Description
Zusatzpatent zum Hauptpatent Nr. <B>202856.</B> Verfahren zur Herstellung eines neuen, metallhaltigen Beizenfarbstoffes. Es wurde gefunden, dass man einen neuen, chromhaltigen Beizenfarbstoff erhält,
wenn man ein Molekül 2-Amino-5-oxynaphtbalin-7- sulfonsäure zuerst in schwach saurem Medium mit einem Molekül diazotierter 2-Amino-l- oxybenzol-6-earbonsäure-4-sulfonsäure und nachher in schwach alkalischem Medium mit einem zweiten Molekül diazotierter 2-Amino- 1-oxybeiizol-6-carboiisäure-4-sulfonsäure kup pelt und den erhaltenen Disazofarbstoff mit einer ehromabgebenden Substanz behandelt.
<I>Beispiel:</I> <B>23,3</B> Teile 2-Amino-I#oxybenzol-6-earboii- säure-4-sulfotisä,ure werden wie üblich diazo- tiert und in essigsaurer Lösung mit<B>23,9</B> Teilen 2-Amino-5-oxynaphthalin-7-sulfoiisäure gekuppelt. DererhalteneMonoazofarbstoff wird i n alkalischer Lösung mit der Diazoverbindung aus 23,3 Teilen 2-Amino-l-oxybenzol-6-earbon- säure-4-sulfonsäure weitergekuppelt.
Nach be endeter Kupplung wird der erhaltene Disazo- farbstoff ausgesalzen, abgenutscht, in 2000 Teilen kochendem Wasser gelöst und die Lösung unter Zusatz von<B>50 g</B> Ameisen säure und einer Chroinacetatlösung entspre chend 30,4 Teilen Cr20s während<B>15</B> Stunden unter Rückfluss gekocht. Die neue Chromver bindung wird durch Eindampfen der Lösung in fester Form gewonnen.
Der ne-ue, chrombaltige Farbstoff bildet, wenn getrocknet, ein dunkles Pulver, löst sich in Wasser mit graustichig blauer, in konzentrierter Schwefelsäure mit violetter Farbe und liefert im Chromdruck auf Baum wolle, Kunstseide aus regenerierter Zellulose oder auf Naturseide tiefe, rotstichig graue Töne, die sich durch gute Echtheiten aus zeichnen.
Additional patent to main patent no. <B> 202856. </B> Process for the production of a new, metal-containing stain dye. It has been found that a new, chromium-containing stain dye is obtained,
if one molecule of 2-amino-5-oxynaphtbalin-7-sulfonic acid is first in a weakly acidic medium with a molecule of diazotized 2-amino-l-oxybenzene-6-carboxylic acid-4-sulfonic acid and then in a weakly alkaline medium with a second molecule of diazotized 2-Amino-1-oxybeiizole-6-carboiic acid-4-sulfonic acid kup pelt and treated the disazo dye obtained with an Ehrom-donating substance.
<I> Example: </I> <B> 23.3 </B> parts of 2-amino-I # oxybenzene-6-earboic acid-4-sulfotic acid are diazoated as usual and with acetic acid solution 23.9 parts of 2-amino-5-oxynaphthalene-7-sulfoiic acid coupled. The monoazo dye obtained is coupled further in an alkaline solution with the diazo compound composed of 23.3 parts of 2-amino-1-oxybenzene-6-carbonic acid-4-sulfonic acid.
After the coupling has ended, the disazo dye obtained is salted out, filtered off with suction, dissolved in 2000 parts of boiling water and the solution with the addition of 50 g of formic acid and a chroin acetate solution corresponding to 30.4 parts of Cr20s for a period of time Boiled under reflux for> 15 hours. The new chromium compound is obtained in solid form by evaporating the solution.
The ne-ue, chromium-containing dye forms a dark powder when dried, dissolves in water with a gray-tinged blue, in concentrated sulfuric acid with a violet color and, when printed with chrome, produces deep, red-tinged gray tones on cotton, artificial silk made from regenerated cellulose or natural silk , which are characterized by good fastness properties.
