KAISERLICHESIMPERIAL
Nach dem durch das Hauptpatent 211869 geschützten Verfahren werden Aralkyl-p-aminophenole in der Weise erhalten, daß man die Kondensationsprodukte aus aromatischen Aldehyden und p-Aminophenol mittels Zink und Alkali reduziert. Es wurde nun gefunden, daß man an Stelle des p-Aminophenols auch dessen Kernsubstitutionsprodukte verwenden und in analoger Weise, durch Reduktion der entsprechenden Kondensationsprodukte mit aromatischen Aldehyden von der allgemeinen Formel: OH · Rx- N: CH■ R2(R1 = substituiertes Phenyl, A2 = Aryl oder substituiertes Aryl) zu den entsprechenden Aralkylderivaten gelangen kann.According to the process protected by the main patent 211869, aralkyl-p-aminophenols are obtained in such a way that the condensation products of aromatic aldehydes and p-aminophenol are reduced by means of zinc and alkali. It has now been found that, instead of the p-aminophenol, its core substitution products can also be used and, in an analogous manner, by reducing the corresponding condensation products with aromatic aldehydes of the general formula: OH · R x - N: CH · R 2 (R 1 = substituted phenyl, A 2 = aryl or substituted aryl) can lead to the corresponding aralkyl derivatives.
4-Benzylamino-3-chlor-i-oxybenzol (N - Benzyl-4-amino-3-chlor-i-phenol). 4-Benzylamino-3-chloro-i-oxybenzene (N - Benzyl-4-amino-3-chloro-i-phenol).
10 g 3-Chlor-4-amino-i-phenolsulfat (vgl. Patentschrift 143449, Kl. 12 q) werden mit 10 g Kaliumacetat in .200 ecm Wasser gelöst und mit 5,5 g Benzaldehyd 3 Stunden bei Zimmertemperatur gut verrührt. Hierbei entsteht Benzyliden^-amino-s-chlorphenol, das bei 180 bis 181 ° schmilzt, in heißem Alkohol leicht, in kaltem schwerer und in verdünnter Essigsäure und Wasser unlöslich ist. Es wird abgesaugt, mit Wasser gewaschen und ohne weitere Reinigung der Reduktion unterworfen, indem man es in überschüssiger 20 prozentiger Natronlauge löst, mit 10 g Zinkstaub versetzt und anfangs bei Zimmertemperatur, darauf bei 50 ° so lange rührt, bis die gelbe Farbe der Lösung in Grau übergegangen ist. Dann wird die Mischung mit Salzsäure sauer gemacht (bis zur Reaktion auf Congo), mit Wasser und Tierkohle versetzt, aufgekocht und heiß filtriert. Aus der genügend sauren Lösung fällt beim Erkalten und Zusatz von Chlorammonium das Chlorhydrat des N-Benzyl-4-amino-3-chlorphenols in derben Kristallen aus. Da dieses Salz von Wasser leicht hydrolysiert wird, muß beim Umlösen stets für einen Überschuß von Salzsäure gesorgt werden. Es schmilzt unter geringer Zersetzung bei 195 °. Versetzt man die wäßrige Lösung mit Natriumsulfit, so fällt die Base als öl aus, welches leicht löslich in Äther, Alkohol Und verdünntem Alkali, wenig löslich in Wasser und Sodalösung ist. Die Base konnte bisher nicht kristallisiert erhalten werden.10 g of 3-chloro-4-amino-i-phenol sulfate (see patent specification 143449, class 12 q) are dissolved with 10 g of potassium acetate in .200 ecm of water and stirred well with 5.5 g of benzaldehyde for 3 hours at room temperature. This creates Benzylidene ^ -amino-s-chlorophenol, which is at 180 melts up to 181 °, easily in hot alcohol, is insoluble in cold heavy and in dilute acetic acid and water. It is sucked off, washed with water and, without further purification, subjected to reduction by placing it in excess of 20 percent Sodium hydroxide solution, mixed with 10 g zinc dust and initially at room temperature, then stirred at 50 ° until the yellow color of the solution has turned gray. then the mixture is made acidic with hydrochloric acid (until it reacts to Congo), water and animal charcoal are added, and the mixture is boiled and filtered hot. From the sufficiently acidic solution falls on cooling and adding Chlorammonium the hydrochloride of N-benzyl-4-amino-3-chlorophenol in coarse crystals the end. Since this salt is easily hydrolyzed by water, it must always be used for one when dissolving Excess hydrochloric acid should be taken care of. It melts at 195 ° with little decomposition. If the aqueous solution is mixed with sodium sulfite, the base precipitates as an oil, which Easily soluble in ether, alcohol and dilute alkali, slightly soluble in water and soda solution is. Up to now, the base could not be obtained in crystallized form.
4 - Benzylamino-3-methyl-I-oxybenzol (N - Ben-4 - Benzylamino-3-methyl-I-oxybenzene (N - Ben-
zyl-4-amino-3-methyl-i-phenol).
17,2 g 3-Methyl"4-aminophenolsulfat werden in 300 ecm Wasser gelöst, mit 15 g Kaliumacetat
und ir g Benzaldehyd 3 Stunden lang gerührt. Das ausgefallene Benzyliden-4-amino-3-methylphenol,
das sich gut aus heißem Alkohol umlösen läßt und dann bei 133 °zyl-4-amino-3-methyl-i-phenol).
17.2 g of 3-methyl "4-aminophenol sulfate are dissolved in 300 ecm of water, stirred for 3 hours with 15 g of potassium acetate and 1 g of benzaldehyde. The precipitated benzylidene-4-amino-3-methylphenol, which dissolves easily from hot alcohol leaves and then at 133 °
schmilzt, wird in überschüssiger 20 prozentiger Natronlauge gelöst und mit 15 g Zinkstaub so länge bei 50 ° gerührt, bis die gelbe Farbe in Grau umschlägt. Beim Abkühlen wird die Masse fest durch Ausscheidung des Natriumsakes vom N-Benzyl-^amino-s-methylphenol, welches in kalter Natronlauge schwer löslich ist. Das ausgeschiedene Salz wird in Wasser gelöst und vom unverbrauchten Zinkstaub abfiltriert. In die wäßrige Lösung wird Salzsäure bis zur Reaktion auf Congo gegeben, worauf mit Tierkohle versetzt, gekocht und filtriert wird. Beim Abkühlen scheidet sich das Chlorhydrat des N-Benzyl-4-amino-3-methylphenols ab; es fällt leicht als öl, auch aus saurer Lösung aus, und kann in üblicher Weise in Knstallform übergeführt werden. Das Chlorhydrat schmilzt bei 220 ° unter geringer Zersetzung, ist gut in heißem, schwer in kaltem Wasser löslich. Die mit Natriumsulfit freigemachte Base, die in Alkohol und Äther leicht löslich ist, läßt sich aus einem Gemisch von Benzol und Petroläther umlösen und schmilzt dann bei 84".melts, is dissolved in excess 20 percent sodium hydroxide solution and mixed with 15 g of zinc dust stirred at 50 ° until the yellow color turns gray. When it cools down, the Mass solid by excretion of the sodium sake from N-benzyl- ^ amino-s-methylphenol, which is sparingly soluble in cold caustic soda. The excreted salt is in water dissolved and filtered off from the unused zinc dust. Hydrochloric acid is added to the aqueous solution given until the reaction to Congo, whereupon animal charcoal is added, boiled and is filtered. The N-benzyl-4-amino-3-methylphenol chlorohydrate separates on cooling away; It is easily precipitated as an oil, even from an acidic solution, and can be used in the usual way to be transferred to Knstallform. The chlorine hydrate melts at 220 ° with little decomposition, dissolves well in hot water and poorly in cold water. The one cleared with sodium sulfite Base, which is easily soluble in alcohol and ether, can be dissolved from a mixture of benzene and petroleum ether and then melts at 84 ".
Analog verfährt man, wenn man andere Substitutionsprodukte des p-Aminophenols oder anderer aromatischer Aldehyde anwendet.The procedure is analogous if you have other substitution products of p-aminophenol or uses other aromatic aldehydes.
Die neuen Verbindungen sollen für photographische und andere technische Zwecke Verwendung finden.The new compounds are intended to be used for photographic and other technical purposes Find.
