  Verfahren zur Herstellung eines als Klebstoff sowie als Appretur-, Binde-oder   Laclderungsmittel   dienenden Produktes. 



   Das im Patente Nr. 91006 angegebene Verfahren zur Herstellung eines als Klebstoff sowie als Appretur-,   Binde-oder Laokierungsmittel   dienenden Produktes kann mit Vorteil dahin abgeändert werden, dass die Zelluloseablauge in trockener Form, z. B. in Pulverform, mit schwefelhaltigen Verbindungen, die bei der Zersetzung durch Säuren oder dgl. kolloidalen Schwefel ausscheiden, wie z. B. Natriumthiosulfat, und einer Säure in fester Form, wie Oxalsäure, oder einem sauer reagierenden Salz, z. B. Natriumbisulfat, troeken vermischt wird. 



   Beim Auflösen in Wasser, d. h. bei der Fertigstellung zum technischen Gebrauch, tritt dann die gewünschte Bleichwirkung auf die Zelluloseablauge ein. 



   Das Verfahren der trockenen Mischung zur Herstellung fester hellfarbiger Produkte aus Zellusoseablauge hat grosse technische Vorteile gegenüber dem Eindampfen der nach dem Stammpatent Nr. 91006 
 EMI1.1 
 



   Es ist bereits vorgeschlagen worden, in Sulfitablauge Schwefelwasserstoff einzuleiten, wodurch der Schwefel aus der in der Ablauge vorhandenen schwefeligen Säure und ihren Verbindungen quantitativ gefällt werden soll. Dieses Verfahren bezweckt, den in diesen Verbindungen enthaltenen Schwefel   zurück-   zugewinnen, wobei die Lauge gleichzeitig gereinigt wird, so dass diese nach Entfernung des Schwefels gut weiteren Zwecken zugeführt werden kann.

   Im Gegensatz hiezu werden der Erfindung gemäss getrockneter Zelluloseablauge schwefelhaltige Verbindungen in fester Form zugesetzt, aus denen beim Auflösen in Wasser durch Zersetzung sehr fein verteilter Schwefel kolloidal frei wird, um auf diese Weise-selbst-   verständlich   ohne Entfernung des   Schwefels - hellfarbige Produkte für   den angegebenen Zweck zu gewinnen.

  Process for the production of a product serving as an adhesive and as a finishing, binding or lacquering agent.



   The process given in patent no. 91006 for the production of a product used as an adhesive and as a finishing, binding or laquing agent can advantageously be modified so that the cellulose waste liquor in dry form, e.g. B. in powder form, with sulfur-containing compounds that precipitate when decomposed by acids or the like. Colloidal sulfur, such as. B. sodium thiosulfate, and an acid in solid form, such as oxalic acid, or an acidic salt, e.g. B. sodium bisulfate, is mixed dry.



   When dissolved in water, i.e. H. When it is ready for technical use, the desired bleaching effect occurs on the cellulose waste liquor.



   The process of dry mixing for the production of solid, light-colored products from cellulose waste liquor has great technical advantages over evaporation of the products according to the parent patent no. 91006
 EMI1.1
 



   It has already been proposed to introduce hydrogen sulphide into sulphite waste liquor, as a result of which the sulfur should be precipitated quantitatively from the sulphurous acid and its compounds present in the waste liquor. The purpose of this process is to recover the sulfur contained in these compounds, with the alkali being cleaned at the same time so that it can be used for other purposes after the sulfur has been removed.

   In contrast to this, according to the invention, in accordance with the dried cellulose waste liquor, sulfur-containing compounds are added in solid form, from which, when dissolved in water, very finely divided sulfur is released through decomposition, in this way - of course without removing the sulfur - light-colored products for the specified Purpose to win.
