KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Es wurde beobachtet, dafs sich in dem Verfahren der Patentschrift 123613 die Amidobenzylbasen ersetzen lassen durch das p-Amidobenzylpyridinchlorid von der Formel:It has been observed that the amidobenzyl bases are used in the process of patent specification 123613 can be replaced by the p-amidobenzylpyridine chloride from the formula:

N-ClN-Cl

CHCH

NH2,NH 2 ,

ferner durch den Körper, welcher bei Behandlung des p- Amidobenzylpyridinchlorids mit Aetzalkali, Soda oder Natriumacetat nach Lellmann & Pekrun, Ann. 25g, 57 erhalten wird und durch das »Benzylenirm'd« von Thiele & Weil, Ber. 28, 1650 von der Zusammensetzung C8 ii,8 2V4.also through the body, which when p-amidobenzylpyridine chloride is treated with caustic alkali, soda or sodium acetate according to Lellmann & Pekrun, Ann. 25g, 57 is obtained and by the "Benzylenirm'd" by Thiele & Weil, Ber. 28, 1650 of the composition C 8 ii, 8 2V 4 .

Bei Behandlung der in der Patentschrift 123613 im Einzelnen angeführten Farbstoffe mit dem ρ - Amidobenzylpyridinchlorid tritt freies Pyridin auf, so dais angenommen werden mufs, dafs das p-Amidobenzylpyridinchlorid zunächst in den von Lellmann & Pekrun, Ann. 259, 57 beschriebenen Körper übergeht. Die Constitution des diesem Körper sehr ähnlichen »Benzylenimid« von Thiele &Weil kann vielleicht durch die Formel:When treating the dyes detailed in patent specification 123613 free pyridine occurs with the ρ-amidobenzylpyridine chloride, so that it is assumed must be that the p-Amidobenzylpyridinchlorid first in the of Lellmann & Pekrun, Ann. 259, 57 passes over. The very constitution of this body similar "Benzylenimid" from Thiele & Weil can maybe through the formula:

NH2 <( ) — CH2 — NH ζ y -CH = NH 2 <() - CH 2 - NH ζ y -CH =

CH^ > — NH- CH2 — < > — NH2 CH ^ > - NH- CH 2 - <> - NH 2

ausgedrückt werden, und so würde dieser Körper eine complexe p-Amidobenzylbase darstellen, als welche wohl auch der durch Behandeln von p-Amidobenzylpyridinchlorid mit Alkali erhaltene Körper angesehen werden kann.be expressed, and so this body would represent a complex p-amidobenzyl base, which the body obtained by treating p-amidobenzylpyridine chloride with alkali are probably also regarded as can.

Die Behandlung der Farbstoffe mit diesen Basen erfolgt durch Erwärmen in neutraler oder schwach saurer Lösung. Bei Anwendung des ρ-Amidobenzylpyridinchlorids tritt starker Geruch nach Pyridin auf. Es entstehen in jedem Fall Producte, welche den in der Patentschrift 123613 beschriebenen sehr ähnlich sind.The treatment of the dyes with these bases is carried out by heating in neutral or weakly acidic solution. When using the ρ-amidobenzylpyridine chloride occurs more strongly Smell of pyridine. In any case, products are created which correspond to the Patent 123613 described very similar are.

Bei der Behandlung der Farbstoffe in Substanz werden sehr schwer lösliche Producte erhalten, weshalb sich das Verfahren vornehmlich zur Anwendung auf der Faser eignet. Die so erhaltenen Färbungen sind dann ebenso wasser- und waschecht, wie die durch Behandlung mit den Amidobenzylanilinbasen erhaltenen. In gleicher Weise wird durch Nachbehandlung der sogen. Congofarben die Säure-In the treatment of the dyestuffs in substance, products are very difficult to dissolve received, which is why the process is primarily suitable for use on the fiber. The dyeings obtained in this way are then just as water- and washfast as those obtained through treatment obtained with the amidobenzylaniline bases. In the same way is done by post-treatment the so-called Congo colors the acid

empfindlichkeit gemildert bezw. aufgehoben. Das allgemeine Verfahren zur Anwendung der Basen ist dasselbe, wie es für die Amidobenzylanilinbasen in der Patentschrift 123613 beschrieben wurde.sensitivity mitigated resp. canceled. The general procedure for applying the Bases is the same as described for the amidobenzylaniline bases in patent 123613 became.
