Durch Einwirkung von Benzolsulfochlorid auf o-Nitrophenol hat Georgesco (Centralblatt 1900, I, 543) den Benzolsulfosäure-onitrophenolester erhalten. Die Gegenwart weiterer negativer Nitrogruppen im Molekül des ο-Nitrophenols beeinträchtigte, wie er fand, die Reaktion und Trinitrophenol konnte nicht mehr in den Ester übergeführt werden. Es wurde nun gefunden, daß die 2-Nitro-lphenol-4-sulfosäure trotz der negativen Wirkung der Sulfogruppe imstande ist, sich leicht und quantitativ mit Arylsulfochloriden zu verbinden. Es genügt, die alkalische Lösung der o-Nitrophenol-p-sulfosäure bei mäßiger Wärme mit dem Chlorid zusammenzubringen.Through the action of benzene sulfochloride on o-nitrophenol, Georgesco (Centralblatt 1900, I, 543) the benzenesulfonic acid onitrophenol ester obtain. The presence of other negative nitro groups in the ο-nitrophenol molecule affected how he found the reaction and trinitrophenol could no longer be converted into the ester. It has now been found that 2-nitro-1-phenol-4-sulfonic acid despite the negative effect of the sulfo group is able to combine easily and quantitatively with aryl sulfochlorides. Suffice it to use the alkaline solution to bring the o-nitrophenol-p-sulfonic acid together with the chloride at moderate heat.
24,1 kg o-nitrophenolsulfosaures Natron und 10,6 kg Soda werden in 400 1 Wasser gelöst und bei 60 bis 700 C. 19,1 kg p-Toluolsulfochlorid unter energischem Rühren eingetragen. Es entsteht bald eine klare Lösung, aus der sich beim Erkalten das Natronsalz des ρ -Toluolsulf osäure - 2 - nitro - 4- sulf ophenolesters in glänzenden gelblichen Blättchen ausscheidet. Die wäßrige Lösung der Salze ist im Gegen-24.1 kg of o-nitrophenolsulfonic acid and 10.6 kg of soda are dissolved in 400 liters of water and added at 60 to 70 ° C. 19.1 kg of p-toluenesulfonyl chloride with vigorous stirring. A clear solution soon forms, from which the sodium salt of ρ-toluenesulfonic acid - 2 - nitro - 4 - sulfophenol ester precipitates in shiny yellowish flakes when it cools. The aqueous solution of the salts is in contrast

39,5 kg der nach Beispiel 1 erhaltenen Nitrosulfosäure werden allmählich in das kochende Gemisch von 50 kg Eisenspänen, 400 1 Wasser und 2 kg Essigsäure eingetragen. Nach vollendeter Reduktion wird durch Zusatz von Soda alkalisch gemacht, abnitriert und aus dem Filtrat das Natronsalz der gebildeten Aminosäure mit Kochsalz gefällt. Man erhält so glänzende Blättchen des Natronsalzes des ρ-Toluolsulfosäure - 2 - amino-4-sulfophenolesters. Das Natronsalz ist in heißem Alkohol und Aceton löslich und scheidet sich aus diesen Lösungen beim Erkalten wieder ab. In Äther ist es unlöslich. Salzsäure fällt aus der wäßrigen Lösung des Salzes die freie Säure in kristallisierter Form aus. Salpetrige Säure verwandelt sie in die nahezu unlösliche, schwach gelblich gefärbte kristallinische Diazoverbindung, die sehr reaktionsfähig ist und sich leicht mit Aminen und Phenolen verbinden läßt. So erhält man. mit ß-Naphtholdisulfosäure R einen gelblich roten Farbstoff, der durch kurzes Kochen mit verdünnter Natronlauge unter Abspaltung des p-Toluolsulfosäurerestes in einen blauroten Farbstoff übergeführt wird.39.5 kg of the nitrosulfonic acid obtained according to Example 1 are gradually added to the boiling mixture of 50 kg of iron filings, 400 l of water and 2 kg of acetic acid. After finished Reduction is made alkaline by adding soda, nitrided and off The sodium salt of the amino acid formed is precipitated from the filtrate with common salt. You get so shiny flakes of the sodium salt of ρ-toluenesulfonic acid - 2 - amino-4-sulfophenol ester. The sodium salt is soluble in hot alcohol and acetone and separates out these solutions off again when they cool down. It is insoluble in ether. Hydrochloric acid falls the free acid in crystallized form from the aqueous solution of the salt. Nitrous Acid transforms them into the almost insoluble, pale yellowish colored crystalline Diazo compound that is very reactive and easily interacts with amines and phenols can connect. So you get. with ß-naphtholdisulfonic acid R a yellowish red dye, that by briefly boiling with dilute sodium hydroxide solution with cleavage of the p-toluenesulfonic acid residue into a blue-red one Dye is transferred.
Ersetzt man im Beispiel die 19,1 kg ρ-Toluolsulfochlorid durch die gleiche Menge o-Toluolsulfochlorid, so erhält man den ο-To-If you replace the 19.1 kg ρ-toluenesulfochloride in the example by the same amount of o-toluenesulfochloride, one obtains the o-to-
luolsulfosäure-^-amino^-sulfophenolester, der der ρ-Verbindung sehr ähnlich ist, aber sich durch größere Löslichkeit seines Natronsalzes und der Diazoverbindung unterscheidet. Der Farbstoff aus letzterer und ß-Naphtholdisulfosäure R ist etwas gelbstichiger; er wird durch Behandeln mit Natronlauge in denselben Farbstoff verwandelt, der aus der ρ-Verbindung entsteht.luenesulfonic acid - ^ - amino ^ -sulfophenol ester, the is very similar to the ρ-compound, but is distinguished by the greater solubility of its sodium salt and the diazo compound is different. The dye made from the latter and ß-naphthol disulfonic acid R is a bit more yellowish; by treating it with caustic soda, it is transformed into the same dye that is obtained from the ρ-compound arises.
