche man durch Kochen dieser Säuren mit metallischem Eisen unter Luftabschluß erhält, wurde gefunden, daß man ganz allgemein nach dieser Methode zu Ferroverbindungen von Monoaminosäuren gelangen kann.In. further training of the patent 2643Γ90 and its addition 264391, class 12 p, protected process for the preparation of the ferrous salts of glutamic acid and its anhydride, the 2-pyrrolidone-5-carboxylic acid, which can be obtained by boiling these acids with metallic Obtaining iron in the absence of air, it has been found that one generally after this Method can get to ferrous compounds of monoamino acids.
Bei genügend langem Kochen der Aminosäuren unter Luftabschluß mit metallischem Eisen erhält man Eisenverbindungen, welche den für das entsprechende Ferrosalz notwendigen Gehalt an Eisen aufweisen. Wird die Reaktion vorzeitig abgebrochen, so gelangt man zu Verbindungen· mit weniger als dem für die Ferrosalze erforderlichen Eisengehalt. Es liegen hier wahrscheinlich Gemenge der Aminosäuren mit ihren Ferrosalzen vor.If the amino acids are cooked for a long enough time in the absence of air with metallic Iron you get iron compounds, which are necessary for the corresponding ferrous salt Have iron content. If the reaction is terminated prematurely, this is achieved one to compounds · with less than the iron content required for the ferrous salts. There is probably a mixture of amino acids with their ferrous salts.
3 Teile Histidin (ß-Imidazolyl-a-aminopropionsäure) werden 12 Stunden mit 5 Teilen Eisenstaub im Kohlensäurestrom gekocht. - Die unter Luftabschluß filtrierte Lösung gibt beim Eindampfen ein schwach gelblich gefärbtes Salz. Die Eisenbestimmung ergab folgenden Wert:3 parts of histidine (ß-imidazolyl-a-aminopropionic acid) are boiled for 12 hours with 5 parts of iron dust in a carbonic acid stream. - The Solution filtered in the absence of air gives a pale yellowish colored salt on evaporation. The iron determination gave the following value:
0,2532 g Substanz hinterließ beim Glühen 0,0528 g Fe2 O3.0.2532 g of substance left 0.0528 g of Fe 2 O 3 on the glow.
Berechnet: 15,38 Prozent Fe. (C6H8O2N3).2Fe: Calculated: 15.38 percent Fe. (C 6 H 8 O 2 N 3 ). 2 Fe:
Gefunden: 14,60 Prozent Fe. Found: 14.60 percent Fe.

10 Teile Alanin werden mit 10 Teilen Eisenstaub während 20 Stunden am Rückflußkühler unter Einleiten von Kohlensäure gekocht. Die unter den gleichen Bedingungen wie im Beispiel ι zur Trockne gedampfte Reaktionsflüssigkeit liefert eine Eisenverbindung mit 12,43 Prozent Eisen.10 parts of alanine are mixed with 10 parts of iron dust boiled for 20 hours on the reflux condenser while passing in carbonic acid. the Reaction liquid evaporated to dryness under the same conditions as in Example ι provides an iron compound with 12.43 percent iron.
Auf gleiche Weise kann man Ferroverbindungen anderer Aminosäuren sowie von Aminosäuregemischen und Peptonen erhalten.Ferro compounds of other amino acids and mixtures of amino acids can be prepared in the same way and get peptones.
30 g Pepton aus Pflanzeneiweiß (Gliadin) werden in Wasser gelöst und mit 15 g Eisenfeilspänen unter Einleitung von Kohlensäure längere Zeit gekocht. Die Lösung wird filtriert und im Vakuum eingedampft. Der Rückstand besteht aus einer pulverisierbaren, wenig hygroskopischen gelbbraunen Masse, die30 g of peptone from vegetable protein (gliadin) are dissolved in water and mixed with 15 g of iron filings cooked for a long time with the introduction of carbonic acid. The solution is filtered and evaporated in vacuo. The residue consists of a pulverizable, slightly hygroscopic yellow-brown mass, which

in Wasser mit bräunlicher Farbe löslich ist und zweiwertiges Eisen enthält. Der Eisengehalt beträgt etwa 5 Prozent.is soluble in water with a brownish color and contains divalent iron. The iron content is about 5 percent.
Die so erhaltenen Eisenverbindungen sind in trockenem Zustande beständige Körper, welche in organischen Lösungsmitteln unlöslich sind; in Wasser lösen sie sich leicht. Die wässerige Lösung wird beim Stehen durch Oxydation gelb.The iron compounds obtained in this way are stable bodies in the dry state, which are insoluble in organic solvents; they dissolve easily in water. The aqueous solution becomes yellow by oxidation on standing.
Die Ferrosalze der Monoaminosäuren sollen für therapeutische Zwecke Verwendung finden.The ferrous salts of the monoamino acids are said to be used for therapeutic purposes.

Weitere Ausbildung des durch Patent 264390, Kl. 12 q, und dessen Zusatz 264391, Kl. 12p, geschützten Verfahrens, dadurch gekennzeichnet, daß man zwecks Darstellung von Ferroverbindungen von Monoaminosäuren bzw. von Peptonen an Stelle der Glutaminsäure bzw. ihres Anhydrids hier andere Monoaminosäuren oder Peptone mit metallischem Eisen unter Ausschluß von Luft in der Wärme behandelt.Patent claim:
Further development of the process protected by patent 264390, cl. 12 q, and its addition 264391, cl. 12p, characterized in that other monoamino acids are used instead of glutamic acid or its anhydride in order to prepare ferrous compounds of monoamino acids or peptones or peptones treated with metallic iron in the heat in the absence of air.
