 vom Kautschuk abgetrennten Flüssigkeit genügt ferner, die Schwefelmenge wieder zu gewinnen und gleichzeitig die verwandelte Lösung zu regenerieren. 



   Da die zerkleinerten Kautschukstücke unter Verwendung einer wässerigen Lösung oder eines   Breies,   gebildet von Sulfite und Wasser, behandelt wurden, so verbleibt nach dem Auswaschen derselben nichts von dem zum Entvulcanisieren benützten Stoffe darin : man gewinnt ein reines, nach dem Trocknen sofort wieder   verwendungsfähiges   Material.

 EMI2.1
 Liquid separated from the rubber is also sufficient to recover the amount of sulfur and at the same time regenerate the converted solution.



   Since the crushed pieces of rubber were treated with the use of an aqueous solution or a paste formed from sulphites and water, nothing of the substances used for devulcanizing remains in them after they have been washed out: a pure material is obtained that can be used again immediately after drying.
