KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
In der Patentschrift Nr. 69188 wurde gezeigt, dafs durch Einwirkung von Nitrosodimethylanilin auf m-Amidodimethyl-p-toluidin ein rother basischer Farbstoff von sehr werthvollen Eigenschaften entsteht.In the patent specification No. 69188 it was shown that by the action of nitrosodimethylaniline on m-amidodimethyl-p-toluidine a red basic dye of very valuable value Properties arises.
Wenn man in dem Verfahren der Patentschrift Nr. 69188 das Nitrosodimethylanilin durch Nitrosomonomethyl - ο - toluidin oder Nitrosomonoäthyl-o-toluidin ersetzt, so entstehen basische Farbstoffe von viel rötherer Nuance, als sie die im Haupt - Patent beschriebenen Farbstoffe besitzen. Sie zeigen den Farbenton des Safranins und übertreffen dieses an Seife- und Sodaechtheit. In concentrirter Schwefelsäure lösen sie sich mit grüner Farbe, die beim Verdünnen mit Wasser nach Blau und Roth umschlägt. Aus der wässerigen Lösung des salzsauren Salzes- wird die Basis mit Soda nicht gefällt.When using the nitrosodimethylaniline replaced by nitrosomonomethyl - ο - toluidine or nitrosomonoethyl-o-toluidine, so arise basic dyes of a much redder shade than those described in the main patent Own dyes. They show the color tone of saffranine and surpass it in terms of soap and soda fastness. In concentrated Sulfuric acid dissolve with a green color, which changes to blue and red when diluted with water. From the aqueous solution of the hydrochloric acid salt - the base is not precipitated with soda.
ι 5 kg m-Amidodimethyl-p-toluidin, gelöst in 80 kg Sprit, werden mit 18 kg Nitrosomonoäthyl-o-toluidin und 11 kg Salzsäure von 210B.ι 5 kg of m-amidodimethyl-p-toluidine, dissolved in 80 kg of fuel, with 18 kg of nitrosomonoethyl-o-toluidine and 11 kg of hydrochloric acid of 21 0 B.
mehrere Stunden zum Sieden erhitzt, bis alle Nitrosoverbindung verbraucht ist und der gebildete Farbstoff in wässeriger Lösung die Nuance des Safranins zeigt. Bei genügender Concentration der alkoholischen Lösung krystallisirt der Farbstoff beim Erkalten aus.Heated to the boil for several hours until all the nitroso compound is consumed and the formed Dye in aqueous solution shows the nuance of saffranine. With enough Concentration of the alcoholic solution, the dye crystallizes out on cooling.
Statt in alkoholischer Lösung kann der Farbstoff auch in Essigsäurelösung oder durch Verschmelzen der beiden Componenten erhalten werden.Instead of in alcoholic solution, the dye can also be in acetic acid solution or by Fusion of the two components can be obtained.
Ersetzt man in obiger Vorschrift das Nitrosomonoäthyl-o-toluidin durch die äquivalente Menge Nitrosomonomethyl-o-toluidin, so erhält man einen Farbstoff von etwas gelberer Nuance und ganz ähnlichen Eigenschaften.If the nitrosomonoethyl-o-toluidine is replaced by the equivalent in the above procedure Amount of nitrosomonomethyl-o-toluidine, one obtains a dye with a slightly more yellow shade and very similar properties.
