Nach dem Verfahren des Haupt - Patentes Nr. 44045 werden gelbrothe und rothe Farbstoffe erhalten, indem die Diazoverbindungen von m-Azoxyanilin, m-Azoxy-o-toluidin, m-Azoxy-p-toluidin mit a-Naphtol-a-sulfosäure (Piria), β - Naphtoldisulfosäure (R-Säure), Resorcin, Naphtionsä'ure (Piria), ß-Naphtylaminsulfosäure, a-Naphtylamin oder m-Toluylendiamin gekuppelt werden.Following the process of the main patent no. 44045, yellow-red and red colorants become obtained by the diazo compounds of m-azoxyaniline, m-azoxy-o-toluidine, m-azoxy-p-toluidine with a-naphthol-a-sulfonic acid (Piria), β - naphtholedisulfonic acid (R-acid), resorcinol, Naphthic acid (Piria), ß-naphthylamine sulfonic acid, α-naphthylamine or m-tolylenediamine be coupled.
Nach dem Patente Nr. 54655 werden violette Farbstoffe erhalten, wenn m-Azoxyamine durch p-Azoxyanilin ersetzt werden. Alle diese Farbstoffe besitzen die gemeinsame Eigenschaft, Baumwolle nach einem speciellen Verfahren zu färben.According to patent no. 54655, purple dyes are obtained when m-azoxyamines are carried out p-azoxyaniline can be replaced. All of these dyes have the common property To dye cotton using a special process.
Es gelingt dies in mit Kochsalz beinahe gesättigten Lösungen und in Gegenwart bedeutender Mengen von Aetznatron oder Aetzkalk. Es wurde nun gefunden, dafs, wenn p-Azoxyamine als Diazoverbindungen' auf folgende Naphtalinderivate einwirken, nämlich auf Amidonaphtoldisulfosäure H (Patent Nr. 67062) oder Dioxynaphtalinmonosulfosä'ure S (Patent Nr. 67829) blaue Farbstoffe entstehen., welche sich vorzüglich zum Färben der vegetabilischen Faser eignen. Diese Farbstoffe sind in den Patentschriften Nr. 44045 und 54655 nicht vertreten. Aufserdem besitzen sie gröfsere Affinität zur Faser, so dafs die Ausfärbung ohne Zusatz von Aetznatron stattfindet. Eine Zugabe von Kochsalz ist nur in geringen Mengen (etwa bis zu 5 pCt.) erforderlich.This succeeds more significantly in solutions that are almost saturated with table salt and in the presence Quantities of caustic soda or caustic lime. It has now been found that if p-Azoxyamines act as diazo compounds' on the following naphthalene derivatives, namely on Amidonaphthalene disulfonic acid H (Patent No. 67062) or Dioxynaphthalene monosulfonic acid S (Patent No. 67829) blue dyes arise, which are excellent for coloring vegetable Fiber are suitable. These dyes are not in Patent Nos. 44045 and 54655 represent. They also have a greater affinity for the fiber, so that the coloration takes place without the addition of caustic soda. The addition of table salt is only marginal Quantities (up to about 5 pCt.) Required.
Dabei sind diese Farbstoffe gegen Säuren und Alkalien beständig, so dafs die Farben ziemlich dieselben sind, ob in saurem, neutralem oder alkalischem Bade gefärbt wird.These dyes are resistant to acids and alkalis, so are the colors are much the same whether dyeing is done in an acid, neutral, or alkaline bath.
. Man löst 11,4 kg ρ-Azoxyanilin (Schmelzpunkt 187 bis 1890) in 25 kg Chlorwasserstoffsäure von 20° B. und 100 1 kochendem Wasser, verdünnt die Flüssigkeit mit Eis und Wasser auf 600 1 und giebt ihr 7 kg g8procentiges Natriumnitrit in 21 1 Wasser gelöst zu.. 11.4 kg of ρ-azoxyaniline (melting point 187 to 189 0 ) are dissolved in 25 kg of hydrochloric acid at 20 ° B. and 100 liters of boiling water, the liquid is diluted to 600 liters with ice and water and 7 kg of 8 percent sodium nitrite is added to it 1 dissolved water.
Die so erhaltene Lösung von p-Tetrazoxybenzol dient zu folgenden Paarungen.The solution of p-tetrazoxybenzene thus obtained is used for the following pairings.
Man löst 31,9 kg Amidonaphtoldisulfosäure H und 21 kg kohlensaures Natron in 150 1 Wasser, kühlt die Lösung mit Eis und giebt ihr obige Tetrazolösung unter Umrühren zu. Nach einigen Stunden fällt man den Farbstoff mit 15 kg Kochsalz aus. Er bildet ein schwarzes Pulver, das, in Wasser gelöst, Baumwolle ohne vorhergehendes Beizen sowohl in saurem oder alkalischem als in neutralem Bade dunkelblau färbt.31.9 kg of amidonaphthol disulfonic acid H are dissolved and 21 kg of carbonate of soda in 150 l of water, cool the solution with ice and add the above tetrazo solution with stirring. To The dye is precipitated for a few hours using 15 kg of table salt. He forms a black one Powder which, when dissolved in water, cotton without prior pickling, both in acid or more alkaline than in a neutral bath, it turns dark blue.
Man erhält ebenfalls einen blauen Farbstoff, wenn man im Beispiel I die Amidonaphtol-A blue dye is also obtained, if in example I the amidonaphtol

disulfosäure H (Patent Nr. 67062) durch die Dioxynaphtalinmonosulfosäure S (Patent Nr. 67839) ersetzt. Dieses Verfahren unterscheidet sich von jenen des Patentes Nr. 54116 dadurch, dafsdisulfonic acid H (Patent No. 67062) by the dioxynaphthalene monosulfonic acid S (Patent No. 67839) replaced. This procedure is different of those of Patent No. 54116 in that
1. in dem genannten Patente keine Diazoverbindungen von Azoxyaminen zur Anwendung kommen, und dafs1. No diazo compounds of azoxyamines are used in the patents mentioned come, and that
2. der erhaltene Farbstoff ungeheizte Baumwolle leicht färbt, und zwar mit blauer Farbe, während das Verfahren des Patentes Nr. 54116 zu fuchsinrothen, Wolle in saurem Bade färbenden Farbstoffen führt. Wenn in Beispiel I p-Azoxyorthotoluidin statt p-Azoxyanilin zur Anwendung kommt, so entstehen mit Amidonaphtoldisulfosäure H und mit Dioxynaphtalinmonosulfosäure S blaue Farbstoffe. 2. the dye obtained dyes unheated cotton lightly, with a blue color, while the method of Patent No. 54116 on fuchsia, wool in an acid bath coloring dyes. If in Example I p-azoxyorthotoluidine instead of p-azoxyaniline Is used, so with amidonaphthalene disulfonic acid H and with dioxynaphthalene monosulfonic acid S blue dyes are formed.
