Verfahren zur Darstellung eines als Kautschukersatz brauchbaren Produkts.Process for preparing a product useful as a rubber substitute.
Zusatz zum Patent 250920.*)Addition to patent 250920. *)
Patentiert im Deutschen Reiche vom 26. Mai 1912 ab. Längste Dauer: 7. August 1926.Patented in the German Empire on May 26, 1912. Longest duration: August 7, 1926.
Durch das Patent 250920 ist ein Verfahren zur Darstellung einer dem Kautschuk nahestehenden Substanz geschützt, das darin besteht, daß man das von Kondakow im Journal für praktische Chemie Bd. 64, S. 109/110, beschriebene Produkt mit basischen Agenzien behandelt.Through the patent 250920 is a method for the preparation of a rubber related one Substance protected, which consists in the fact that Kondakov's in the Journal for practical chemistry vol. 64, p. 109/110, described product with basic agents treated.
Es wurde nun gefunden, daß durch Zusatz von gerbstoffartigen Körpern, wie Tannin, zu dem Kondakowschen Produkt ebenfalls ein brauchbarer Kautschukersatz hergestellt werden kann. Das sonst krümelige und sehr schnell verharzende Material wird durch Mischen mit geringen Mengen dieser Körper haltbar und technisch brauchbar. Vor der Behandlung mit basischen Agenzien hat das Verfahren den-Vorzug der Verwendung nichtgiftiger Substanzen.It has now been found that by adding tannin-like bodies, such as tannin, to A useful rubber substitute can also be made for Kondakov's product can. The otherwise crumbly and very quickly resinifying material is made by mixing with small amounts of these bodies are durable and technically usable. Before treatment with basic agents, the method has the advantage of using non-toxic substances.
100 Teile Kondakowsches Produkt werden mit 6 Teilen Tannin auf der Walze zu dünnen Fellen ausgezogen. Dieselben halten sich vorzüglich an der Luft und können als gutes Kautschukersatzmittel Verwendung finden. ·100 parts of Kondakov's product are added to the roller with 6 parts of tannin stripped of thin skins. They adhere to the air and are able to do so find use as a good substitute for rubber. ·
