Description

Gerbverfahren Es wurde gefunden, daßAlkylbenzolsulfoclrloride i Hautmaterialien der verschiedensten Arten z auf gerbend wirken und daher mit Vorteil für die Herstellung von Ledern aller Art verwendet werden können.Tanning process has been found to daßAlkylbenzolsulfoclrloride i skin materials of various kinds such act on tanning and can therefore be used with advantage for the production of leathers of all kinds.

DieAlkyll)enzolstrlfoclrloride haben die allgemeine Formel 1z . C6 114 ' S OZ C1 In dieser Formel bedeutet R einen Alkylrest mit mindestens vier Kohlenstoftatonien, z. B. den Butyl-, Amyl-, Hexyl-, Octyl-, \onyl-, Decyl- usw. rest. Diese Reste können geradkettig oder verzweigt sein und primär, sekundär oder tertiär mit dein Benzolrest verbunden sein. R kann auch einen cycloaliphatischen Rest, z. B. den Cyclohexylrest oder den Decahydronaphthalinrest bedeuten. Der lienzolkern kann gegebenenfalls weitere Substituersten, z.li. Halogengruppen, tragen. Die verwendeten Alkylbenzolsulfochloride zeichnen sich dadurch aus, daß sie mit Wasser und wäßrigen Lösungen Emulsionen bilden, aus denen sie leicht und vollkommen von den Hautmaterialien aufgenommen werden. Diese Emulsionen sind sehr haltbar, auch wenn sie Zusatzstoffe, wie z. B. Salze, Säuren, Alkalien u. dgl., enthalten.The alkyl) enzole triflorides have the general formula 1z. C6 114 'S OZ C1 In this formula, R denotes an alkyl radical with at least four carbon tones, z. B. the butyl, amyl, hexyl, octyl, \ onyl, decyl, etc. rest. These leftovers can straight-chain or branched and primary, secondary or tertiary with the benzene residue be connected. R can also be a cycloaliphatic radical, e.g. B. the cyclohexyl radical or mean the decahydronaphthalene radical. The lienzolkern can optionally add further Substituents, e.g. Halogen groups, carry. The alkylbenzenesulfochlorides used are characterized by the fact that they form emulsions with water and aqueous solutions, from which they are easily and completely absorbed by the skin materials. These emulsions are very durable, even if they contain additives such as B. Salts, Acids, alkalis and the like. Contain.

Die Herstellung der Leder erfolgt in an sich bekannter Weise. Die Häute, Felle und Rauchwaren \%"erden in üblicher Weise vorbereitet, d. h. entfleischt, gegebenenfalls geäschert, gebeizt und gepickelt. Die Gerbung kann in Gruben, im Walkfaß oder durch direktesAuftragen.durchgeführt werden.The leather is produced in a manner known per se. the Hides, hides and tobacco products \% "are prepared in the usual way, i.e. fleshed out, if necessary, cremated, pickled and peeled. The tanning can be done in pits, in Full drum or by direct application.

Je nach derArt der herzustellendenLeder können neben den Alkylbenzolsulfochloriden weitere vegetabilische, mineralische oder synthetische Gerbmittel rnitverwendet werden. Auch andere gerbend wirkende Stoffe, wie Formaldehyd oder Tran, können zugesetzt werden. Ebenfalls kann man den Emulsionen zwecks besserer Durchdringung und gegebenenfalls Stabilisierung Netz- und Emulgiermittel zusetzen.Depending on the type of leather to be produced, besides the alkylbenzenesulfochlorides other vegetable, mineral or synthetic tanning agents are also used will. Other substances with a tanning effect, such as formaldehyde or oil, can can be added. You can also use the emulsions for better penetration and, if necessary, add stabilization agents and emulsifiers.

Die Zurichtearbeiten werden wie üblich ausgeführt.The finishing work is carried out as usual.

Beispiel i Kaninfelle werden im Verhältnis 200% Flotte auf das Weichgewicht in eine Emulsion, die ioo g/1 Alkylbenzolsulfochlorid und 5 g/1 Kochsalz enthält, gebracht. Das verwendeteAlkylbenzolsulfochlorid ist eine Mischung von sekundären Decyl-, Dodecyl- und Tetradecylbenzolsulfochloriden. Nach 2 Tagen sind die gerbenden Stoffe restlos von der Haut aufgenommen. Diese zeigte nach üblicher Zurichtung einen guten Ledercharakter. Beispiel e Gebeizfe Blöße wird im Verhältnis i5o% Flotte zum Gewicht der Blöße in eine Emulsion von ioo g/1 des nach Beispiel i verwendeten Alkylbenzolsulfochlorids und 4g/1 Formaldehyd (4o%ig) eingebracht. Darin wird 5 Stunden im Walkfaß bewegt, danach mit 0,75 g/1 Natriumbicarbonat abgestumpft und anschließend über den Bock gehängt. Nach 2 Tagen werden die Leder zum langsamen Trocknen aufgehängt und darin wie üblich zugerichtet.Example i Rabbit skins are made into an emulsion containing 100 g / 1 alkylbenzenesulfochloride and 5 g / 1 common salt in a ratio of 200% liquor to the soft weight. The alkyl benzene sulfochloride used is a mixture of secondary decyl, dodecyl and tetradecyl benzene sulfochlorides. After 2 days, the tanning substances are completely absorbed by the skin. After the usual finishing, this showed a good leather character. Example e Pickled pelt is introduced into an emulsion of 100 g / l of the alkylbenzenesulfochloride used according to Example i and 4 g / l of formaldehyde (40%) in a ratio of 150% liquor to the weight of the pelt. It is agitated in the drum for 5 hours, then blunted with 0.75 g / 1 sodium bicarbonate and then hung over the trestle. After 2 days, the leathers are hung up to dry slowly and then finished as usual.
