Description

  

  Verfahren zur Herstellung eines neuen     indigoiden        Farbstoffes.       Es wurde gefunden, dass man einen neuen       indigoiden    Farbstoff erhält, wenn man das       1.-Chlro-2.3-tliionaphthisatin,    welches erhal  ten werden kann durch Kondensieren von       1-Chlor-2-thionaphthol    mit     Oxalylchlorid,     mit     Oxythionaphthenkarbonsäüre    konden  siert.  



  Der neue Farbstoff bildet ein violett  rotes Pulver, löst sich in konzentrierter  Schwefelsäure mit     olivegrüner    Farbe und  gibt mit     Hydrosulfit    und Natronlauge eine  gelbe     Küpe,    aus welcher Baumwolle in blau  violetten Farbtönen gefärbt wird, die beim  Seifen röter und reiner werden. Diese Fär  bungen sind sehr licht-, wasch-,     bäuch-    und  chlorecht.  



  <I>Beispiel:</I>  In 10000 Teile Alkohol werden 248,5 Teile       1-Chlor-2    .     3-thionaphthisatin    und 194 Teile       Oxyfhionaphtenkarbonsäure    eingetragen und  hierauf längere Zeit am     Rückflusskühler    ge-    kocht. Der gebildete Farbstoff wird filtriert;  gewaschen und getrocknet.



  Process for the production of a new indigoid dye. It has been found that a new indigoid dye is obtained if the 1.-chloro-2,3-tliionaphthisatin, which can be obtained by condensing 1-chloro-2-thionaphthol with oxalyl chloride, is condensed with oxythionaphthene carboxylic acid.



  The new dye forms a violet-red powder, dissolves in concentrated sulfuric acid with an olive-green color and, with hydrosulfite and sodium hydroxide solution, gives a yellow vat from which cotton is dyed in blue-violet hues, which become redder and purer when soapy. These colors are very light, wash, tummy and chlorine-proof.



  <I> Example: </I> In 10,000 parts of alcohol there are 248.5 parts of 1-chloro-2. 3-thionaphthisatin and 194 parts of Oxyfhionaphtenkarbonsäure entered and then boiled for a long time on the reflux condenser. The dye formed is filtered; washed and dried.
