Description
Verfahren zur Hierstellung von Keratinumwandlungsprodukten Gegenstand der vorliegenden Erfindung ist, ein Verfahren zur Herstellung von, ICeratinumwandlungsprodukten, welches darin besteht, daß man alkalische Keratinlösungen mIt Aldehyden und gegebenenfalls Phenolen behandelt.Process for the preparation of keratin conversion products of the present invention is a process for the preparation of, ICeratin conversion products, which consists in using alkaline keratin solutions with aldehydes and optionally Treated phenols.
Die erfindungsgemäß, erhältlichen Umwandlungsprodukte sind technisch sehr- wertvoll. Sie können z. B. miti sehr gutem Erfolg zur Leimung von Papier, entweder für sich allein oder au-chi in Verbindung mib harzhaltigen oder anderen Leimungsmitteln verwendet. werden. Dabei zeichnen sich die Keratinumwandlungsprodukte der vorliegenden Erfindung gegenüber bekannten, ebenfalls, unter Verwendung von Keratintlösungen hergestellten Papierleimungsmibteln in mannigfacher Weise aus; die Umwanidlungsprodukte werden aus, ihren Usungen, z. B. durch Säuren oder schwefelsaure Tonerde, bei der Papierleimung fast vollsitändig ausgefällt, während demgegenüber die bekannten Keratinlösungen nur langsam und nur zu einem Bruchteil zur Ausfällung kommen; außerdem ist die Leimwirkung bei den erfindungsgemä3 erhältlichen Keratinumwandlungsprodukten größer a2 bei den bekannten Keratinlösungen. Bleispiel 1 ioo Teile einer 2o%#i 'gen alkalischen Keratilllösungw-erden mitt 6T,-#ileneiner4&/oigenwäßrigen el Formaldehydlösung versetzt. Die Reaktionsmischung wird einige Zeit stehengelassen und kann b dann zum Leimen von Papier verwendet werden. An. iStelle von Formal,dehyd kann in gleicher Weise z. R. auch: Acetaldehyd verwendet werden,.The conversion products obtainable according to the invention are technically very valuable. You can e.g. B. with very good success for sizing paper, either on its own or used in conjunction with resinous or other sizing agents. will. The keratin conversion products of the present invention are distinguished in many ways from known paper sizing agents also produced using keratin solutions; the Umwanidlungsprodukte are from their Usungen, z. B. by acids or sulfuric alumina, almost completely precipitated during paper sizing, while the known keratin solutions, on the other hand, only precipitate slowly and only to a fraction; in addition, the glue effect in the case of the keratin conversion products obtainable according to the invention is greater than a2 in the case of the known keratin solutions. Lead Example 1 100 parts of a 20% alkaline keratin solution are mixed with 6% of a 4% aqueous solution of formaldehyde. The reaction mixture is allowed to stand for some time and can be b then used for sizing paper. At. iStelle of formal, dehydration can in the same way z. R. also: acetaldehyde can be used.
Beispiel :2 roo TI--ile einer 2o'/eigen, alkalischen, Keratiinlösung werden mit 2o Teilen einer 4oVoigen Formaldehydlösung und 4 Teilen Kresol versetzt. Die Mischung wird mehrere Sitiunden zum (Sieden erhitzt. Die hierbei erhaltene Losung kann beim Leimen von Papier' dem Holländer unmittelbar ohne Verdünnung zugesetzt werden.Example: 2 roo TI - ile of a 2o '/ own, alkaline, keratin solution 20 parts of a 40% formaldehyde solution and 4 parts of cresol are added. The mixture is heated to boiling for several hours. The resulting solution can be added directly to the Dutchman when gluing paper without thinning will.
BeisPie#I 3 ioo Teile einer 2oO/oigen. alkalischen Keratilir lösung werden in der Hitjze mih 5 Teilen Harz und 2, Teilen Naphthol versetzt; man rü-hrt" bis Auflösung erzielt ist. Hiernach werden io Teile einer 400/04gen wäßrigen Formaldehydlösung zugesetzt. Das gebildete-, sirnpöse Reaktionsgemisch, kann in an -sich, üblicher Weise zumLeimen von Papier verwendet werden.Step Example # I 3 parts of a ioo 2OO / o. alkaline keratilir solution are mixed in the heat with 5 parts of resin and 2 parts of naphthol; the mixture is stirred until dissolution is achieved. After this, 10 parts of a 400/0 mg aqueous formaldehyde solution are added. The sane reaction mixture formed can be used in the usual manner for sizing paper.
