Läßt man auf die Diacetylverbindung des m-m'-Dichlorbenzidins (N H2: Cl = ι : 3) die zwei Molekülen entsprechende Menge Salpetersäure einwirken, so erhält man nach der Verseifung des Reaktionsproduktes ein Dichlordinitrobenzidin, dem wahrscheinlich die Konstitution :If the diacetyl compound of m-m'-dichlorobenzidine (NH 2 : Cl = ι: 3) is allowed to act in the amount of nitric acid corresponding to two molecules, a dichlorodonitrobenzidine is obtained after the saponification of the reaction product, which probably has the constitution:

Es wurde nun gefunden, daß die Tetrazoverbindung dieses Dichlordinitrobenzidins bei der Kombination mit 2 Molekülen ß-Naphtol einen roten Disazofarbstoff liefert, der wegen seiner Wasserunlöslichkeit und hervorragenden ölechtheit zur Darstellung von Pigmentfarben sehr geeignet ist.It has now been found that the tetrazo compound of this dichloro nitrobenzidine the combination with 2 molecules of ß-naphtol produces a red disazo dye, which because of its insolubility in water and excellent oiliness for the representation of pigment colors is very suitable.
Der Monoazofarbstoff der Patentschrift 202908 aus 5-Chlor-2-nitroanilin, der ähnliche Konstitution besitzt, ist bekanntlich nicht vollständig ölunlöslich. Es konnte deshalb nicht vorausgesehen werden, daß das vorliegende Benzidinderivat einen so hervorragend ölechten Disazofarbstoff liefern würde.The monoazo dye of patent 202908 from 5-chloro-2-nitroaniline, the similar one Has constitution, is known to be not completely oil-insoluble. It could therefore the present benzidine derivative cannot be foreseen to make one so excellent would provide oleic disazo dye.

Darstellung des Dichlordinitrobenzidins. Representation of the dichloroditrobenzidine.
m - m' - Dichlorbenzidin wird in üblicher Weise in die Diacetylverbindung übergeführt. 16,8 Teile des erhaltenen m-m'-Dichlordiacetylbenzidins werden unter guter Kühlung in 100 Teilen Schwefelsäure von 66° Be. gelöst, worauf zu der Lösung bei 0 bis 50 die zwei Molekülen entsprechende Menge Nitriersäure allmählich zufließen gelassen wird. Hierauf steigert man die Temperatur langsam auf 200 und gießt dann das Reaktionsgemisch in Eiswasser. Dabei scheidet sich das Dichlordinitrodiacetylbenzidin aus; es wird abfiltriert und durch Erwärmen mit 25 prozentiger Schwefelsäure verseift. Das Dichlordinitrobenzidin bildet ein gelbes Pulver und schmilzt bei ungefähr 255 ° C.m - m '- dichlorobenzidine is converted into the diacetyl compound in the usual way. 16.8 parts of the m-m'-dichlorodiacetylbenzidine obtained are in 100 parts of sulfuric acid at 66 ° Be with good cooling. dissolved, whereupon the amount of nitrating acid corresponding to two molecules is gradually allowed to flow into the solution at 0 to 5 0. The temperature is then slowly increased to 20 0 and the reaction mixture is then poured into ice water. The dichloronitrodiacetylbenzidine separates out; it is filtered off and saponified by heating with 25 percent sulfuric acid. The dichloroditrobenzidine forms a yellow powder and melts at about 255 ° C.

Darstellung des Farbstoffs.Representation of the dye.
34,3 Teile Dichlordinitrobenzidin werden mit 200 Teilen Wasser und 80 Teilen Salzsäure von 20° Be. fein angeschlämmt und mit einer Lösung von 14 Teilen Natriumnitrit versetzt. Die, wenn nötig, nitrierte Diazolösung läßt man zu einer Suspension von 29 Teilen ß-Naphtol, die durch Fällen einer Lösung der ent-34.3 parts of dichlorodonitrobenzidine are mixed with 200 parts of water and 80 parts of hydrochloric acid from 20 ° Be. finely slurried and mixed with a solution of 14 parts of sodium nitrite. The, if necessary, nitrated diazo solution is added to a suspension of 29 parts of ß-naphtol, by finding a solution to the
sprechenden Menge ß-Naphtolnatrium in 500 Teilen Wasser bei Gegenwart von Türkischrotöl erhalten wurde, und der noch 140 Teile Natriumacetat zugefügt waren, fließen. Der Farbstoff bildet sich rasch und scheidet sich in roten Flocken aus. Er wird abfiltriert, mit Wasser gewaschen und vorteihaft in Pastenform verwendet.speaking amount of ß-naphtol sodium in 500 Parts of water was obtained in the presence of Turkish red oil, and that still 140 parts Sodium acetate were added, flow. The dye forms and separates quickly in red flakes. It is filtered off, washed with water and advantageously in Paste form used.
Statt des Türkischrotöls können auch andere ähnlich wirkende Stoffe, z. B. Seife oder Harzleim, zugesetzt werden, oder es kann die Kombination bei Abwesenheit eines dieser Stoffe ausgeführt werden. Selbstverständlich kann man die Kupplung der Tetrazoverbindung mit ß-Naphtol auch bei Gegenwart eines Substrats vornehmen.Instead of Turkish red oil, other substances with a similar effect, e.g. B. Soap or resin glue, can be added, or the combination can be carried out in the absence of one of these substances. Of course you can the coupling of the tetrazo compound with ß-naphtol in the presence of a Make the substrate.
