  Verfahren zur Herstellung eines neuen     indigoiden        Farbstoffes.       Es wurde gefunden,     da,ss    ein     neuer,    wert  voller,     indigoider    Farbstoff entsteht, wenn  man das     1-Chlor-2,3-naphththioindoxyl    mit       Acenaphthenchinon        kondensiert.     



  Der neue Farbstoff stellt ein blaurotes  Pulver dar, das sich in     .S@chwefelsäjure    mit  grüner Farbe löst. Er     bildot    eine     orange-          braune        Küpe    und färbt Baumwolle in blau  roten Tönen von sehr guter Echtheit.  



       Beispiel:     234,5 Teile     1-Chlor-2,3-naphththioina.oxyl     und 182     Teile        Acenaphthenchinon    werden in  5000 Teilen Alkohol suspendiert und zum  Sieden erhitzt. Dann gibt man 5 Teile kon  zentrierte Salzsäure zu. Nach kurzem K0-         chen    ist die Kondensation     beendigt.    Es wird       h,eiss@    filtriert, ,gewaschen und getrocknet..



  Process for the production of a new indigoid dye. It has been found that a new, valuable, indigoid dye is formed when 1-chloro-2,3-naphththioindoxyl is condensed with acenaphthenquinone.



  The new dye is a blue-red powder that dissolves in .S @ sulfuric acid with a green color. It forms an orange-brown vat and dyes cotton in blue-red shades of very good fastness.



       Example: 234.5 parts of 1-chloro-2,3-naphththioina.oxyl and 182 parts of acenaphthenquinone are suspended in 5000 parts of alcohol and heated to the boil. Then 5 parts of concentrated hydrochloric acid are added. After a short cooking, the condensation is over. It is h, eiss @ filtered, washed and dried ..
