Description
Zusatzpatent zum Hauptpatent Nr. 136649. Verfahren zur Herstellung eines neuen ehromhaltigen Farbstoffes. Es wurde gefunden, dass man einen neuen wertvollen ehromhaltigen Farbstoff erhält, wenn man den Azofarbstoff aus di- azotierter 2--Amino-l-oxyna.pihthalin-4,8-di- sulfosäure und 2-Amino-5-oxynaphthalin-7- sulfosäure mit chromabgebenden Mitteln und mit einem Oxydationsmittel behandelt, wobei diese beiden Operationen nicht gleich zeitig,
sondern nacheinander durchgeführt 21 werden. Der erhaltene chromhaltige Farbstoff bildet getrocknet ein dunkles P-Ltlv'er, welches in Wasser und in verdünnter Sodalösung mii blauer und in konzentrierter Schwefelsäure mit rötlichschwarzer Farbe löslich ist. Er färbt vegetabile Fasern aus neutralem Glaubersalzbade in echten grünblauen Tö nen an.
<I>Beispiel:</I> Die<B>7</B> Teilen Natriumnitrit entsprechende Menge Diazoverbindung der 2-Amino-1.-ox- ,v- naphthalin-4,8-disuliosäure wird in Gegen wart von Soda oder Ammüniak mit<B>23,9</B> Teilen 2-Amino-5-oxynaphthalin-7-sulfosäure kombiniert und der gebildete Farbstoff durch Kochen mit einer Fluorchromlösung, entspre- o'hend <B>15</B> Teilen Cr#01" in die Chromverbin dung übergeführt.
Diese wird mit Soda. alka lisch gestellt und vom Chromsc'hlamm durch Filtrieren befreit. Die Farbstofflösung wird darauf mit einer Alkaliliypoehloritlösung, entsprechend<B>1,0</B> bis<B>15</B> Teilen aktivem Chlor, versetzt und nach beendeter Reaktion der neue Farbstoff durch Eindampfen gewonnen.
Additional patent to main patent No. 136649. Process for the production of a new Ehrom-containing dye. It has been found that a new valuable Ehrom-containing dye is obtained if the azo dye is obtained from diacotized 2 - amino-1-oxyna.phthalene-4,8-disulfonic acid and 2-amino-5-oxynaphthalene-7- sulfonic acid treated with chromium-releasing agents and with an oxidizing agent, these two operations not being carried out simultaneously,
but be carried out one after the other 21. When dried, the chromium-containing dye obtained forms a dark P-Ltlv'er, which is soluble in water and in dilute soda solution with blue and in concentrated sulfuric acid with a reddish black color. It colors vegetable fibers from neutral Glauber's salt bath in real green-blue tones.
<I> Example: </I> The <B> 7 </B> parts of sodium nitrite corresponding amount of diazo compound of 2-amino-1.-ox-, v-naphthalene-4,8-disulioic acid is in the presence of soda or Ammüniak combined with <B> 23.9 </B> parts of 2-amino-5-oxynaphthalene-7-sulfonic acid and the dye formed by boiling with a fluorochrome solution, corresponding to <B> 15 </B> parts of Cr # 01 "transferred to the chrome compound.
This is made with soda. alkaline and freed from chrome lamb by filtering. The dye solution is then mixed with an alkali metal polypolorite solution, corresponding to <B> 1.0 </B> to <B> 15 </B> parts of active chlorine, and after the reaction has ended, the new dye is obtained by evaporation.
