KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bekanntlich reagirt Anilin mit Rosolsäure unter Bildung eines »Azulin« genannten blauen Farbstoffes. Ebenso erhält man blaue Farbstoffe, wenn man die Rosolsäure mit verschiedenen Diaminen, z. B. p- und m-Phenylendiamin, p- und m-Kresylendiamin reagiren läfst.It is well known that aniline reacts with rosolic acid to form a blue called "azuline" Dye. You also get blue dyes if you mix the rosolic acid with different Diamines, e.g. B. p- and m-phenylenediamine, p- and m-cresylenediamine react running.
„ Es wurde nun gefunden, dafs der Ersatz der aromatischen Amine durch die entsprechenden Hydrazine zu rothen Farbstoffen führt, wenn man 1 Mol. Rosolsäure mit 3 Mol. des betreffenden Hydrazins combinirt. Unter diesen neuen Farbstoffen, für welche die Benennung »Rodazine« vorgeschlagen wird, ist der mit Phenylhydrazin erhaltene wegen seiner lebhaften, schön weinrothen - Färbungen der gewerblich werthvollste.“It has now been found that the replacement the aromatic amines leads to red dyes through the corresponding hydrazines, when 1 mole of rosolic acid is combined with 3 moles of the hydrazine in question. Under these new dyes, for which the name »Rodazine« is suggested, is the one with Phenylhydrazine obtained commercially because of its lively, beautiful wine-red color most valuable.
Zur Darstellung verfährt man z. B. in folgender Weise:To display one proceeds z. B. in the following way:
32,4 kg Phenylhydrazin und 29,2 kg Rosolsäure werden auf dem Wasserbade in eisernem Gefäfs etwa 12 Stunden unter Umrühren auf 70 bis 90° erhitzt; man erhält so den Farbstoff in Gestalt einer braunen Schmelze.32.4 kg of phenylhydrazine and 29.2 kg of rosolic acid are put on the water bath in iron The vessel is heated to 70 to 90 ° for about 12 hours while stirring; the dye is obtained in this way in the form of a brown melt.
Der Farbstoff ist unlöslich in Alkalien, welche ihn in der Wärme entfärben; in concentrirter Schwefelsäure löst er sich mit braungelber Farbe, ebenso in concentrirter Phosphorsäure; in verdünnten Säuren löst er sich mit rother Farbe; mit verdünnter Essigsäure, in welcher der Farbstoff sich sehr leicht löst, erhält man eine schön Bläulich rothe Lösung; in Alkohol und Anilinchlorhydrat ist der Farbstoff ebenfalls leicht löslich.The dye is insoluble in alkalis, which discolor it when heated; in concentrated It dissolves in sulfuric acid with a brownish-yellow color, as in concentrated phosphoric acid; in dilute acids it dissolves with a red color; with dilute acetic acid, in which the dye dissolves very easily, a beautiful bluish red solution is obtained; in alcohol and aniline chlorohydrate, the dye is also readily soluble.
Er färbt Seide und Wolle in schwach essigsaurem Bade lebhaft weinroth, und zwar Seide direct, ebenso Wolle, wenn sie sehr rein ist, sonst in Verbindung mit Natriumaluminatbeize. Die Färbungen sind licht- und seifenecht.He dyes silk and wool vividly wine-red in a weakly acetic acid bath, namely silk direct, also wool, if it is very pure, otherwise in combination with sodium aluminate stain. The colors are lightfast and soapfast.
