Description

Verfahren zur Herstellung von huminartigen Alkaliverbindungen aus alkalischen Braunkohlenextrakten und Sulfitablauge Es wurde: gefunden, .daß durch Dxuck- e:rhitzung . von afkalisclhen Braunkohlen- extrakten und Sulfitablauge braune, humin- @artige Alkaliverbindungen. entstehen, die durch Säure oder saure Salze praktisch rest- los ausfällbar sind und zum Färben von Pa- pier, Pappen u: dg1. verwendet werden kön- nen. Es wird Teuf diese Weise möglich,. Sü1fit- ablaugeeinem hochwertigen Verwendungs- zweck zuzuführen, insbesondere da die Präpa- rate in der Regel auch eine deutlich erkenn- bare leimende Wirkung auf= die fertigen Papier- und Pappanerzeugnisse besitzen. Die Löslichkeit uiid Fällb!arkeit der Pro- dukte hängt von der Menge der verwendeten. Sulfiüablauge ab. Die erfindungsgemäß beanspruchten Koxi densationsp.rodukte können -auch in der Weise gewannen wenden, däß '.die zur Herstellung der Braünkohleanextrakte dienende Braunkohle mit Sulfiüablauge unter Zusatz, von Alkali bei erhöhtem Druck behandelt wird. Sulütoelluloseablau ge in Verbkdung anit Cumaronharzan und in-Verbindung mit einem Hornharzleim. zur Leimung von Papier zu verwenden, ist zwar bekannt: Hieraus war aber nicht abzuleiten, daß die- erfindungs- gemäß vorgenommene Kondensation von Braunkohlenextrakten und Sulfitabläuge einem Farbstoff ergeben würde, der sich besolnder^s zur Anfärbung von Papier eignet und der bleichzeitig im Holländer die Leimung wesent- lich fördert. Ferner war nicht vorauszusehen, daß durch -die Kondensation der @obengenann- ten Komponenten ein Farbstoff herstellbar war; der eine in jeder Hinsicht echte Anfär- bwngergibt. Außerdem ist bereits ein Verfahren be- kannt, bei welchem man die durch Einwir- kung von Salpetersäure auf Braunkohle er- hältlichen Abbiauprodukte mit ligninsulfotn- sawren Salzen. vermengt oder zur -Umsetzung baingt. - Hierbei erhält Iman Geib@mittel. Im Gegensatz hiexzu werden bei @dexn erfindungs- gemäßen Verfahren alkalische Bra2niiohlen, extrakte mit Sulfitablauge unter Drück und Erhitzen ;auf ioo° und darüber kondensiert, wobei man. .die vorbeschriebenen Papierfärhe- und Leimungsmittel erhält.

Die entstandene biraune Lösung wird in üblicher Weise auf Wralzeri . ,getrocknet, und es entsteht ein schwarzes, schuppiges Produkt, :das in Was- ser löslich und durch die üblichen Säure- zusätze im Holländer #fällbar ist.
