KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es wurde gefunden, dafs durch Nilriren von a-Halogenanthrachinonen, wie man sie z. B. nach dem Verfahren des Patentes 131538 erhalten kann, in sehr glatter Weise Paranitrohalogenanthrachinone entstehen, welche Ausgangsmaterialien zu werthvollen grünen Farbstoffen sind.It has been found that by nitrating α-haloanthraquinones, as they are used, for. B. obtained by the method of patent 131538 can arise in a very smooth way Paranitrohalogenanthraquinones, which starting materials are valuable green dyes.
Es ist dieses Verfahren von hohem technischen Werth, da sich hauptsächlich die sehr wichtigen Paraverbindungen bilden, während die zur Darstellung der oben erwähnten Farbstoffe nicht geeigneten Isomeren, deren Bildung unter den gegebenen Bedingungen gerade so wahrscheinlich war, nur in geringerer Menge entstehen.This process is of great technical value, since it is mainly the very important Para connections form, while those for the representation of the above mentioned dyes not suitable isomers, their formation under the given conditions just like that was likely to arise only in smaller quantities.
Das vorliegende Verfahren besteht im Allgemeinen darin, dafs man die Halogenanthrachinone, in Lösungs- oder Suspensionsmitteln vertheilt, mit Salpetersäure behandelt.The present process generally consists in using the haloanthraquinones, distributed in solvents or suspending agents, treated with nitric acid.
Das Verfahren wird durch folgende Beispiele erläutert:The procedure is illustrated by the following examples:
25 kg a-Monoebloranthrachinon werden in 250 kg Schwefelsäure von 66° B. gelöst und mit 8 kg Salpetersäure von 42° B. versetzt, wobei darauf zu achten ist, dafs die Temperatur io° nicht übersteigt. Man läfst die Schmelze bei dieser Temperatur ca. 5 Stunden stehen, dabei scheidet sich das Chlornitroanthrachinon in gelben Nadeln ab. Dieselben werden abgesaugt, ausgewaschen und getrocknet. Durch Umkrystallisiren aus Eisessig erhält man das 1 · 4-Chlornitroanthrachinon in schönen gelben glänzenden Nadeln. Dieselben sind schwer löslich in Alkohol, leicht löslich in Nitrobenzol, schwer löslich in concentrirter Schwefelsäure.25 kg of a-monoebloranthraquinone are used in 250 kg of sulfuric acid of 66 ° B. dissolved and mixed with 8 kg of nitric acid of 42 ° B., Care must be taken that the temperature does not exceed 10 °. You run the Stand the melt at this temperature for about 5 hours, during which the chloronitroanthraquinone separates in yellow needles. The same are suctioned off, washed out and dried. Obtained by recrystallization from glacial acetic acid the 1 · 4-chloronitroanthraquinone in beautiful yellow shiny needles. The same are sparingly soluble in alcohol, easily soluble in nitrobenzene, sparingly soluble in concentrated form Sulfuric acid.
20 kg ι · 5-Dichloranthrachinon werden in 200 kg Schwefelsäure von 66° B. gelöst und bei ο bis 50 mit 10 kg Salpetersäure von 42° B. versetzt. Man läfst dann die Temperatur bis io° steigen, wobei sich ziemlich schnell das 1.5.4. 8-Dichlordinitroanthrachinon krystalünisch abscheidet. Nach einigen Stunden ist die Reaction beendet. Die ausgeschiedenen Krystalle werden abgesaugt, ausgewaschen und getrocknet. Durch Umkrystallisiren aus Nitrobenzol lassen sie sich rein erhalten in Form von gelben Nadeln, welche in Alkohol und Eisessig schwer löslich sind.20 kg · ι 5-dichloroanthraquinone are dissolved in 200 kg of sulfuric acid of 66 ° for example, and added at 0 to 5 ο with 10 kg of nitric acid of 42 ° for example. The temperature is then allowed to rise to 10 °, whereby the 1.5.4. 8-Dichlordinitroanthraquinone separates crystalline. The reaction is over after a few hours. The separated crystals are sucked off, washed out and dried. By recrystallizing them from nitrobenzene, they can be obtained in pure form in the form of yellow needles, which are sparingly soluble in alcohol and glacial acetic acid.
20 kg ι · 5-Dibromanthrachinon werden in 200 kg Schwefelsäure von 66° B. gelöst und bei ο bis 50 mit 8 kg Salpetersäure von 42° B. versetzt. Man läfst dann ohne Kühlung stehen, wobei die Temperatur bis 25° steigt. Das 1.5.4. 8-Dibromdinitroanthrachinon beginnt sich bei ca. 150 krystalünisch abzuscheiden. Nach 2 bis 3 Stunden ist die Reaction beendet. Die ausgeschiedenen Krystalle werden abgesaugt, ausgewaschen und getrocknet. Durch Umkrystallisiren aus Nitrobenzol lassen sie sich rein erhalten in Form von gelben Nadeln, welche in Alkohol und Eisessig schwer löslich sind.20 kg · ι 5-dibromoanthraquinone dissolved in 200 kg of sulfuric acid of 66 ° for example, and added at 0 to 5 ο with 8 kg of nitric acid of 42 ° for example. It is then left to stand without cooling, the temperature rising to 25 °. The 1.5.4. 8-Dibromdinitroanthrachinon begins krystalünisch deposit at about 15 0th The reaction has ended after 2 to 3 hours. The separated crystals are sucked off, washed out and dried. By recrystallizing them from nitrobenzene, they can be obtained in pure form in the form of yellow needles, which are sparingly soluble in alcohol and glacial acetic acid.
Ganz analog verläuft die Nitrirung des 1 · 8-Dichloranthrachinons, sowie der anderen z. B.The nitration of 1 · 8-dichloroanthraquinone proceeds quite analogously, as well as the other z. B.

Man erhält so Paranitrohalogenanthrachinone, welche sämmtlich die charakteristische, technisch äufserst werthvolle Eigenschaft besitzen, beimobtainable by the method of patent 131538 α-haloanthraquinones. This gives paranitrohalogenanthraquinones, which all possess the characteristic, technically extremely valuable property, at
