Description
Verfahren zur Herstellung eines calcium-und goldhaltigen Produktes aus einem Gemisch von Keratinabbauprodukten.
Nach dem deutschen Patent Nr. 659484 werden Haare oder ähnliche Keratingebilde mit Säuren in der Warme hydrolysiert bis s zur nahezu vollständigen Lösung, darauf die überschüssige Säure durch Dialyse und durch Eindampfen zur Trockene entfernt. Die so gewonnenen noch hÏhermolekularen wasserlöslichen Keratinabbauprodukte werden mit Goldsalzen versetzt und die dabei entstehenden sauren Reaktionsgemisahe durch Neutralisation mit Natronlauge und Fällung mit einer organischen Flüssigkeit, wie z. B. Alkohol, in wasserlösliche Natriumgoldverbin- dungen von neutraler Reaktion übergeführt.
Gegenstand des vorliegenden Patentes ist nun ein Verfahren zur Herstellung eines calcium-und goldhaltigen Produktes aus einem Gemisch von Keratinabbauprodukten, welches dadurch gekennzeichnet ist, dass man das durch Hydrolyse von Keratinen mit Säuren bis zur nahezu vollständigen Lösung, Dialyse und Eindampfen zur Trockene gewonnene saure Gemiseh von geratinabbau- produkten in wässeriger Lösung mit einer Goldsalzlösung versetzt, darauf Calciumhydroxyd bis zur schwach alkalischen Reak tion zufügt, filtriert und das calcium-und goldhaltige Produkt durch Einrühren der wässerigen Lösung in ein organisches Lösungsmittel ausfallt. Das entstandene calcium-und goldhaltige Produkt, welches das Anion des verwendeten Goldsalzes nicht enthält, ist wasserlöslich und gleich so rein,
dass es ohne weiteres als Heilmittel zum Beispiel far Injektionen benutzt werden kann. Dieses Produkt ist für die Gewebe gut verträglich.
Man hat bereits vorgeschlagen, zunächst Goldkeratinate in Substanz direkt aus einem durch Hydrolyse von Haaren mit Salzsäure gewonnenen Hydrolysa herzustellen, dieses saure wasserunlösliche Produkt in Wasser aufzuschwemmen und mit Calciumhydroxyd so lange zu schütteln, bis eine weitere Lo sung der Goldverbindung nicht mehr erfolgt, worauf die alkalisch reagierende Flüssigkeit von ungelösten Anteilen abfiltriert und das Filtrat in Alkohol eingegossen wird.
Das so gewonnene Produkt wird noch zweimal in Wasser gelöst und mit Alkohol gef llt, um es zu rein. en., l2it dem so erhaltenen Produkt ils liegenden V ifs-I
Vor dem älteren;V.erahrnhatdasvor- liegende, das von einem durch Dialyse und Eindampfen vorgereinigten Keratinabbau- produkt ausgeht, den Vorteil viel grösserer Einfachheit und der Vermeidung von Verlusten an Goldverbindungen.
Beispiel :
5 g Keratinhydrolysat. das durch Behandlung von Haaren mit der vierfachen Menge 25Siger Salzs ure auf dem Wasserbade, bis nur noch ein kleiner Rest ungelöst blieb, anschliessende Dialyse und Eindamp- fen bis zur Trockene gewonnen wurde, werden in 25 cm3 Wasser gelöst. In die Lösung werden 1,2 g Goldtrichlorid, in 6 cm3 Wasser gelöst, anteilsweise eingerührt. Hierauf wird Calciumhydroxyd bis zur schwach alkali schen Reaktion zugesetzt. Nach einigem Stehen wird filtriert und die Lösung in die me, hrfache Menge Alkohol eingerührt, wobei ein helles Produkt ausfällt, das abgenutscht, mit Alkohol ausgewaschen und im Vakuum getrocknet wird.
Das gelbliche Produkt ist in Wasser leicht löslich.
Process for the production of a calcium- and gold-containing product from a mixture of keratin breakdown products.
According to German patent no. 659484, hair or similar keratin structures are hydrolyzed with acids in the warm until they are almost completely dissolved, then the excess acid is removed by dialysis and by evaporation to dryness. The even higher molecular water-soluble keratin degradation products obtained in this way are mixed with gold salts and the acidic reaction mixtures formed by neutralization with sodium hydroxide solution and precipitation with an organic liquid, such as. B. alcohol, converted into water-soluble sodium gold compounds of neutral reaction.
The present patent now relates to a process for the production of a calcium- and gold-containing product from a mixture of keratin degradation products, which is characterized in that the acidic vegetable obtained by hydrolysis of keratins with acids until almost complete dissolution, dialysis and evaporation to dryness is used A gold salt solution is added to geratin degradation products in aqueous solution, calcium hydroxide is then added until it has a weakly alkaline reaction, filtered and the calcium and gold-containing product is precipitated by stirring the aqueous solution into an organic solvent. The resulting calcium- and gold-containing product, which does not contain the anion of the gold salt used, is water-soluble and so pure,
that it can easily be used as a remedy, for example for injections. This product is well tolerated by the tissues.
It has already been proposed to first prepare gold keratinates in substance directly from a hydrolysis obtained by hydrolysis of hair with hydrochloric acid, to suspend this acidic, water-insoluble product in water and to shake it with calcium hydroxide until the gold compound no longer dissolves, whereupon the alkaline liquid is filtered off from undissolved components and the filtrate is poured into alcohol.
The product obtained in this way is dissolved twice more in water and filled with alcohol in order to purify it. en., l2 with the product obtained in this way, V ifs-I
Before the older one, V., the present one, which proceeds from a keratin degradation product pre-purified by dialysis and evaporation, has the advantage of much greater simplicity and the avoidance of losses of gold compounds.
Example:
5 g keratin hydrolyzate. which was obtained by treating hair with four times the amount of 25% hydrochloric acid on the water bath until only a small residue remained undissolved, followed by dialysis and evaporation to dryness, are dissolved in 25 cm3 of water. 1.2 g of gold trichloride, dissolved in 6 cm3 of water, are partially stirred into the solution. Calcium hydroxide is then added until the reaction is weakly alkaline. After standing for a while, it is filtered and the solution is stirred into the multiple amount of alcohol, a light-colored product precipitating which is suction filtered, washed out with alcohol and dried in vacuo.
The yellowish product is easily soluble in water.
