4. 34 Teile des Kondensationsproduktes aus Chloranil und p-Chloranilin werden, wie in Beispiel 3, mit Schwefelkohlenstoff und Pyridin zum Sieden erhitzt.
Der Farbstoff färbt Wolle in leuchtend rötlichbraunen Nuancen.
5. 33 Teile des Kondensationsproduktes aus Chloranil und p-Toluidin werden, wie in Beispiel 3, mit Schwefelkohlenstoff und Pyridin zum Sieden erhitzt. Der Farbstoff färbt Wolle rotbraun.
An Stelle von Pyridin können auch andere Verdünnungsmittel genommen werden.
In ähnlicher Weise reagiert Kohlenoxysulfid.
6.200 Teile des Kondensationsproduktes aus Chloranil und Anilin werden mit
1600 Teilen 950/obigem Alkohol und etwa 400 Teilen kristallisiertem Natriumthiosulfat in einem mit Rührer versehenen Autoklaven 8 Stunden auf 170 bis 175 geheizt. Nach dem Erkalten wird der Bombeninha filtriert, der schwarze Rückstand mit Wasser mehrmals ausgekocht und mit verdünnter Salzsäure und Wasser gewaschen. Der Farbstoff bilas in getrocknetem Zustande ein schwarzes, in den meisten organischen Lösungsmitteln

4. 34 parts of the condensation product of chloranil and p-chloroaniline are heated to the boil with carbon disulfide and pyridine, as in Example 3.
The dye dyes wool in bright reddish brown shades.
5. 33 parts of the condensation product of chloranil and p-toluidine are heated to the boil with carbon disulfide and pyridine, as in Example 3. The dye dyes wool reddish brown.
Other diluents can be used in place of pyridine.
Carbon oxysulphide reacts in a similar way.
6,200 parts of the condensation product of chloranil and aniline are with
1600 parts of 950 / above alcohol and about 400 parts of crystallized sodium thiosulphate were heated to 170 to 175 hours in an autoclave equipped with a stirrer. After cooling, the bomb content is filtered, the black residue is boiled several times with water and washed with dilute hydrochloric acid and water. The dye bilas in the dried state a black, in most organic solvents
EMI2.1
The dyeings have very good fastness.
7. 76 parts of the condensation product of chloranil and aniline are heated to 150 to 155 "with 600 parts of 95% alcohol and 120 parts of crystallized sodium thisulfate for 12 hours. The bomb content is worked up as in Example 6 and the residue is concentrated after drying cold sulfuric acid, it dyes wool in really strong brown-black tones.
If in Example 6 or 7, instead of the condensation product from chlorine
EMI2.2
the resulting dyes are much redder.
8,100 parts 2. 5-dichloro-3. 6-dianilidocbinoD, 1200 parts of water and 200 parts of crystallized sodium thiosulphate are heated to 1: 00 to 15: 0 in an autoclave for 10 hours. The dye, worked up as in Example 6, was strongly colored wool.
Other diluents can be used instead of alcohol
9.40 parts of 2,5-dichloro-3,6-dianilidoquinone, 300 parts of pyridine and 3 parts of dehydrated sodium thiosulfate are heated to boiling for 5 hours. After cooling, it is filtered and the residue is boiled with alcohol. The dye isolated in this way is a brownish-gray crystal powder and dyes wool in strong, dark brown-gray real nuances.
