PATENTAMT.PATENT OFFICE.
Das Patent 141967 betrifft ein Verfahren zur Herstellung von neutral löslichen Silberverbindungen der Gelatosen. Es wurde beobachtet, daß man solche Silberpräparate auch erhält, wenn man an Stelle des Silbernitrats andere Silberverbindungen, wie z. B. milchsaures Silber, Succinimidsilber, Silberoxyd, verwendet. Bei Verwendung von Silbersalzen, die unlöslich oder schwer löslich sind, werden diese in feiner Verteilung in die konz. erwärmte Gelatoselösung eingetragen und zur Lösung gebracht; sonst ist das Verfahren dasselbe, wie es in der Patentschrift 141967 beschrieben ist.Patent 141967 relates to a method for the production of neutrally soluble silver compounds of gelatoses. It was observed that such silver preparations are also obtained if one takes the place of silver nitrate other silver compounds, such as B. lactic acid silver, succinimide silver, silver oxide, used. When using silver salts that are insoluble or sparingly soluble, these are finely distributed in the conc. heated gelatose solution entered and brought to a solution; otherwise the procedure is the same as in patent 141967 is described.
i. 100 g Gelatose, erhalten aus Glutin durch Erhitzen mit der 50 fachen Menge Wasser, werden in 40 g Wasser gelöst und durch Zugabe von 0,9 g Natronhydrat in 3 ecm Wasser neutralisiert. In die warme Lösung werden 20 g milchsaures Silber, fein gepulvert, eingetragen und durch Rühren gelöst. Die im Vakuum eingedampfte Lösung hinterläßt eine leicht pulverisierbare Masse mit einem Silbergehalt von 9,2 Prozent.i. 100 g gelatose obtained from glutin by heating with 50 times the amount of water, are dissolved in 40 g of water and neutralized by adding 0.9 g of sodium hydrate in 3 ecm of water. In the warm 20 g of lactic acid silver, finely powdered, are added to the solution and stir solved. The solution evaporated in vacuo leaves an easily pulverizable mass with a silver content of 9.2 percent.
2. Eine Lösung von IOO g Semiglutin in 40 g Wasser wird durch 0,6 g Natronhydrat neutralisiert. In diese Lösung werden unter schwachem Erwärmen 30 g Suecinimidsilber eingetragen, die allmählich in Lösung gehen. Das isolierte Produkt bildet ein gelbweißes Pulver und hat einen Silbergehalt von 12,8 Prozent.2. A solution of 100 g of semiglutin in 40 g of water are neutralized with 0.6 g of sodium hydrate. 30 g of suecinimide silver are poured into this solution with gentle heating entered, which gradually go into solution. The isolated product forms a yellow-white powder and has a silver content of 12.8 percent.
Die Silbersalze, welche man nach den beschriebenen Beispielen erhält, besitzen die allgemeinen Eigenschaften, welche auch den in der Patentschrift 141967 beschriebenen Verbindungen zukommen.The silver salts which are obtained according to the examples described have the general ones Properties, which are also the compounds described in patent specification 141967 get.
