Verfahren zur Darstellung neuer KOpenfarb8toft'e.
Ei wurde gefunden, dass man zu wertvollen Küpenfarbstoffen gelangt, wenn man die Kondensationsprodukte aus Azenaphtenchinon oder dessen Substitutionsprodukten mit 6-Amido- -3-oxy-(1)-thionaphten-2-karbonsäuren bzw. 6-Amino-3-oxy-(1)-thionaphtenen der Halogenierung unterwirft. Die so erhältlichen Farbstoffe färben aus alkalischer Küpe sowohl Baumwolle als auch Wolle orange bis bräunlich-orange.

Sodann erwärmt man noch ein bis zwei Stunden auf 200 bis 220 C, lässt erkalten und filtriert das ausgeschiedene Bromieruugsprodukt ab. Der neue Farbstoff wir (i in Form eines braungelbon Pulvers erhalten, das sich in konzentrierter Schwefelsäure mit grünlich-blauer Farbe löst.

Procedure for displaying new KOpenfarb8toft'e.
It has been found that valuable vat dyes can be obtained if the condensation products of azenaphthenequinone or its substitution products with 6-amido- -3-oxy- (1) -thionaphten-2-carboxylic acids or 6-amino-3-oxy- ( 1) -thionaphtenes subject to halogenation. The dyes obtainable in this way dye both cotton and wool from an alkaline vat from orange to brownish-orange.
Example 1.
A mixture, cooled to 0 ° C., of 80 parts of sulfuric acid 1970/0 and 7 parts of bromine is obtained, with thorough stirring, by condensing azenaphtenquinone with 6-amino-3-oxy- (1) -thionaphthene in alcohol
EMI1.1
have a lively orange shade.
Example 2.
3 # 7 parts of the by condensation of 6-amino-3-oxy-1-thionaphtenecarboxylic acid with
EMI1.2
3r) suspended up to 40 parts of nitrobenzene, added 7 parts of bromine, whereupon the mixture is stirred for twelve hours at ordinary temperature. The mixture is then heated to 200 to 220 ° C. for one to two hours, allowed to cool and the precipitated bromination product is filtered off. The new dye is obtained in the form of a brownish-yellow powder that dissolves in concentrated sulfuric acid with a greenish-blue color.
Its vat colors have a brownish-orange shade.
The representation of dyes takes place in an analogous manner using
EMI1.3
A minoazenaphthene quinone.
