Description
Unter geklärten Farbholzextracten sind solche. Extracte zu verstehen, welche frei von Pflanzenschleimstoffen, Harzen, Gummi, Pectinen, Albuminen sind; denn wesentlich die Harze, Pectine und Albumine trüben die Färbeflotten, und befördern die Gährung derselben, setzen Schlamm ab, beeinflussen die Reinheit der ■Färbekraft und Farbenschöhheit auf der Faser und die Dauerhaftigkeit des. Extractes. ■:Clarified colored wood extracts include such. To understand extracts which are free from plant mucilage, resins, gum, pectins, albumins; because essentially the resins, pectins and albumins cloud the dye liquors, and promote fermentation of the same, settle sludge, affect the purity of the ■ Dye strength and color beauty on the fiber and the durability of the extract. ■:
Die Färbekraft, Echtheit und Schönheit des .betreifenden Farbstoffes wird — unter Abscheidung obengenannter Stoffe ^- noch be-; sonders erhöht durch eine gleichzeitige Oxydation, d. h. die Ucberfuhrung. des im Holze vorhandenen Farbstoffes in die höhere Oxydationsstufe, z. B. Ucberfuhrung des Hamatoxylins in Hiimatc'in. :The coloring power, authenticity and beauty of the relevant dye is - with the separation of the above-mentioned substances - still under; but increased by a simultaneous oxidation, i. H. the transfer. of the wood existing dye in the higher oxidation level, z. B. Conversion of hematoxylin in Hiimatc'in. :
Man extrahirt das geraspelte, schwach fermentirleFarbholz in bekannter Weise '/.,Stunde lang mit kochendem Wasser unter einem Drucke von 2 γ, Atmosphären nach dem Diffusionsverfahren. Hierauf fügt man zu iooool Brühe, welche ungefähr eine Dichtigkeit von 30B. besitzt, 200 g doppeltchromsaures Kalium in wenig Wasser gelöst, sowie 100 g Schwefelsäure hinzu,, sorgt durch ein Rührwerk im' Bassin für innige Mischung, erhalt die Temperatur vermittelst Dampfzuführung auf ca. 60° C. und elektrolysirt. Die beiden Elektroden be-. stehen am besten aus Platindrahtgeflechten, die in einem Holzrahmen festgespannt sind. Die. Gröfse, der Elektrodenoberfläche richtet sich nach dem Bassingehalte; Am praktischsten sind Bassins von 12 000 1 Inhalt, welche also 3 m ! breit, 4 m lang und im hoch sind.The rasped, weakly fermentable colored wood is extracted in a known manner for 1 hour with boiling water under a pressure of 2 γ atmospheres by the diffusion process. Then is added to iooool broth containing approximately has a density of 3 0 B. dissolved 200 g bichromate potassium in a little water, and 100 g of sulfuric acid are added ,, ensures by an agitator in the 'pool for intimate mixture, maintaining the temperature by means of steam supply to about 60 ° C. and electrolyzed. The two electrodes are loaded. are best made of platinum wire mesh, which is clamped in a wooden frame. The. The size of the electrode surface depends on the basin content; The most practical are pools with a capacity of 12,000 liters, which is 3 m ! wide, 4 m long and im high.
Die Elektroden stehen sich alsdann etwa 4 m entfernt, an den Breitseiten der Bassinwandungeiv befestigt, einander gegenüber. Man läfst nun.'. einen Strom von 12 Ampere und 60 Volt Y1 Stunde lang auf die Flotte einwirken. Bei dieser Behandlung scheiden sich die vorhin erwähnten Stoffe gröfstentheils als· Schlamm aus; man neutralisirt durch Strontium- oder Bariumcarbonat, leitet die Gesammtflotte über^ einen Oberflächenkühlapparat, 'filtrirt durch eine . Filterpresse und dampft das Filtrat im Vacuum zu Extract von gewünschter Stärke ein.The electrodes are then about 4 m apart, attached to the broad sides of the basin wall, opposite one another. You are now running. '. Apply a current of 12 amps and 60 volts Y to the liquor for 1 hour. In this treatment the substances mentioned above are for the most part separated out as sludge; if neutralized by strontium or barium carbonate, the total liquor is passed over a surface cooling apparatus, filtered through a. Filter press and evaporate the filtrate in a vacuum to extract the desired strength.
Vorstehendes Verfahren unterscheidet sich wesentlich von dem durch die Patentschrift Nr. 69055 bekannt gewordenen durch eine gleichzeitige Oxydation der Flotte neben der,: Elektrolyse, d. h. durch die Ueberführung des im Holze vorhandenen Farbstoffes in die höhere Oxydationsstufe. . 'The above procedure is different substantially different from that provided by the patent specification No. 69055 made famous by a simultaneous oxidation of the liquor in addition to the,: Electrolysis, d. H. by converting the dye present in the wood into the higher one Oxidation level. . '
Die Oxydation wird bewirkt theils durch die Fermentation des Rohmaterials, theils durch die Wirkung des doppeltchromsauren Kaliums in.. .Gemeinschaft mit Schwefelsäure. Beendigt wird; die Oxydation durch die Elektrolyse. ; :'The oxidation is brought about partly by the fermentation of the raw material, partly by the action of the double-chromic potassium in ... together with sulfuric acid. Is terminated; the oxidation by electrolysis. ; : '
