KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
An Stelle des Ammoniaks lassen sich im "Verfahren des Haupt-Patentes auch substituirte Ammoniakbasen, z. B. Methylamin, Diäthylamin, ferner aromatische Amine, insbesondere Anilin und o-Toluidin verwenden. Man erhält so gleichfalls blaue bis grünblaue, in Wasser schwer lösliche Farbstoffe, welche denjenigen des Haupt-Patentes sehr ähnlich sind.Instead of ammonia, it is also possible to substitute ammonia in the process of the main patent Ammonia bases, e.g. B. methylamine, diethylamine, also aromatic amines, especially aniline and use o-toluidine. This also gives blue to green-blue ones in water sparingly soluble dyes, which are very similar to those of the main patent.
10 kg des nach § a der Patentschrift Nr. 67102 dargestellten, leicht im Wasser löslichen Farbstoffes werden mit 50 bis 100 kg Anilin auf 190 bis 200° C. während 5 bis 6 Stunden bezw. so lange erhitzt, bis die Umwandlung in schwer löslichen, beim Eingiefsen einer Probe in Wasser und Ansäuern ausfallenden Farbstoff beendet ist. Man giefst alsdann die Schmelze in Wasser, kocht auf, säuert mit Salzsäure an, filtrirt und wäscht den Rückstand mit Wasser behufs Entfernung des überschüssigen salzsauren Anilins. Behufs feinerer Vertheilung wird er in Natronlauge gelöst, mit Salzsäure wieder gefällt und ausgewaschen. 10 kg of the easily soluble in water shown according to § a of the patent specification No. 67102 Dye with 50 to 100 kg of aniline to 190 to 200 ° C. for 5 to 6 hours or Heated until the transformation into poorly soluble, when pouring dye precipitating in a sample in water and acidification has ended. You pour then the melt in water, boils, acidified with hydrochloric acid, filtered and washed the residue with water to remove the excess hydrochloric aniline. Attention finer distribution it is dissolved in caustic soda, precipitated again with hydrochloric acid and washed out.
In gleicher Weise vollzieht sich die Ueberführung des nach §c der Patentschritt Nr. 67102 dargestellten, nach Patentschrift Nr. 71435 in trockener Form isolirten wasserlöslichen Farbstoffes in ein schwer lösliches Anilinderivat. The transfer of the patent step no. 67102 according to §c takes place in the same way shown, isolated in dry form according to Patent No. 71435 Dye into a poorly soluble aniline derivative.
Ersetzt man in obigem Beispiel das Anilin durch o-Toluidin, indem man zugleich die Temperatur etwas höher hält (zweckmäfsig etwa 205 bis 2100C), so entstehen die analogen Toluidinderivate. Replacing the aniline by o-toluidine in the above example, by at the same time keeps the temperature slightly higher (zweckmäfsig about 205-210 0 C), the analog toluidine arise.
Die speciellen Eigenschaften der gewonnenen Farbstoffe, welche alle chromgebeizte Wolle in schönen grünblauen Tönen anfärben, sind aus folgender Zusammenstellung ersichtlich:The special properties of the dyes obtained, all of which are chrome-stained wool Coloring in beautiful green-blue tones can be seen from the following list:
