Zusatz zum Patent 265221.Addendum to patent 265221.
Patentiert im Deutschen Reiche vom 25. Dezember 1912 ab. Längste Dauer: 15. November 1927.Patented in the German Empire on December 25, 1912. Longest duration: November 15, 1927.
Durch das Hauptpatent 265221 ist ein Verfahren zur Beschleunigung der Vulkanisation von natürlichen oder künstlichen Kautschukarten beschrieben, welches darin besteht, daß man der zu vulkanisierenden Masse Piperidin oder seine Homologen zusetzt.The main patent 265221 provides a method for accelerating vulcanization of natural or synthetic rubbers, which consists in that one adds piperidine or its homologues to the mass to be vulcanized.
Es wurde nun gefunden, daß — wie Piperidin und seine Homologen — auch die Derivate des Piperidine und seiner Homologen mit dem gleichen Erfolge verwendet werden können. Die Benutzung dieser Derivate hat den Vorteil, daß es sich bei ihnen meist um geruchlose oder nur schwach riechende Verbindungen handelt, die in vielen Fällen sich auch noch vor dem flüssigen Piperidin und seinen Homologen durch feste oder kristallinische Form auszeichnen.It has now been found that - like piperidine and its homologues - also the derivatives des piperidine and its homologues can be used with equal success can. The use of these derivatives has the advantage that they are mostly odorless or only weakly smelling compounds are, in many cases even before the liquid piperidine and its homologues by solid or crystalline ones Distinguish shape.

20th
100 Teile Parakautschuk werden mit 10 Teilen Schwefel und 1 Teil des bei 172 ° schmelzenden piperidyldithiocarbamidsauren Piperidins bei 135 bis 145 ° (31Z2 Atm.) 15 Minuten vulkanisiert; man erhält so einen gut ausvulkanisierten Weichgummi. Vulkanisiert.man nur bei 120 bis 125 ° (2V4 Atm.) während ι Stunde, so erhält man ebenfalls ein gutes Produkt.100 parts of para rubber are vulcanized with 10 parts of sulfur and 1 part of piperidyldithiocarbamic acid piperidine, which melts at 172 °, at 135 ° to 145 ° (3 1 Z 2 atmospheres) for 15 minutes; a well-vulcanized soft rubber is obtained in this way. Vulkanisiert.man only at 120 to 125 ° (2V4 atm.) For ι hour, you also get a good product.
Ersetzt man den Parakautschuk durch Plantagenkautschuk oder durch künstlichen Isoprenkautschuk, so erhält man ein ähnliches Resultat. If you replace the para rubber with plantation rubber or synthetic isoprene rubber, a similar result is obtained.
100 Teile β-γ-Dimethylbutadienkautschuk (Patent 250335) werden mit 50 Teilen Schwefel und ι Teil Monopiperidylharnstoff der Formel:100 parts of β-γ- dimethylbutadiene rubber (patent 250335) are mixed with 50 parts of sulfur and ι part of monopiperidylurea of the formula:
NH2—CO—N(NH 2 —CO — N (
— CH 2 - CH 2

)CH2 ) CH 2
ch9—ch/ch 9 - ch /
bei etwa 155° (5 bis 6 Atm.) vulkanisiert; man erzielt so einen vorzüglichen Hartgummi. Verwendet man statt 50 nur 10 Teile Schwefel und vulkanisiert 1 Stunde bei 120 bis 125 ° (21Z4 Atm.), so erhält man ein gutes weichgummiähnliches Vulkanisat.vulcanized at about 155 ° (5 to 6 atm.); you get an excellent hard rubber. If only 10 parts of sulfur are used instead of 50 and vulcanized for 1 hour at 120 to 125 ° (2 1 Z 4 atm.), A good, soft rubber-like vulcanizate is obtained.
An Stelle der in den Beispielen genannten Kautschukarten können auch andere Kautschukarten, wie z. B. Plantagenkautschuk, normaler oder Natriumbutadienkautschuk, Na-Instead of the types of rubber mentioned in the examples, other types of rubber, such as B. Plantation rubber, normal or sodium butadiene rubber, Na-

Verwendung finden; ebenso können die in den Beispielen genannten Piperidinverbindungen durch n-Thiopiperidin (Michaelis, Ber.28,1013) oder durch Benzaldipiperyl (Journal für praktische Chemie [2], Band 36, Seite 130) oder andere feste oder flüssige Derivate des Piperidins und seiner Homologen ersetzt werden.trium isoprene rubber, etc. find use; as can those in the examples named piperidine compounds by n-thiopiperidine (Michaelis, Ber.28,1013) or by Benzaldipiperyl (Journal for Practical Chemistry [2], Volume 36, Page 130) or other solid or liquid derivatives of piperidine and its homologues are replaced.
Claims (1)
Abänderung des durch Patent 265221 geschützten Verfahrens zur Beschleunigung der Vulkanisation von natürlichen oder künstlichen Kautschukarten, darin bestehend, daß man der zu vulkanisierenden Masse an. Stelle von Piperidin oder seiner Homologen Derivate dieser Basen zusetzt.Patent claim:
Modification of the process, protected by patent 265221, for accelerating the vulcanization of natural or synthetic rubbers, consisting in the fact that the mass to be vulcanized is applied. Place of piperidine or its homologues derivatives of these bases added.
