Zusatz zum Patent 309264.Addendum to patent 309264. Patentiert im Deutschen Reiche vom 9. November 1918 ab. Längste Dauer: 10. Juni 1933.Patented in the German Empire on November 9, 1918. Longest duration: June 10, 1933. In dem Hauptpatent 309264 ist ein Beizverfahren für schmiedbares Eisen und Stahl geschützt, welches im Zusatz von Rohanthrazen, Sulfitablauge, Rückständen der Naphthalingewinnung u. dgl. zur Beizflüssigkeit besteht. Nach dem vorliegenden Verfahren setzt man die angegebenen Stoffe nicht in Substanz dem Beizbade zu, sondern verwendet geeignete Extrakte dieser Stoffe. Es hat sich gezeigt, daß nicht die Hauptbestandteile dieser Stoffe, wie z. B. Anthrazen, Naphthalin, Phenol usw., eine besonders günstige Wirkung ausüben, sondern Beimengungen, deren chemische Konstitution bisher nicht aufgeklärt werden konnte, die aber fast ständige Begleiter der erwähnten Substanz sind. Man kann die fraglichen Stoffe durch anorganische Säuren, neutrale oder saure Salze, organische Lösungsmittel, wie Kohlenwasserstoffe (Petroleum, Teeröle), extrahieren. Zweckmäßig extrahiert man die betreffenden Stoffe mit drei bis vier Teilen Schwefelsäure verschiedener Grädigkeit, Salzsäure und anderen geeigneten Extraktionsmitteln und setzt dem Beizbade je nach Stärke ι bis 10 Prozent dieses Extraktes zu. Auch die bei der Reinigung von Erdölen, Braunkohlenteerölen, Steinkohlenteerölen, Paraffin u. dgl. mit Schwefelsäure entstehenden Abfall- j säuren oder Säureharze sowie Destillations- j rückstände organischer Verbindungen jeder j Art, insbesondere Rückstände, bei denen eine j pyrogene Zersetzung stattgefunden hat, können verwendet werden. Die Extrakte können auch neben, den Stoffen in Substanz angewendet werden.In the main patent 309264 is a pickling process for forgeable iron and steel protected, which in the addition of raw anthracene, sulphite waste liquor, residues of naphthalene recovery and the like to the pickling liquid. According to the present process, the specified substances are not used in substance Pickling bath too, but uses suitable extracts of these substances. It has shown, that not the main components of these substances, such as. B. anthracene, naphthalene, phenol, etc., exert a particularly beneficial effect, but admixtures, their chemical constitution so far could not be cleared up, but the almost constant companion of the mentioned Are substance. One can neutralize the substances in question through inorganic acids or acid salts, organic solvents such as hydrocarbons (petroleum, tar oils), extract. The substances in question are expediently extracted with three to four parts Sulfuric acid of various degrees, hydrochloric acid and other suitable extractants and sets the pickling bath depending on the strength ι to 10 percent of this extract too. Also those involved in the purification of crude oils, lignite tar oils, Coal tar oils, paraffin and the like, waste acids or acid resins formed with sulfuric acid, as well as distillation j residues of organic compounds of all j types, in particular residues where a j Pyrogenic decomposition has occurred can be used. The extracts can can also be used in addition to the substances in substance. Der Vorteil dieses abgeänderte^ Verfahrens beruht darauf, daß die extrahierte Substanz ohne nennenswerten Verlust ihrem bisherigen Zweck zugeführt werden kann und das- Beizbad sowie das gebeizte Material nicht durch die zugesetzten Substanzen verunreinigt werden. In gleicher Weise wie. zum Beizen kann das Präparat auch zur Entfernung von Rost, Zink, Zinn und anderen das Eisen überziehende Schichten Verwendung finden.The advantage of this modified ^ procedure is based on the fact that the extracted substance without significant loss of its previous Purpose can be supplied and the pickling bath and the pickled material not through the added substances are contaminated. In the same way as. can be used for pickling Preparation also for removing rust, zinc, tin and other iron-plating agents Layers are used. Das Verfahren des Hauptpatentes und das vorliegende Verfahren ist nicht auf schmiedbares Eisen oder Stahl beschränkt, sondern kann auch für andere Eisensorten, wie Gußeisen, Eisenlegierungen (Nickel-, Chrom-, Wolframusw. Stahl u. dgl.), angewendet werden.The process of the main patent and the present process is not for forgeable Iron or steel, but can also be used for other types of iron, such as cast iron, Iron alloys (nickel, chromium, tungsten, etc. steel and the like) can be used.
