Description

Verfahren zur Herstellung von Sulfosäuren Man hat bereits versucht, aus Humussäure künstliche Gerbstoffe herzustellen. Diese Versuche haben aber bisher praktisch keinen Erfolg gehabt, weil die erzielten Stoffe keine gerbenden Eigenschaften aufwiesen.Process for the production of sulfonic acids Attempts have already been made to produce artificial tannins from humic acid. These attempts have so far practically unsuccessful because the fabrics obtained have no tanning properties exhibited.

Es hat sich nun gezeigt, daB sich aus Humussäure praktisch verwendbare Gerbstoffe herstellen lassen, wenn man die Humussäuren mit wasserhaltiger Schwefelsäure bzw. Salzsäure erhitzt und dann weiterverarbeitet. Durch die Säurebehandlung erleiden die Humussäuren eine Umwandlung, möglicherweise tritt eine Hydrolyse ein, welche sie befähigt, Gerbstoffe zu bilden. Praktisch wird das Verfahren derart ausgeführt, daB die Ausgangsstoffe von der Sulfurierung durch rauchende Schwefelsäure in einem geeigneten Lösungsmittel suspendiert und dann bei Gegenwart von wasserhaltiger Schwefelsäure, evtl. unter Druck, erhitzt werden. An Stelle reiner Humussäuren könnten auch humussäurehaltige Stoffe, wie Braunkohle, die mit Alkali ausgezogen ist, verwendet werden.It has now been shown that humic acid can be used in practice Tannins can be produced if the humic acids are mixed with hydrous sulfuric acid or hydrochloric acid and then further processed. Suffer from acid treatment the humic acids a conversion, possibly a hydrolysis occurs, which it enables the formation of tannins. In practice, the procedure is carried out in such a way that that the starting materials of the sulphurisation by fuming sulfuric acid in one suspended in a suitable solvent and then in the presence of hydrous sulfuric acid, possibly under pressure, be heated. Instead of pure humic acids, humic acid-containing ones could also be used Substances such as lignite, which is extracted with alkali, can be used.

Ausführungsbeispiel ioo g Huminsäure, hergestellt aus Braunkohle, werden mit ioo g 66prozentiger Schwefelsäure versetzt und auf dem Ölbade auf etwa =8o° erhitzt. Es entsteht ein wasserunlösliches Produkt. Die so behandelte Huminsäure wird nach Abtrennung der Flüssigkeit mit rauchender Schwefelsäure von 2o °/o S03 auf etwa iio ° erwärmt. Aus der wäßrigen Lösung des Reaktionsprodukts wird die Schwefelsäure entweder durch Zellenfilter oder durch Ausfällen entfernt. Es hinterbleibt nach dem Eindampfen eine braune, wasserlösliche Flüssigkeit, die vorzügliche leimfällende Eigenschaften zeigt und sehr gut als Gerbstoff verwendbar ist.Embodiment 100 g humic acid, made from lignite, are mixed with 100 g of 66 percent sulfuric acid and on the oil bath to about = Heated to 8o °. A water-insoluble product is formed. The so treated humic acid after separation of the liquid with fuming sulfuric acid of 20% SO3 warmed to about 10 °. The aqueous solution of the reaction product becomes sulfuric acid removed either by cell filters or by precipitation. It lingers after evaporation a brown, water-soluble liquid, the excellent glue-precipitating one Shows properties and is very useful as a tanning agent.

Das Produkt kann noch verestert oder chloriert werden.The product can also be esterified or chlorinated.

Man hat zwar bereits vorgeschlagen, Huminsäure zu nitrieren oder zu chlorieren. Auf diese Weise entstehen aber Nitro- bzw. chlorieite Produkte, die sich auf Gerbstöffe nicht weiter verarbeiten lassen.It has already been proposed to nitrate humic acid or to chlorinate. In this way, however, nitro or chlorite products arise that cannot be processed further on tannin.
