Description
Patentiert im Deutschen Reiche vom 27. Juni 1912 ab. Längste Dauer: 26. Juni 1927.Patented in the German Empire on June 27, 1912. Longest duration: June 26, 1927.
In der Patentschrift 272863 ist ein Verfahren zur Darstellung von "Azofarbstoffen, welche Lacke von leuchtenden Nuancen liefern, beschrieben, darin bestehend, daß man die Benzoyl-i · 8-arninonaphtol"4 · 6-disulfosäure mit bestimmten Diazoverbindungen vereinigt. Es wurde nun gefunden, daß man einen Azofarbstoff erhält, der gleichfalls Lacke von sehr großer Klarheit, aber von sehr blaustichiger, nämlich blau violetter Nuance liefert, wenn man an Stelle der in dem Hauptpatent genannten Diazoverbindungen α-Naphtylamin benutzt.In the patent specification 272863 is a method for the preparation of "azo dyes, which Provide lacquers of brilliant shades, described, consisting in the fact that the Benzoyl-i · 8-arninonaphtol "4 · 6-disulfonic acid combined with certain diazo compounds. It it has now been found that an azo dye is obtained which also has very good varnishes great clarity, but with a very bluish tint, namely a blue-violet shade, if one delivers instead of the diazo compounds mentioned in the main patent, α-naphthylamine is used.
In der Patentschrift 180089 sind schon die Lacke aus den Kombinationen der Benzoyl-i · 8-aminonaphtol-4 · 6-disulfosäure mit Anilin-o-sulfosäure, i-Naphtylamin-3 · 8-disulfosäure und p-Chloranilin beschrieben. Alle diese Lacke besitzen aber rote Nuancen, überdies sind die beiden ersteren Farbstoffe nur ganz ungenügend fällbar und liefern daher stark gefärbte Abwässer.In patent 180089, the paints from the combinations of benzoyl-i · 8-aminonaphtol-4 · 6-disulphonic acid with aniline-o-sulphonic acid, i-naphthylamine-3 · 8-disulphonic acid and p-chloroaniline. But all of these paints have red nuances, moreover the first two dyes can only be precipitated very inadequately and therefore yield strongly colored wastewater.

from 143 parts of ct-naphthylamine in conventional
licher Weise hergestellte Diazolösung läßt man unter Rühren einlaufen in eine mit überschüssiger Soda versetzte Lösung von 467 Teilen des Dinatriumsalzes der Benzoylaminonaphtoldisulfosäure 1 · 8 · 4 · 6. Nach beendeter Kombination wird auf etwa 80° aufgewärmt und der Farbstoff, nötigenfalls nach Zusatz von etwas Kochsalz, abfiltriert, gepreßt . und getrocknet. Er bildet ein braun violettes Pulver, das sich in Wasser mit leuchtend rotvioletter Farbe löst. Aus dieser Lösung kön- nen z. B. durch Erdalkalisalze Farblacke von lebhaft rotvioletter Nuance erzeugt werden.Licher way produced diazo solution is allowed to run into an excess with stirring Soda-added solution of 467 parts of the disodium salt of benzoylaminonaphthol disulfonic acid 1 · 8 · 4 · 6. After the combination is complete, it is warmed up to about 80 ° and the dye, if necessary after adding a little common salt, filtered off and pressed. and dried. It forms a brown-purple powder that dissolves in water with a bright red-purple color. From this solution nen z. B. by alkaline earth salts colored lakes of vivid red-violet nuances can be produced.
Die Überführung der Lacke kann nach den für die Lackbereitung üblichen Methoden erfolgen und auch mit der Farbstoffdarstellung vereinigt werden.The paints can be transferred using the methods customary for paint preparation and also be associated with the dye representation.
Paten τ-An Spruch:Godfather τ-An saying:
Abänderung des in der Patentschrift 272863 geschützten Verfahrens, darin bestehend, daß man die Benzoyl-i · 8-aminonaphtol-4 · 6-disulfosäure statt mit den dort verwendeten Diazoverbindungen hier mit derjenigen des a-Naphtylamins kuppelt.Modification of the process protected in patent specification 272863, consisting in that the benzoyl-i · 8-aminonaphtol-4 · 6-disulfonic acid instead of the diazo compounds used there couples with that of a-naphthylamine.
