Description
verfahren zur Darstellung eines Farbstoffes der Phenonaphtosafraninreihe. Es wurde gefunden, dass ein wertvoller, neuer Farbstoff entsteht, wenn man 1-Amino- 4-äthylbenzylanilin-\3-sulfosäure mit 3-Di- -11- methylisorosindulin -1 . 6-disulfo- k iithyl säure der Formel

kondensiert.
Die entstandene Phenonaphto- safranindisulfosäure enthält eine Sulfogruppe in Orthostellung zum Safraninstickstoff (-16-Stellung), wodurch die vorzügliche Al kaliechtheit der Färbungen bedingt wird.
Der neue Farbstoff ist ein dunkles Pulver, das in Wasser mit blauer Farbe, in konzen trierter Schwefelsäure grasgrün löslich ist. <I>Beispiel:</I> 16 Teile 1-Amino-4-äthylbenzylanilin-2- sulfosäure werden mit 3,1 Teilen Soda in 100 Teilen Wasser siedend gelöst und 28 Teile Mononatriumsalz der 3-Diäthyl-ll-methyli- sorosindulin-1. 6-disulfos-äure, sowie 20 Teile Natriumazetat kristallisiert in 200 Teilen Wasser beigefügt. Dann wird während 12 Stunden unter R,ückfluss gekocht, worauf eine Probe, in konzentrierter Schwefelsäure ge löst, eine rein grüne Farbe zeigt.
Der Farb stoff lässt sieh gut aussalzen. Er färbt Wolle aus schwach saurem Bade alkali-, walk- und lichtecht blau. Der Farbstoff entspricht der Konstitution:

process for the preparation of a dye of the phenonaphtosafranin series. It has been found that a valuable, new dye is produced if 1-amino-4-ethylbenzylaniline- \ 3-sulfonic acid with 3-di- -11-methylisorosindulin -1. 6-disulphohydric acid of the formula
EMI0001.0010
condensed.
The resulting phenonaphthosafranine disulphonic acid contains a sulpho group in the ortho position to the safranine nitrogen (-16 position), which is the reason for the excellent alkali fastness of the dyeings.
The new dye is a dark powder that is soluble in water with a blue color, and in concentrated sulfuric acid it is grass-green. <I> Example: </I> 16 parts of 1-amino-4-ethylbenzylaniline-2-sulfonic acid are dissolved with 3.1 parts of soda in 100 parts of boiling water and 28 parts of the monosodium salt of 3-diethyl-II-methylisorosindulin- 1. 6-disulfonic acid and 20 parts of sodium acetate crystallized in 200 parts of water were added. It is then refluxed for 12 hours, whereupon a sample, dissolved in concentrated sulfuric acid, shows a pure green color.
The dye lets you salt out well. It dyes wool from a weakly acidic bath blue, alkali-proof, mill-proof and light-fast. The dye corresponds to the constitution:
