Description
Zusatzpatent zum Hauptpatent Nr.<B>197590.</B> Verfahren zur Darstellung eines Chromierungsfarbstoffes. Gegenstand dieses Zusatzpatentes ist ein Verfahren zurDarstellung eines Ohromierungs- farbstoffes, welches dadurch gekennzeichnet ist, dass man 5-Oxybenzol-1.2.4-tricarbon- säureanhydrid mit 2.6-Dimethylchinolin kon densiert und das so erhaltene Produkt mit einem sulfierend wirkenden Mittel behandelt.
<I>Beispiel:</I> 16 Gewichtsteile 2. 6 - Dimethylebinolin, 21 Gewichtsteile 5-Oxytrimellithsäureanhy- drid und 14 Gewichtsteile Chlorzink werden bei 200-210 o C 5 Stunden verschmolzen.
Die erkaltete und pulverisierte Schmelze wird finit etwa 500 Gewichtsteilen etwa 2 %- iger Salzsäure aufgekocht, der feste Rück stand wird abgesaugt, gegen Kongopapier neutral gewaschen und getrocknet. Dann wird das so erhaltene Produkt aus siedendem, tech nischen Chinolin umkristallisiert und so als rein gelbe Substanz erhalten, die sich in kon zentrierter Schwefelsäure mit roter Farbe, in Sodalösung gelb und in verdünnter Natron lauge orangegelb löst.
Die Substanz hat fol gende Konstitution
EMI0001.0019
Die Sulfierung geschieht durch Erhitzen mit der 20fachen Gewichtsmenge 65 o/oigem Oleum auf 140 o C während ungefähr 3 Stunden. Man verdünnt mit dem gleichen Volumen konzentrierter Schwefelsäure, giesst auf 500 Teile Eis, saugt die gelbe, gelatinöse Verbin dung ab und reinigt sie durch Aussalzen aus heisser, wässriger Lösung.
Die so erhaltene Farbstoffmonosulfosäure stellt ein orangegelbes Pulver dar, das die Faser aus saurer Lösung sehr gleichmässig und leuchtend gelb färbt.
Additional patent to main patent no. <B> 197590. </B> Process for the preparation of a chromating dye. The subject of this additional patent is a process for the preparation of an odorization dye, which is characterized in that 5-oxybenzene-1,2,4-tricarboxylic anhydride is condensed with 2,6-dimethylquinoline and the product thus obtained is treated with a sulphurizing agent.
<I> Example: </I> 16 parts by weight of 2.6-dimethylbinoline, 21 parts by weight of 5-oxytrimellitic anhydride and 14 parts by weight of zinc chloride are fused at 200-210 ° C. for 5 hours.
The cooled and powdered melt is finitely boiled up to about 500 parts by weight of about 2% hydrochloric acid, the solid residue is suctioned off, washed neutral against Congo paper and dried. The product thus obtained is then recrystallized from boiling technical quinoline and thus obtained as a pure yellow substance which dissolves in concentrated sulfuric acid with a red color, yellow in soda solution and orange-yellow in dilute sodium hydroxide solution.
The substance has the following constitution
EMI0001.0019
The sulfonation takes place by heating with 20 times the weight of 65% oleum to 140 ° C. for about 3 hours. It is diluted with the same volume of concentrated sulfuric acid, poured onto 500 parts of ice, the yellow, gelatinous compound is filtered off with suction and purified by salting out a hot, aqueous solution.
The dye monosulfonic acid obtained in this way is an orange-yellow powder which colors the fibers from acidic solution very evenly and bright yellow.
