PATENTAMT.PATENT OFFICE.
Durch Patent 256999 ist ein Verfahren zur Darstellung besonders zur Pigmentfarbenbereitung geeigneter Monoazofarbstoffe geschützt, welches darin besteht, daß man solche Diazoverbindungen der Benzolreihe, welche mindestens eine von der Sulfogruppe verschiedene negative Gruppe enthalten, mit den Arylamiden' der 2 · 3-Oxynaphtoesäure kombiniert. Die so erhaltenen Farbstoffe sind ölunlöslich.Patent 256999 provides a method of representation especially for pigment color preparation Protected suitable monoazo dyes, which consists in the fact that one such diazo compounds the benzene series, which contain at least one negative group different from the sulfo group, with the arylamides' of 2 x 3-oxynaphtoic acid combined. The dyes obtained in this way are insoluble in oil.
Solche Kombinationen aus Diazoverbindungen der Benzolreihe und 2 · 3-Oxynaphtoesäurearylamiden, welche weder im Diazorest noch in der Arylamidgruppe ein negatives Radikal enthalten, sind öllöslich. Es wurde nun gefun den, daß Farbstoffe von wesentlich erhöhter ölechtheit erhalten werden, wenn man Diazoverbindungen der Benzolreihe, welche keine negative Gruppe enthalten, mit solchen 2 · 3 - Oxynaphtoesäurearylamiden kombiniert, welche im Arylrest mindestens eine von der Sulfogruppe verschiedene negative Gruppe, wie Cl oder NO2, enthalten. Hierbei ist die Wirkung in bezug auf Verminderung der öllöslichkeit bei Chloratom pn, welche in meta-Stellung zur Imidgruppe sich befinden, am geringsten. Ortho- oder para-ständiges Chloratom übt einen größeren Einfluß aus.Such combinations of diazo compounds of the benzene series and 2x3-oxynaphthoic acid arylamides, which contain a negative radical neither in the diazo radical nor in the arylamide group, are oil-soluble. It has now been found that dyes of significantly increased oiliness are obtained if diazo compounds of the benzene series which do not contain a negative group are combined with those 2 · 3 - oxynaphthoic arylamides which have at least one negative group different from the sulfo group in the aryl radical, such as Cl or NO 2 . Here, the effect in terms of reducing the oil solubility is lowest with chlorine atoms pn, which are in the meta position to the imide group. Ortho or para chlorine atom has a greater influence.
Lackazofarbstoffe, von ähnlicher ölunlöslichkeit wie die vorliegenden, welche keine Sulfo- oder Carboxylgruppen und auf der Diazoseite des Farbstoffmoleküls keine negative Gruppe enthalten, sind bis jetzt noch nicht bekannt. Die Darstellung der Farbstoffe kann in saurer, neutraler oder alkalischer Lösung vorgenommen werden.Lackazo dyes, of similar oil insolubility like the present ones, which have no sulfo or carboxyl groups and on the diazo side of the dye molecule do not contain a negative group are not yet known. The representation of the dyes can be done in acidic, neutral or alkaline solution will.
12,1 Teile m-Xylidin werden mit 28,5 Teilen Salzsäure 200Be. und 6,9 Teilen Natriumnitrit in üblicher Weise diazotiert und die so erhaltene Diazoverbindung unter gutem Rühren in eine wässerige Suspension von 34,8 Teilen 2 · 3 - Oxy naphtoesäure - 2 · 5 - dichloranilid, bereitet durch Auflösen desselben in verdünnter Natronlauge und Ausfällen mit verdünnter Salzsäure unter Zusatz von Türkischrotöl, der noch 15,9 Teile kalzinierte Soda zugesetzt waren, einlaufen gelassen. Der Farbstoff scheidet sich in tiefroten Flocken aus, er wird nach Vollendung der Kombination abfiltriert, neutral gewaschen und vorteilhaft in Pastenform verwendet. Nach dem Trocknen bildet er ein blaustichig bordeaux Pulver und löst sich in konzentrierter Schwefelsäure mit tief blaustichig roter Farbe.12.1 parts of m-xylidine with 28.5 parts of hydrochloric acid 20 0 Be. and 6.9 parts of sodium nitrite are diazotized in the usual way and the diazo compound thus obtained is mixed with vigorous stirring in an aqueous suspension of 34.8 parts of 2 · 3 - oxynaphthoic acid - 2 · 5 - dichloroanilide, prepared by dissolving it in dilute sodium hydroxide solution and precipitating it Dilute hydrochloric acid with the addition of Turkish red oil to which 15.9 parts of calcined soda were added. The dye separates out in deep red flakes, it is filtered off after completion of the combination, washed neutral and advantageously used in paste form. After drying, it forms a bluish burgundy powder and dissolves in concentrated sulfuric acid with a deep bluish red color.
