  Verfahren zur     HerstellunL-    von     hartL-ujiiitilftliiilielieit        Forinstfleken.       Es wurde gefunden,     dass        inan        hartguniiiii-          ähnliche    Formstücke von ausserordentlich  günstigen Eigenschaften aus     Zellulosederiva-          ten,    z. B.

   Nitrozellulose oder     Azetylzelltilose,     dadurch herstellen kann,     dass    man das     Zellti-          losederivat    in     wa89erhaltigein    Zustand ohne  Zusatz von Lösungsmitteln mit einer grösse  ren Menge     Gelatinierungsmittel,    als zum     (-xe-          latinieren    des     Zelltilosederivates    erforderlich  ist, also z.

   B.     Trichlorätlivlacetanilid,        XtliN-1-          acetanilid,        Triphenylphosphat,        Essigsätire-          glyzerinester    oder     Phtalsäuredlinethylester,     unter Zusatz einer grossen Menge von     Füll-          inaterialien,    wie     kohlensaurern    Kalk, Gips,  Schwerspat, Korkmehl, Asbestmehl, Torf  mehl     usw.,    bis zur Entfernung des Wassers  erhitzt und das erhaltene Produkt dann unter  Druck und Wärme in geeignete Formen  bringt.

   Die so' erhaltenen     Presskörper    haben  <I>sofort</I> die richtige Dimension und bewahren  dieselbe,<B>da</B> sie in keiner Weise schrumpfen  und nicht nachgetrocknet     zu    werden     brau-          ehen.       <I>Beispiel:

  </I>  Etwa 400<B>g</B> Nitrozellulose, werden mit  etwa<B>250 g</B> Wasser und 1200<B>g</B> Schwerspat  in der     Knetniasehine    etwa eine halbe Stunde       innio,        "emiselit.

Nimmehr    wird die Nasse etwa eine  weitere Stunde lang bei     gewiAinlicher    Tempe  ratur innig verknetet.

   Der Inhalt der       vorrichtung    wird     nunniehr    erhitzt und das  Kneten so     latige    fortgesetzt,     bi",    alles Wasser  verdunstet ist. Alsdann wird die     ei,haltene          Alasse        in    entsprechender Menge in Formen  gebracht und bei einer Temperatur von etwa  <B>1300</B> unter     Dmek        geforint,        die        Forni    ab  gekühlt und umgestürzt, worauf     der    fertige       Presskörper    sofort gebrauchsfertig     lierausfüllt.  



  Process for the production of hard-ujiiitilftliiilielieit forinstfleken. It has been found that inan hartguniiiii--like molded pieces of extremely favorable properties made from cellulose derivatives, e.g. B.

   Nitrocellulose or acetyl cell silose, can be produced by the fact that the cell silicate derivative in wa89erhaltigein state without the addition of solvents with a larger amount of gelatinizing agent than is required for (-xelatinizing the cell silose derivative, e.g.

   B. Trichlorätlivlacetanilid, XtliN-1- acetanilid, triphenyl phosphate, Essigsätire- glycerinester or phthalic acid linear ethyl ester, with the addition of a large amount of fillers, such as carbonate of lime, gypsum, barite, cork meal, asbestos meal, peat meal, etc., until the removal of the water heated and then brings the product obtained into suitable shapes under pressure and heat.

   The pressed bodies obtained in this way <I> immediately </I> have the correct dimensions and retain the same, <B> because </B> they do not shrink in any way and do not need to be re-dried. <I> example:

  </I> About 400 <B> g </B> nitrocellulose are mixed with about <B> 250 g </B> water and 1200 <B> g </B> barite in the kneading bowl for about half an hour, " This - # lishtino is then added as about <B> 300 g </B> of one of the common gelatinizing agents, such as -Ethylaeetanilid. Then the liquid is intimately kneaded for about another hour at a certain temperature.

   The contents of the device are now heated and kneading is continued until all the water has evaporated. The egg, held alasse is then shaped in the appropriate amount and kept at a temperature of about <B> 1300 </B> Dmek geforint, the Forni cooled down and overturned, whereupon the finished pressed body fills out immediately ready for use.
