Description
Verfahren zur Herstellung eines indigoiden Farbstoffes. Es wurde .gefunden, dass man einen indi- goiden Farbstoff herstellen kann, wenn man das Acenaphthenchinon mit 7-C111.or-2,1- naphththioindoxyl kondensiert. Der Farb stoff stellt ein orangerotes Pulver dar, das sich in Schwefelsäure mit olivgrüner Farbe löst.
Er bildet eine braune Küpe und: färbt Baumwolle in orangen Tönen von sehr guten Echtheitseigeneshaften.
<I>Beispiel:</I> 182 Teile Acenaphthenchinon und 234 Teile 7-Chlor-2,1-naphththioindoxyl werden in 4000 Teilen Alkohol suspendiert und nach Zugabe von 5 Teilen konzentrierter Salzsäure zum Sieden erhitzt. Nach kurzer Zeit ist die Kondensation beendigt. Der .abgeschiedene Farbstoff wird,abfiltriert, gewaschen und ge trocknet.
Process for the production of an indigoid dye. It was found that an indigoid dye can be produced if the acenaphthenquinone is condensed with 7-C111.or-2,1-naphththioindoxyl. The dye is an orange-red powder that dissolves in sulfuric acid with an olive-green color.
It forms a brown vat and: dyes cotton in orange tones with very good fastness properties.
<I> Example: </I> 182 parts of acenaphthenquinone and 234 parts of 7-chloro-2,1-naphthioindoxyl are suspended in 4000 parts of alcohol and, after addition of 5 parts of concentrated hydrochloric acid, heated to the boil. The condensation will end after a short time. The dyestuff deposited is filtered off, washed and dried.
