Verfahren zur Gewinnung von Atbumintosungen.
Versuche mit dem im Patente Nr. 45591 beschriebenen Verfahren haben ergeben, dass dies einer erheblich erweiterten Ausgestaltung und Anwendung fähig ist.
Es hat sich herausgestellt, dass Ameisensäure Albumin leicht zu lösen vermag. Nach Verdunstenlassen der Säure kann es wiedergewonnen werden, wobei dann Häutchen entstehen, die wasserunlöslich sind. Man kann derart auch Kunstseide unmittelbar aus Eiweiss herstellen, ohne Formaldehyd benutzen. zu müssen. Ebenso lassen sich auch Films, Form- stücko und dergleichen in Gestalt dünner Platten usw. auf die beschriebene Weise leicht erzeugen.
Hierbei fährt man am besten so, dass man die Lösung in der Kälte vornimmt, da ein längeres Erhitzen schädlich wirkt und hierbei tiefer gehende Spaltungen nur schwer zu vermeiden sind. Ebenso darf man die Säure auch nicht zu lange einwirken lassen, sonst zeigen die nach dem Verjagen der Säure erhaltenen Rückstände Neigung zur Sprodigkcit.
EMI1.1
Glycerin, Kampher, Schellack, Traganth, Agar-Agar, Gelatine, oder auch Tannin gegeben.
Ausführungsbeispiel.
Das wasserlösliche Albumin wird bei gewöhnlicher Temperatur innerhalb weniger Stunden im Verhältnis von 1 : 10 in Ameisensäure (90--990/0) gelöst. Die Ameisensäure kann abgerundet werden. Der Rückstand ist wasserunlöslich, hochglänzend und durchsichtig.
Versetzt man eine Lösung von Albumin in Ameisensäure mit einer Lösung von Tannin in Ameisensäure, so entsteht kein Niederschlag. Beim Verdunsten gibt die Mischung einen glänzenden, durchsichtigen, je nach dem Gehalt an Tannin mehr oder weniger gegen Wassnr widerstandsfähigen Rückstand. An Stelle des Tannins können auch andere, hiezu geeignete Körper hinzugefügt werden, insbesondere die bereits erwähnten Stoffe, Glycerin, Kampher, Schellack, Traganth, Agar-Agar oder Gelatine.
PATENT-ANSPRÜCHE :
1. Ausgestaltung des Verfahrens nach Patent Nr. 45591, dadurch gekennzeichnet, dass zwecks Erzielung einer Albuminlösung Albumin mit Ameisensäure behandelt wird.

Process for obtaining atbumin cans.
Tests with the method described in patent no. 45591 have shown that this is capable of a considerably expanded design and application.
It has been found that formic acid can easily dissolve albumin. After the acid has been allowed to evaporate, it can be recovered, which then results in membranes that are insoluble in water. You can also make rayon directly from egg white without using formaldehyde. to have to. Likewise, films, molded pieces and the like in the form of thin plates etc. can also easily be produced in the manner described.
The best way to do this is to do the solution in the cold, as prolonged heating is harmful and deeper splits are difficult to avoid. Likewise, the acid must not be left to act for too long, otherwise the residues obtained after the acid has been driven off show a tendency to become brittle.
EMI1.1
Glycerin, camphor, shellac, tragacanth, agar-agar, gelatine or even tannin are given.
Embodiment.
The water-soluble albumin is dissolved in formic acid (90-990 / 0) in a ratio of 1:10 within a few hours at normal temperature. The formic acid can be rounded off. The residue is insoluble in water, glossy and transparent.
If a solution of albumin in formic acid is mixed with a solution of tannin in formic acid, no precipitate is formed. When it evaporates, the mixture gives a shiny, transparent residue, more or less resistant to water, depending on the tannin content. Instead of the tannin, other substances suitable for this can also be added, in particular the substances already mentioned, glycerine, camphor, shellac, tragacanth, agar-agar or gelatine.
PATENT CLAIMS:
1. Development of the method according to patent no. 45591, characterized in that albumin is treated with formic acid in order to obtain an albumin solution.
