 gekocht. Alsdann wird das Rührwerk stillgesetzt, der Apparat 10 Minuten stehen gelassen, das Wasser und Kresol mit ihren Extrakten abgezogen und das ganze Verfahren so oft wiederholt, bis der Gummi den gewünschten Reinheitsgrad zeigt. Der abgehobene reine Kautschuk wird durch Wasserdampf oder Natronlauge vom anhaftenden Kresol befreit und das Lösemittel durch Vakuumdestillation vom Harze getrennt, um wieder benutzt werden zu können. 



   An Stelle von   o-Kresol   kann man auch   m-und p-Kresol-Phenole   oder andere Substitutionsprodukte und Homologe des Phenols verwenden oder auch   Gemische   dieser Körper, wie sie z. B. im   Kreosotöl   des Steinkohlen-oder Buchenholzteers sich finden, aus dem die harzigen und kohlenwasserstoffhaltigen Anteile, die, wie Naphtalin, Gummilöser sind, abgeschieden sind, so dass das Öl einen rein sauren Körper darstellt, der in Natronlauge löslich ist. 



   Die genannten Lösemittel sind überdies nicht nur ihrer Billigkeit wegen, sondern auch infolge ihrer geringen   Flüchtigkeit   und ihrer niedrigen latenten Wärmen mit besonderem Vorteil zu verwenden. 



   PATENT-ANSPRÜCHE :
1. Verfahren zur Gewinnung von reinem Kautschuk aus harzhaitiger Rohware, dadurch gekennzeichnet, dass die Rohware mit Phenol, Kresol oder anderen hydroxylsubstituierten Benzolabkömmlingen oder deren Gemischen wie z. B. Kreosot zwecks Auslösung der Harze behandelt wird.

 cooked. The agitator is then stopped, the apparatus is left to stand for 10 minutes, the water and cresol with their extracts are drawn off and the whole process is repeated until the rubber shows the desired degree of purity. The removed pure rubber is freed from adhering cresol by means of steam or sodium hydroxide solution and the solvent is separated from the resin by vacuum distillation so that it can be used again.



   Instead of o-cresol, it is also possible to use m- and p-cresol phenols or other substitution products and homologues of phenol, or mixtures of these substances, such as those used, for. B. found in creosote oil of coal or beech wood tar, from which the resinous and hydrocarbon-containing components, which, like naphthalene, are rubber solvents, are deposited so that the oil is a purely acidic body that is soluble in sodium hydroxide solution.



   The solvents mentioned can be used with particular advantage not only because of their cheapness, but also because of their low volatility and their low latent heat.



   PATENT CLAIMS:
1. A process for the production of pure rubber from resin-containing raw material, characterized in that the raw material with phenol, cresol or other hydroxyl-substituted benzene derivatives or mixtures thereof such. B. Creosote is treated to release the resins.
