Description
Verfahren zur Herstellung chlorreicher Produkte aus Sulfitzellstoffablaugen oder daraus hergestellten Celluloseextrakten. Sulfitzellstoffablauge bzw. daraus hergestellte Produkte werden seit längerer Zeit schon zu gerbereitechnischen Zwecken verwendet. Die zur Verwendung gelangenden Extrakte sollen technisch frei von Eisen und Kalk sein und keine schädlichen freien Säuren mehr enthalten. Die Celluloseextrakte dienen in der Gerberei zum Angerben, weil sie mit großer Leichtigkeit in das Leder einziehen und ein schnelleres Durchbieißen der Gerb Stoffe ermöglichen, ferner als Mischprodukt im Farbengang und im Faß, zum Nachgerben, als Füllmittel und als Lösungsmittel für schwerlösliche vegetabilische Gerbextrakte, die dadurch leicht in Lösung gehen. In allen Fällen also dienen die C elluloseextrakte nur als Zusatz zu anderen Gerbstoffen, für sich allein als Gerbmittel können sie nicht verwendet werden, weil sie nur ein blechernes, unbrauchbares Leder liefern.Process for the production of chlorine-rich products from sulphite pulp waste liquors or cellulose extracts made therefrom. Sulphite pulp waste liquor or from it Manufactured products have been used for tanning purposes for a long time used. The extracts used should be technically free of iron and lime and no longer contain harmful free acids. The cellulose extracts are used in the tannery for tanning because they get into the leather with great ease pull in and enable the tanning fabrics to bite through faster, furthermore than Mixed product in the color range and in the barrel, for retanning, as a filler and as a solvent for vegetable tanning extracts that are difficult to dissolve and thus easily dissolve. In all cases, the cellulose extracts only serve as an additive to other tanning agents, They cannot be used on their own as a tanning agent because they are only one Delivering tinny, unusable leather.
Es wurde nun gefunden, daß man durch Behandeln der Sulfitcelluloseablauge oder der daraus hergestellten Extrakte mit freiem Chlor zu gechlorten Produkten gelangt, welche hervorragende Berberische Eigenschaften besitzen, so daß sie nicht nur wie diese als Zusatz, sondern auch für sich allein zum Gerben verwendet werden können, wvobei sie ein schönes, braunes, vollgriffiges Leder ergeben, welches durchaus dem aus pflanzlichen Gerbstoffen erhaltenen Leder gleicht. Die im »Chemischen Zentralblatt« 19o6, Seite 1854, beschriebene, aus Sulfitzellstoffablauge mit Chlorkalk und Salzsäure erhaltene Verbindung von der Formel C26 H29 Cl S0,2 ist nicht identisch mit dem nach vorliegender Erfindung erhaltenen Produkt. Während jene Verbindung nur 5,8 Prozent Chlor aufweist und in Alkohol fast unlöslich ist, enthält das gemäß der vorliegenden Erfindung hergestellte Produkt 36 Prozent Chlor und löst sich mit größter Leichtigkeit und vollkommen in Alkohol.It has now been found that by treating the sulphite cellulose liquor or the extracts made from it with free chlorine to produce chlorinated products which have excellent Berber properties, so they do not can only be used as an additive like this, but also on its own for tanning can, whereby they result in a beautiful, brown, full-grip leather, which definitely is similar to leather obtained from vegetable tanning agents. The in the "Chemisches Zentralblatt" 19o6, page 1854, described, from sulphite pulp waste liquor with chlorinated lime and hydrochloric acid obtained compound of the formula C26 H29 Cl S0.2 is not identical to that obtained according to the present invention. While that compound is only 5.8 Contains percent chlorine and is almost insoluble in alcohol, according to the present invention made product 36 percent chlorine and dissolves with greatest Ease and completely in alcohol.
Beispiel. i oo kg Sulfitzellstoffablauge vom spez. Gew. 1,313 werden mit cool Wasser verdünnt und unter Rühren so lange Chlor eingeleitet, als dasselbe noch leicht aufgenommen wird. Die Flüssigkeit erwärmt sich, wird immer brauner und scheidet schließlich eine braunrote Substanz aus. Diese wird abfiltriert und mit Kochsalzlösung gewaschen. Das Filtrat wird weiter mit Chlor behandelt und liefert weitere Mengen. Die Rückstände werden mit wenig Wasser verrührt und aufgekocht. Hierbei schmilzt die Masse vorübergehend, und! die hellrotbraune Färbung wird dunkler. Man läßt erkalten, saugt ab und wäscht mit Köch'-@ Salzlösung nach.Example. i oo kg of sulphite pulp waste liquor from spec. Weight will be 1.313 diluted with cool water and passed in chlorine while stirring as long as the same is still easily absorbed. The liquid heats up, becomes brown and brown finally a brown-red substance is deposited. This is filtered off and with Washed saline. The filtrate is treated further with chlorine and delivers more quantities. The residues are mixed with a little water and boiled. Here the mass melts temporarily, and! the light red-brown color becomes darker. It is allowed to cool, suctioned off and washed with Köch 'saline solution.
Das so erhaltene Produkt löst sich leicht in Wasser, Äthylalkohol, Methylalkohol. Es ist schwerlöslich in Aceton, unlöslich in Benzol, Solventnaphtba und Dichlorbenzol. Die wässerige Lösung, welche schwach sauer reagiert, läßt sich durch Salzsäure und Kochsalz aussalzen. Sie fällt sehr energisch Leimlösungen. Mit Eisenchlorid gibt sie einen dunkelgraugrünen Niederschlag, auch durch Aluminium- und Chromsalze wird sie gefällt, ebenso durch Salze der alkalischen Erden. Das Produkt enthält wechselnde Mengen Chlor, in diesem Beispiel 36 Prozent. In gleicher Weise lassen sich die aus Sulfitzellstoffablauge gewonnenen, gereinigten Extrakte verwenden.The product thus obtained dissolves easily in water, ethyl alcohol, Methyl alcohol. It is sparingly soluble in acetone, insoluble in benzene, Solvent naphtba and dichlorobenzene. The aqueous solution, which reacts slightly acidic, can salt out with hydrochloric acid and table salt. She very vigorously drops glue solutions. With Ferric chloride gives it a dark gray-green precipitate, also due to aluminum and it is precipitated by salts of chromium, and also by salts of the alkaline earths. The product contains varying amounts of chlorine, in this example 36 percent. In the same way the purified extracts obtained from sulphite pulp waste liquor can be used.
