Description
Verfahren zur Darstellung einer komplexen Silherverbindung eines Gemisches von a-Aminosüuren. Komplexe Silberverbindungen von a- Aininosäuren sind noch nicht bekannt. Bei Zusatz von Ammoniak und Aminen, z. B.
von Methylamin, Äthylamin oder Äthylen- damin, sowie von Cyaniden, Thiosulfa.t,en, Rhodaniden zu organischen und anorgani- sehen Silbersalzen entstehen bekanntlich komplexe Silbersalze, welche das Silber nicht oder nur zum geringsten Teil in der Form des elektrisch dissozierten einwertigen Silberkations besitzen.
Die Ammoniak- und Aminverbindungen enthalten nach den Un tersuchungen von Bodländer (Berichte der Deutschen Chemischen Gesellschaft 36, 1903, S. 2878<B>)</B>, Bodländer und Fittig (Zeitschrift für physiologische Chemie 39, 1902, S. 605), sowie von Euler (Berichte der Deutschen Chemischen Gesellschaft 36, 1903, S. 1854) das komplexe Kation (Ag [Am]_)', wo Am NH3, <B>CH,</B> NH, usw. bedeutet.
Die Cyanid- doppelsalze weisen das komplexe Anion (Ag [CN]2)', die Rhodaniddoppelsalze das Anion (Ag [SCN]2)', die Thiosulfatdo@ppel- salze das Anion (Ag [S,0.,11)"' und (Ag [S20313)'/"' auf.
Gegenstand der vorliegenden Erfindung ist ein verfahren zur Darstellung einer neuen komplexen Silberverbindung eines Gemisches von a-Aminosä Uren, welches dar auf beruht, dass man auf Glykokollsilber einen tberschuss eines Gemisches von a Aminosäuren, wie es durch Totalhydrolyse von Eiweisskörpern gewonnen wird, zur Ein wirkung bringt.
Die entstehende komplexe Silberverbin- diing ist sehr lichtempfindlich. Sie löst. sich in Wasser auch in der Kälte sehr leicht. Die Lösung reagiert auf Lackmus alkalisch; mit. Soda und Natronlauge bleibt sie klar.
Beispiel: 7. Teil Glykokollsilber wird mit 4 Teilen eines Gemisches von a-Aminosäuren, wie es durch Hydrolyse von Seide mit Schwefel säure gewonnen wird, fein verrieben. Die wässerige Lösung des entstandenen Salzes enthält das Silber in komplexer Bindung.
Process for the preparation of a complex silver compound of a mixture of α-amino acids. Complex silver compounds of α-amino acids are not yet known. With the addition of ammonia and amines, e.g. B.
From methylamine, ethylamine or ethylene-damin, as well as from cyanides, thiosulfa.t, en, rhodanides to organic and inorganic silver salts, complex silver salts are known to form, which do not have the silver or only to a small extent in the form of the electrically dissociated monovalent silver cation .
The ammonia and amine compounds contain, according to the investigations by Bodländer (reports of the German Chemical Society 36, 1903, p. 2878 <B>) </B>, Bodländer and Fittig (magazine for physiological chemistry 39, 1902, p. 605) , as well as from Euler (reports of the German Chemical Society 36, 1903, p. 1854) the complex cation (Ag [Am] _) ', where Am means NH3, <B> CH, </B> NH, etc.
The cyanide double salts have the complex anion (Ag [CN] 2) ', the rhodanide double salts the anion (Ag [SCN] 2)', the thiosulphate do @ ppel salts the anion (Ag [S, 0., 11) "' and (Ag [S20313) '/ "'.
The present invention relates to a process for the preparation of a new complex silver compound of a mixture of α-amino acids, which is based on the fact that an excess of a mixture of α-amino acids, such as is obtained by total hydrolysis of protein bodies, is used on glycocollsilver brings.
The resulting complex silver compound is very sensitive to light. She solves. very easily in water even in the cold. The solution has an alkaline reaction to litmus; With. Soda and caustic soda stay clear.
Example: 7th part of glycocollsilver is finely ground with 4 parts of a mixture of a-amino acids, as obtained by hydrolysis of silk with sulfuric acid. The aqueous solution of the resulting salt contains the silver in a complex bond.
