Description
Patentiert im Deutschen Reiche vom 27. März 1907 ab. Längste Dauer: 3.Oktober 1921.Patented in the German Empire on March 27, 1907. Longest duration: October 3, 1921.
Durch Patent 192530 ist ein Verfahren zur Darstellung blauer Schwefelfarbstoffe geschützt, welches darin besteht, daß die Arylsulfoderivate des p-Amino-p'-oxydiphenylamins mit Alkalipolysulfid behandelt werden, wonach aus dem zunächst entstehenden Produkt die Arylsulfogruppe abgespalten wird. Es wurde nun gefunden, daß man das Aminooxydiphenyiamin durch das p-Amino-m-chlorp'-oxydiphenylamin ersetzen kann; man erhält auf diese Weise ebenfalls blaue Schwefelfarbstoffe, die sich durch gute Wasch- und Lichtechtheit auszeichnen und , deren Nuance wesentlich röter als diejenige der nach dem Hauptpatent erhaltenen Produkte ist.By patent 192530 is a method for Representation of blue sulfur dyes protected, which consists in the fact that the aryl sulfoderivatives of the p-amino-p'-oxydiphenylamine are treated with alkali polysulphide, after which the aryl sulfo group is split off from the product initially formed. It has now been found that the aminooxydiphenylamine can be replaced by the p-amino-m-chlorop'-oxydiphenylamine can replace; you also get blue sulfur dyes in this way, which are characterized by good wash and lightfastness and their nuance is much redder than that of the products obtained according to the main patent.
30Teile kristallisiertes Schwefelnatrium werden mit 15 Teilen Schwefel zusammengeschmolzen und die Masse mit etwa 20 Teilen Wasser versetzt. Alsdann trägt man 10 Teile p-Toluolsulf d - p-amino - m-chlor - p'- oxydiphenylamin ein und erhitzt die Masse 48 Stunden am Rückflußkühler. Der gebildete Farbstoff wird in geeigneter Weise isoliert, beispielsweise durch Ansäuern der mit Wasser verdünnten Reaktionsmasse oder durch Ausblasen. 30 parts of crystallized sodium sulfur are melted together with 15 parts of sulfur and about 20 parts of water are added to the mass. Then you carry 10 pieces p-Toluenesulf d - p-amino - m-chloro - p'-oxydiphenylamine and heated the mass for 48 hours on the reflux condenser. The dye formed is isolated in a suitable manner, for example by acidifying the reaction mass diluted with water or by blowing out.
Zur Abspaltung der p-Toluolsulfogruppe kann man in der in dem Hauptpatent angegebenen Weise verfahren, indem man das wie oben erhaltene Produkt in konzentrierte Schwefelsäure einträgt, danach auf Eis gießt und den ausgeschiedenen Niederschlag durch Waschen mit Wasser, dem man später etwas Soda zusetzt, vollkommen von der Schwefelsäure befreit.For splitting off the p-toluenesulfo group one can proceed in the manner indicated in the main patent by adding the like The product obtained above is introduced into concentrated sulfuric acid, then poured onto ice and the deposited precipitate by washing with water, which you can later add something Soda added, completely freed from the sulfuric acid.
Die Mengenverhältnisse des Polysulfide sowie die Zeitdauer können innerhalb weiter Grenzen verändert werden.The proportions of the polysulfide as well the duration can be changed within wide limits.

Abänderung des durch Patent 192530 geschützten Verfahrens zur Darstellung blauer Schwefelfarbstoffe, dadurch gekennzeichnet, daß an Stelle der Arylsulfoderivate des p-Amino-p'-oxydiphenylatnins hier die Arylsulfoderivate des p-Aminom-chlor-p'-oxydiphenylamins verwendet werden.Modification of the method of representation protected by patent 192530 blue sulfur dyes, characterized in that instead of the aryl sulfoderivatives of p-amino-p'-oxydiphenylamine, here the arylsulfo derivatives of p-aminom-chloro-p'-oxydiphenylamine be used.
