Description

Verfahren zur Behandlung von Holz oder zellulosehaltigen Stoffen zwecks Gewinnung von Zellulose und künstlichem Harz, Lack, Asphalt u. dgl. Gegenstand des Patents 326705 ist ein Verfahren zur Behandlung von Holz oder zellulosehaltigen Stoffen zwecks Gewinnung von Zellulose und künstlichem Harz, Lack, Asphalt _ u. dgl., welches darin besteht, daß man das Ausgangsmaterial mit Phenolen oder Verbindungen mit phenolartigem Charakter in konzentrierter Form oder auch verdünnt, mit Wasser, Alkoholen, Benzol, Benzolderivaten oder Kohlenwasserstoffen der Fettreihe unter Zusatz eines Katalysators erhitzt.A method for the treatment of wood or cellulose-containing materials for the purpose of yielding cellulose and artificial resin, paint, asphalt u. Like. Matter of the patent 326705 is a method for the treatment of wood or cellulose-containing materials for the purpose of yielding cellulose and artificial resin, paint, asphalt _ u The like., which consists in that the starting material with phenols or compounds with phenol-like character in concentrated form or also diluted, heated with water, alcohols, benzene, benzene derivatives or hydrocarbons of the fatty series with the addition of a catalyst.

. Es wurde nun gefunden, daß man je nach den Bedingungen, unter denen der Aufschluß erfolgt, als Katalysator mehr oder weniger große Säuremengen hinzufügen kann, um einen guten Aufschluß zu erhalten, und zwar kann man als Katalysator sämtliche organischen und anorganischen Säuren, sämtliche anorganischen und organischen Stoffe, die unter den Arbeitsbedingungen Säure bil den, wie Ammoniumsalze, Aluminiumchlorid Zinkchlorid, Zinnchlorür, Zinnchlorid, Titan chlorid, Siliziumchlorid, anorganische ünc organische Säurechloride und ähnliche Stoffe endlich Stoffe mit sauren Eigenschaften, wii Nitrophenole, Chlorphenole u. dgl., verwenden. It has now been found that, depending on the conditions under which the digestion takes place when more or less large amounts of acid are added as a catalyst can, in order to obtain a good digestion, and indeed all of them can be used as a catalyst organic and inorganic acids, all inorganic and organic substances, which form acid under the working conditions, such as ammonium salts, aluminum chloride Zinc chloride, tin chloride, tin chloride, titanium chloride, silicon chloride, inorganic ünc organic acid chlorides and similar substances, finally substances with acidic properties, wii use nitrophenols, chlorophenols, and the like
