Post (Annalen 205, S. 51) hat durch Einwirkung von rauchender Schwefelsäure auf o-Aminophenol ausschließlich die 2-Amino-1-phenol-4-sulfosäure erhalten. Es wurde nun gefunden, daß eine von dieser verschiedene Säure entsteht, wenn man Carbonylo-aminophenol sulfiert und das Reaktionsprodukt mit verseifenden Mitteln behandelt. Die Diazoverbindung der neuen Säure verbindet sich glatt mit den üblichen Komponenten zu Farbstoffen, die sich vor denen aus der isomeren Säure durch ihre Intensität und Schönheit der Nuance auszeichnen.Post (Annalen 205, p. 51) has due to the action of fuming sulfuric acid o-aminophenol exclusively the 2-amino-1-phenol-4-sulfonic acid obtain. It has now been found that an acid different from this is formed when carbonylo-aminophenol is used sulfated and treated the reaction product with saponifying agents. The diazo compound of the new acid combines smoothly with the usual components to dyes that are distinguished from those from the isomeric acid by their intensity and beauty of the nuance.
Sulfierung von Carbonyl-o-aminophenol. Sulphation of carbonyl-o-aminophenol.
135 kg Carbonyl-o-aminophenol werden bei gewöhnlicher Temperatur in 300 kg Monohydrat gelöst und in diese Lösung 140 kg Oleum (63 Prozent) bei 5 bis 10° allmählich eingetragen. Nachdem die Sulfierung beendet ist, gießt man auf Eis, neutralisiert mit KaIkmilch, filtriert und dampft auf ein Volumen von 1000 1 ein. Man führt sodann in üblicher Weise das Calciumsalz in das Natriumsalz über und fällt letzteres durch Zufügen von Kochsalz aus. Man erhält es so in feinen weißen Nädelchen, die in reinem Wasser leicht löslich, in kochsalzhaltigem schwer löslich sind. ;■■■■■135 kg of carbonyl-o-aminophenol are used Ordinary temperature dissolved in 300 kg of monohydrate and 140 kg in this solution Gradually introduced oleum (63 percent) at 5 to 10 °. After the sulfation has ended is, it is poured onto ice, neutralized with milk milk, filtered and evaporated to volume from 1000 1 a. The calcium salt is then converted into the sodium salt in the usual way and the latter precipitates by adding table salt. It is obtained in fine white needles, those in pure Easily soluble in water, sparingly soluble in saline. ; ■■■■■
Verseifung von Carbonyl-o-aminophenol-5-sulfosäure. Saponification of carbonyl-o-aminophenol-5-sulfonic acid.
237 kg des nach Beispiel 1 erhaltenen Natriumsalzes der Ca'rbonyl-o-aminophenolsulfosäure werden in -750 1 Wasser gelöst und nach Zusatz von 250 kg; Natronlauge (400 Be.) unter Rückfluß gekocht, bis eine Probe keine Zunahme des Diazotiters mehr aufweist. Die klare Lösung wird mit Salzsäure neutralisiert und enthält nun das leicht lösliche Natriumsalz der neuen o-Aminophenolsulfosäure.237 kg of the sodium salt of Ca'rbonyl-o-aminophenolsulfonic acid obtained according to Example 1 are dissolved in -750 1 of water and, after addition of 250 kg; Sodium hydroxide solution (40 0 Be.) Boiled under reflux until a sample no longer shows any increase in the diazotiter. The clear solution is neutralized with hydrochloric acid and now contains the easily soluble sodium salt of the new o-aminophenol sulfonic acid.
Durch weiteren Zusatz von Salzsäure läßt sich die freie Säure in weißen Nadeln abscheiden, die in Wasser ziemlich leicht löslich sind. Mit Nitrit entsteht die in Lösung intensiv gelb gefärbte; Diazoverbindung, die sich aber nach einigem Stehen in langen, grünlichgrauen Nadeln aus der Lösung abscheidet. By adding more hydrochloric acid, the free acid can be separated out in white needles, which are fairly easily soluble in water. With nitrite, the one, which is intensely yellow in color in solution, is formed; Diazo compound that but after standing for some time it separates out of the solution in long, greenish-gray needles.
Die Tatsache, daß man aus der neuen Säure durch Verkochen ihrer' Diazoverbindung bei Gegenwart von Alkohol 1-Phenol-3-sulfosäure erhält, führt zu der Annahme, daß ihr die KonstitutionThe fact that the new acid can be obtained by boiling its' diazo compound Presence of alcohol 1-phenol-3-sulfonic acid receives leads to the assumption that you have the constitution
