Patentirt im Deutschen Reiche vom 5. Juli 1898 ab.Patented in the German Empire on July 5, 1898.
Es wurde gefunden, dafs sich die nach dem Verfahren des Patentes Nr. 102458 darstellbaren Aposafraninsulfosäuren leicht und glatt in Safraninfarbstoffe überführen lassen, wenn diese Sulfosäuren mit Ammoniak oder primären Aminen in Reaction gebracht werden. Die Sulfogruppe wird dabei gegen das Amin ausgetauscht, indem sich schweflige Säure abspaltet. Es entstehen nach diesem Verfahren Safranine, die mit den nach dem Verfahren des Patentes Nr. 97118 und der Zusatzpatente auf anderem Wege erhältlichen identisch sind.It has been found that these can be produced by the method of Patent No. 102458 Let aposafraninsulfonic acids easily and smoothly be converted into safranin dyes if these Sulphonic acids are brought into reaction with ammonia or primary amines. The sulfo group is exchanged for the amine, by splitting off sulphurous acid. According to this process, Safranine is created, which with the according to the process of patent no. 97118 and additional patents obtainable by other means are identical.
ι Theil der Isorosindulinsulfosäure folgender Constitution:Part of the isorosindulin sulfonic acid as follows Constitution:
N(C H3J2 N (CH 3 J 2
wird in 10 Theilen Alkohol und 2 Theilen cone. Ammoniak im Autoclaven während 4 Stunden auf ca. 1500 erhitzt. Nach dem Erkalten wird der Alkohol abdestillirt, der Farbstoff in Wasser und Salzsäure gelöst und mit Kochsalz gefällt. Derselbe ist identisch mit dem im Beispiel I des Patentes Nr. 97118 beschriebenen. is made into 10 parts alcohol and 2 parts cone. Ammonia heated in an autoclave for 4 hours to about 150 0th After cooling, the alcohol is distilled off, the dye is dissolved in water and hydrochloric acid and precipitated with common salt. It is identical to that described in Example I of Patent No. 97118.
3 Theile der Isorosindulinsulfosäure folgender Constitution:3 parts of isorosindulin sulfonic acid of the following constitution:
werden in 30 Theilen Alkohol mit 1 Theil p-Phenylendiamin am RUckflufskUhler so lange gekocht, bis die Isorosindulinsulfosäure verschwunden ist. Der Alkohol wird abdestillirt und der Farbstoff als Chlorhydrat isolirt.add 30 parts of alcohol with 1 part of p-phenylenediamine on the reflux condenser for so long cooked until the isorosindulin sulfonic acid is gone. The alcohol is distilled off and the dye is isolated as a hydrochloride.
Beispiel III.Example III.
ι Theil Aposafraninsulfosäure folgender Zusammensetzung :ι Part aposafraninsulfonic acid of the following composition :
wird mit 2 Theilen Anilin bei ca. 1200 digerirt, bis schweflige Säure nicht mehr entweicht. Nach dem Abtreiben des Anilins wird der Farbstoff als Chlorhydrat gelöst und mit Salz gefällt.is digested with 2 parts of aniline at 120 0, no longer escapes to sulphurous acid. After the aniline has been driven off, the dye is dissolved as a hydrochloride and precipitated with salt.
