Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 118232. Verfahren zur Herstellung eines neuen indigoiden Farbstoffes. Es wurde gefunden, dass man einen neuen indigoiden Farbstoff erhält, wenn man in einer ersten Phase das 6-Chlor-o-toluidin <B>(CM:</B> NH2 :
Cl = 1 : 2 : 6) durch Diazotieren, Vereinigen der Diazoverbindung mit einem Alkalixanthogenat,Behandlung des Kupplungs produktes mit einem Ätzalkali und Konden sation der entstandenen Verbindung mit einem Alkalisalz einer Monohalogenessigsäure, in die 2-i#lethyl-3-chlor-l-pheny-lthioglykolsäure überführt,
in einer zweiten Phase diese durch Behandeln mit kondensierend wirkenden Mit teln zum 6-Chlor-7-methyl-3-oxythionaphten cyclisiert und in einer dritten Phase 1 Mol. 6-Chlor-7-methyl-3-oxythionaphten, 1 Mol. 1-Chlor-2,3-naphthooxythiophen und 1 Mol. einer aromatischen Nitrosoverbindung aufein ander einwirken lässt, und zwar derart, dass man die Nitrosoverbindung mit einer der Komponenten reagieren lässt und das so er haltene Anil mit der andern Komponente kondensiert.
Der neue Farbstoff bildet ein violettes Pulver, das sich in Schwefelsäure mit grüner Farbe auflöst. Er färbt Baumwolle aus orangefarbener güpe in sehr echten, violetten Tönen. <I>Beispiel:</I> 71. Teile 6-Chlor-o-toluidin (CHa : NH2 : Cl <B>=1:2:6)</B> werden in bekannter Weise dia- zotiert -und in eine<B>701'</B> heisse Lösung von 90 Teilen xanthogensaurem Kali und 80 Teilen Soda eingetragen.
Ist die Gasent wicklung beendet, so wird erkalten ge lassen, ausgeäthert, nach dem Abdunsten des Äthers mit 125 Teilen Natronlauge ä 40 Bd und 300 Teilen Sprit am Rückflusskühler ver seift und in derselben Lösung mit 70 Teilen Chloressigsäure, gelöst in 84 Teilen Natron lauge ä 4011 Be und Wasser, kondensiert. Den Sprit destilliert man ab, lässt erkalten und säuert mit Salzsäure an. Die ausgeschie dene 2-Methyl-3-chlorphenylthioglykolsäure wird filtriert und getrocknet. Aus verdünntem Sprit umkristallisiert, bildet sie weisse Nadeln vom Schmelzpunkt 10411.
28 Teile dieses Produktes werden nun in der zehnfachen Menge Phosphortrichlorid ge löst; alsdann setzt man 22 Teile Aluminium chlorid zu und erwärmt langsam auf 60 bis 65 . Unter lebhafter Chlorwasserstoffentwick- lung nimmt die Flüssigkeit eine rotbraune Farbe an. Der Überschuss des Phosphortri- chlorids wird nun im Vakuum abdestilliert und der Rückstand in Wasser und Eis aus getragen zur Zersetzung der Phosphor- und Aluminiumverbindungen. Man filtriert und reinigt das Reaktionsprodukt durch Lösen in verdünnter Lauge, Filtrieren und Fällen mit Säure.
Das 6-Chloi--7-methyl-3-oxythioriaphten bildet einen farblosen Körper, der aus ver dünnter Essigsäure in schönen Nadeln vorn Schmelzpunkt 102 bis<B>103'</B> kristallisiert. In Alkohol, Äther, Ligroin, Benzol ist er schwer löslich; durch Destillation mit Wasserdampf kann er leicht in reinem Zustande erhalten werden.
19,8 Teile 6 - Chlor- 7-methyl - 3 - oxythio- naphten werden in 100 Teilen 12 /oiger Na tronlauge gelöst, auf 40-50 o erhitzt und mit einer Lösung von 16,5 Teilen p-Nitro- sodimethylanilin in 100 Teilen Sprit versetzt. Sofort tritt Kondensation ein und der aus fallende dicke Brei wird filtriert und solange mit heissem Wasser ausgewaschen, bis das Filtrat farblos abläuft.
Das neue p-Dimethyl- aminoanil des 6-Chlor-7-methyl-thionaphten- chinons löst sich in heissem Benzol mit roter Farbe und kristallisiert beim Erkalten in schönen grünglänzenden Nadeln vom Schmelz punkt 256-257 0.
330 Teile dieses Anils werden nun mit 234,6 Teilen 1-Chlor-2,3-naphthooxythiopheri in 4000 Teilen Alkohol suspendiert und zum Sieden erhitzt. Nach einigen Stunden ist die Kondensation beendet. Der abgeschiedene Farbstoff wird filtriert, gewaschen und ge trocknet.
<B> Additional patent </B> to main patent No. 118232. Process for the production of a new indigoid dye. It has been found that a new indigoid dye is obtained if 6-chloro-o-toluidine <B> (CM: </B> NH2:
Cl = 1: 2: 6) by diazotizing, combining the diazo compound with an alkali metal oxanthate, treating the coupling product with a caustic alkali and condensing the resulting compound with an alkali salt of a monohaloacetic acid into the 2-i # ethyl-3-chloro-1 -pheny-lthioglycolic acid transferred,
in a second phase this cyclized by treatment with condensing means to 6-chloro-7-methyl-3-oxythionaphten and in a third phase 1 mol. 6-chloro-7-methyl-3-oxythionaphten, 1 mol. 1- Chlor-2,3-naphthooxythiophene and 1 mole of an aromatic nitroso compound can act on one another in such a way that the nitroso compound is allowed to react with one of the components and the anil thus obtained is condensed with the other component.
The new dye forms a purple powder that dissolves in sulfuric acid with a green color. He dyes cotton from orange güpe in very real, purple tones. <I> Example: </I> 71. Parts of 6-chloro-o-toluidine (CHa: NH2: Cl <B> = 1: 2: 6) </B> are diazotized in a known manner - and into a <B> 701 '</B> hot solution of 90 parts of xanthogenic potash and 80 parts of soda.
When the evolution of gas has ended, it is allowed to cool down, extracted with ether, after evaporation of the ether is soaped with 125 parts of 40 Bd caustic soda and 300 parts of fuel on the reflux condenser and in the same solution with 70 parts of chloroacetic acid, dissolved in 84 parts of caustic soda 4011 Be and water, condensed. The fuel is distilled off, allowed to cool and acidified with hydrochloric acid. The precipitated 2-methyl-3-chlorophenylthioglycolic acid is filtered and dried. Recrystallized from dilute fuel, it forms white needles with a melting point of 10411.
28 parts of this product are now dissolved in ten times the amount of phosphorus trichloride; 22 parts of aluminum chloride are then added and the mixture is slowly heated to 60 to 65. With vigorous evolution of hydrogen chloride, the liquid takes on a red-brown color. The excess phosphorus trichloride is then distilled off in vacuo and the residue is carried out in water and ice to decompose the phosphorus and aluminum compounds. The reaction product is filtered and purified by dissolving it in dilute alkali, filtering and precipitating with acid.
The 6-Chloi - 7-methyl-3-oxythioriaphten forms a colorless body, which crystallizes from dilute acetic acid in beautiful needles with a melting point of 102 to 103 '. It is sparingly soluble in alcohol, ether, ligroin, and benzene; it can easily be obtained in a pure state by distillation with steam.
19.8 parts of 6 - chloro-7-methyl - 3 - oxythio- naphten are dissolved in 100 parts of 12 / oiger sodium hydroxide solution, heated to 40-50 o and with a solution of 16.5 parts of p-nitro-sodimethylaniline in 100 Share fuel. Immediately condensation occurs and the thick pulp that falls is filtered and washed out with hot water until the filtrate runs colorless.
The new p-dimethylaminoanil of 6-chloro-7-methyl-thionaphtenquinone dissolves in hot benzene with a red color and crystallizes in beautiful green, shiny needles with a melting point of 256-257 0 on cooling.
330 parts of this anil are then suspended with 234.6 parts of 1-chloro-2,3-naphthooxythiopheri in 4000 parts of alcohol and heated to the boil. After a few hours, the condensation has ended. The deposited dye is filtered, washed and dried.
