Verfahren um Hydroxylderivate aromatischer Kohlenwasserstoffe in Wasser löslich zu machen.
Die Verwendbarkeit vieler organischer Hydroxylverbindungen wird dadurch beeinträchtigt, dass die Körper schwer oder gar nicht in Wasser löslich sind. Man hat deshalb schon mehrfach
EMI1.1
fahren der D. R. P. Nr. 148943 und Nr. 160783 Kl. 12 o, diejenige eines bestimmten Ketons. Es war aber bisher nicht, möglich, die Steigerung der Wasserlöslichkeit durch ein allgemeines für alle bezw. eine grössere Anzahl Hydroxylverbindungen anwendbares Mittel zu erreichen.
Es wurde nun ein derartiges Mittel gefunden, welches noch. besonders dadurch wertvoll ist, dass es den gleichen hezw. analogen, chemischen Charakter wie die zu lösenden Körper besitzt, sodass also die chemische Natur des zu lösenden Stoffes durch das zur Lösung benutzte Mittel nicht beeinträchtigt wird.
Das Verfahren besteht darin, dass man die schwer bezw. unlöslichen aromatischen Hydroxil- verbindungen, welche man wasserlöslich machen will, mit solchen Hydroxylverbindungen zu- sammenbringt, welche im Wasser leicht löslich sind. Die Lösung erfolgt dann schon bei ge- wöhnlicher Temperatur und kann durch Erwärmen natürlich noch ebenso gesteigert werden, wie allgemein die Löslichkeit wasserlöslicher Körper.
Beispiel 1. Eine Mischung der verschiedenen Kresole oder Reins-resale wird durch Zusatz der zwei- bis dreifachen Gewichtsmenge Resorzin vollständig wasserlöslich.
Beispiel 2. Ein Gemisch von l kg Resorzin mit 100 g Thymol ist vollständig wasserlö.-ich, auch kann man gleichzeitig je 100 g Benzoesäure und Thymol anwenden.
Beispiel 3. 1 kg Alizarin wird bei gewöhnlicher Temperatur von etwa 60 kg durch wenig Wasserzusatz verflüssigten Phenols mit rotbrauner Farbe gelöst. Beim Eingiessen in das Wasser scheidet sich das Alizarin nur zum Teil wieder aus, ein Teil bleibt mit rosenroter Farbe gelöst.
Beispiel 4. 50 g Guajakol im Gemisch mit 110-120 g Resorzin sind vollständig wasserlöslich.
Beispiel 5. 1 kg Kresol wird in eine Lösung von 4 kg Brenzkatechin in Wasser gegossen.
Die klare Lösung lässt sich beliebig mit Wasser verdünnen.
Beispiel 6. p-Nitrophenol wird durch die ungefähr vierfache Menge Resorzin wasserlöslich.
Das vorliegende Verfahren kann weiter dazu benutzt werden, um die Körper zunächst fest zu transportieren und erst im Augenblick des Gebrauchs zu lösen. Man kann beispielsweise eine Mischung von Resorzin und Kresol oder Resorzin mit Thymol in fester Form herstellen, indem man die Stoffe mischt und gegebenenfalls presst. Wenn man diese Mischungen dann in Wasser bringt, erhält man zunächst konzentrierte Lösungen, die weiter verdünnt werden können. Man kann in dieser Weise Pastillen für Mundwässer, kosmetische Zwecke und dergl. herstellen.

Process to make hydroxyl derivatives of aromatic hydrocarbons soluble in water.
The usability of many organic hydroxyl compounds is impaired by the fact that the bodies are difficult or impossible to dissolve in water. You have therefore already several times
EMI1.1
drive the D. R. P. No. 148943 and No. 160783 class 12 o, that of a certain ketone. However, it was not previously possible to increase the water solubility by a general one for all respectively. to achieve a greater number of hydroxyl compounds applicable agent.
Such a remedy has now been found, which is still. is particularly valuable because it has the same hezw. has an analogous, chemical character as the body to be dissolved, so that the chemical nature of the substance to be dissolved is not impaired by the agent used for the solution.
The procedure consists in that one resp. insoluble aromatic hydroxyl compounds which one wants to make water-soluble are brought together with those hydroxyl compounds which are easily soluble in water. The solution then takes place at the usual temperature and can of course be increased by heating, as can the general solubility of water-soluble bodies.
Example 1. A mixture of the various cresols or pure resale becomes completely water-soluble by adding two to three times the amount by weight of resorcinol.
Example 2. A mixture of 1 kg of resorcinol with 100 g of thymol is completely water-soluble, and 100 g of benzoic acid and thymol can also be used at the same time.
Example 3. 1 kg of alizarin is dissolved at an ordinary temperature of about 60 kg of phenol liquefied by adding a little water and having a red-brown color. When it is poured into the water, the alizarin is only partially excreted; some remains dissolved with a rose-red color.
Example 4. 50 g of guaiacol mixed with 110-120 g of resorcinol are completely soluble in water.
Example 5. 1 kg of cresol is poured into a solution of 4 kg of pyrocatechol in water.
The clear solution can be diluted with water as desired.
Example 6. p-nitrophenol becomes water-soluble with approximately four times the amount of resorcinol.
The present method can also be used to initially transport the body firmly and only to loosen it at the moment of use. For example, a mixture of resorcinol and cresol or resorcinol with thymol can be produced in solid form by mixing the substances and optionally pressing them. If you then bring these mixtures into water, you first get concentrated solutions that can be further diluted. In this way, pastilles for mouthwashes, cosmetic purposes and the like can be produced.
