PATENTAMT.PATENT OFFICE.
Den Gegenstand des vorliegenden Patentes bildet eine Neuerung in dem Verfahren
zur Herstellung horn- oder ebonitartiger Massen aus Hefe und Formaldehyd.
Es wurde gefunden, daß es für die Herstellung hornartiger Massen, die durch Pressung
von mit Formaldehyd behandelter Hefe, mit oder ohne Zusatz anderer Substanzen, gewonnen werden, wichtig ist, daß vor demThe subject of the present patent is an innovation in the process for the production of horn-like or ebonite-like masses from yeast and formaldehyde.
It has been found that it is important for the production of horn-like masses obtained by pressing yeast treated with formaldehyde, with or without the addition of other substances, that before
ίο Pressen der Massen die Materialien möglichst weitgehend entwässert werden. Ein Abpressen der Hefe führt insofern nicht zum Ziel, als es praktisch unmöglich ist, die Hefe durch bloßes Pressen auf den genügenden Grad der Trockenheit zu bringen, zumal die Hefe, wie bekannt, in den Filterpressen durch die Filtertücher hindurchgeht.ίο pressing the masses the materials as possible are largely drained. Squeezing the yeast does not achieve the goal, when it is practically impossible to remove the yeast by merely pressing it to a sufficient degree Bring dryness, especially since the yeast, as is known, in the filter presses through the filter cloths passes through.
Es wurde nun gefunden, daß wider Erwarten ein für die Pressung außerordentlich brauchbares Material gewonnen wird, wenn die mit Formalin behandelte Hefe direkt getrocknet wird. Das so gewonnene trockne Produkt läßt sich nach entsprechender Zerkleinerung leicht und billig pressen und ergibt, wenn die Temperatur bei der Pressung gegen 100 ° gesteigert wird, Massen, die in ihrem äußeren Aussehen dem Ebonit gleichen und auch ähnliche physikalische Eigenschaften haben wie dieser. Dieses Resultat ist nicht zu erreichen, wenn man versucht, abgepreßte Hefe mit Formaldehyd zu behandeln und sie mit dem ihr noch anhaftenden Wasser der Pressung zu unterwerfen. Es entstehen dann zwar auch Preßkörper, die aber nach dem Aufhören des Preßdruckes und bei Beginn der weiteren Trocknung rissig werden und die Form verlieren.It has now been found that, contrary to expectations, an extraordinary one for the pressing Useful material is obtained when the formalin treated yeast is dried directly will. The dry product obtained in this way can be broken down appropriately easy and cheap pressing and yields if the temperature at the pressing is increased towards 100 °, masses that are in their external appearance resembles that of ebonite and also has similar physical properties have like this. This result cannot be achieved if one tries to squeeze Treat yeast with formaldehyde and remove it with the water that is still adhering to it Submit pressing. There are then also pressed bodies, but after the Stop the pressure and at the beginning of the further drying cracks and lose shape.
In den Fällen, in denen man andere Eiweißkörper mitverarbeitet, kann man die Entwässerung der Hefe auch derartig durchführen, daß man die Eiweißstoffe mit der so-' weit wie möglich durch Filtration entwässerten Hefe mischt und in dem Gemisch die Eiweißstoffe zur Fällung oder zur Koagulation bringt. So werden Materialien zum Pressen aus Gemischen von Hefe und Blutalbumin beispielsweise derartig hergestellt, daß das Blutalbumin in der Kälte in der dem Hefebrei anhaftenden wäßrigen Flüssigkeit aufgelöst wird und das Gemisch darauf aufgekocht wird. Es bildet sich als Koagulat ein inniges Gemisch von Hefe und geronnenem Albumin, das sich sehr gut trocknen und für die spätere Pressung vorzerkleinern läßt.In those cases where other protein bodies are also processed, you can use the Carry out dehydration of the yeast in such a way that the proteins with the so- ' As far as possible by filtration dehydrated yeast mixes and in the mixture the Brings protein substances to precipitation or coagulation. This is how materials are made for pressing made from mixtures of yeast and blood albumin, for example, in such a way that the Blood albumin dissolved in the cold in the aqueous liquid adhering to the yeast pulp and the mixture is then boiled. An intimate coagulate forms Mixture of yeast and coagulated albumin, which can be dried very well and used for later Pressing can be pre-shredded.
Derartig vorgetrocknete Materialien lassen sich, wie oben bereits erwähnt, unter Preßdruck sehr gut zu festen Körpern vereinigen. Nimmt man die Pressung indessen bei niederen Temperaturen vor, so sind die entstandenen Preßlinge nicht wasserfest, sondern werden, in Wasser eingelegt, durch Aufnahme von Feuchtigkeit zerstört. Steigert man hingegen die Temperatur über 60 °, so verändert sich der Preßling, indem seine vorher bräunlichgraue Farbe in Grauschwarz übergeht und die bis dahin mehr oder minder körnigeSuch predried materials can be, as already mentioned above, under pressure combine very well into solid bodies. If one takes the pressure, however, at lower ones Temperatures before, the resulting compacts are not waterproof, but are soaked in water, destroyed by the absorption of moisture. On the other hand, if you increase if the temperature is above 60 °, the pressed part changes by removing its previously brownish-gray Color changes to gray-black and the more or less grainy one up to that point

15 g Blutalbumin werden in einer entsprechenden Menge von Wasser von 40 ° gelöst und die Lösung mit 1 kg Hefebrei von etwa 15 Prozent Trockensubstanz gemischt. Das Gemisch wird dann bis zum Kochen erhitzt und das entstandene Gemenge von geronnenem Albumin und niedergerissenen Hefebestandteilen von der Flüssigkeit getrennt. Der entstandene Brei wird mit 150 g käuflichem, prozentigem Formaldehyd vermengt und dann getrocknet. Nach geeigneter gleichmäßiger Zerkleinerung wird das erhaltene Material bei Temperaturen von etwa 90° und einem Druck von 250 bis 300 Atm. in Formen gepreßt. 15 g of blood albumin are dissolved in a corresponding amount of water at 40 ° and the solution mixed with 1 kg of yeast pulp of about 15 percent dry matter. That Mixture is then heated to a boil and the resulting mixture of coagulated Albumin and broken down yeast components are separated from the liquid. Of the The resulting pulp is mixed with 150 g of commercially available percent formaldehyde and then dried. After suitable, uniform comminution, the material obtained is at temperatures of about 90 ° and a pressure of 250 to 300 atm. pressed into molds.
