Description

  

  Verfahren zur Herstellung eines Gemisches von     Phthaloeyaninfarbstoffen.       Es wurde gefunden, dass ein wertvolles,  neues     Farbstoffgemischerhalten    wird, wenn  man das Gemisch von     Kupferphthalocyanin-          sulfonsäurechloriden,    wie es durch Einwir  ken von     Chlorsulfonsäure    auf Kupfer  phthalocyanin erhältlich ist, mit     Monoiso-          hexylamin    der Formel  
EMI0001.0008     
    zur Reaktion bringt. Der erhältliche Farb  stoff, welcher ebenfalls ein Gemisch ver  schiedener     Sulfamide    darstellt, ist in Alko  hol, Chloroform, Aceton und Chlorbenzol  leicht löslich und zeigt eine blaue Farbe.

      <I>Beispiel:</I>    10 Gewichtsteile eines Gemisches von       $upferphthalocyaninsulfochloriden,    erhalten  durch Einwirkung von     Chlorsulfonsäure    auf       Kupferphthalocyanin,    werden bei Zimmer-         temperatur    in 25 Gewichtsteilen     Monoiso-          hexylamin    der Formel  
EMI0001.0016     
         eingerührt,    wobei Erwärmung auf etwa 40'  eintritt.

   Man lässt     einige        Stunden    bei Zim  mertemperatur rühren, verdünnt dann das  Reaktionsprodukt     mit    100 Gewichtsteilen  Wasser     und        säuert    mit Salzsäure an. Der  dabei ausfallende Farbstoff wird     abfiltriert,     mit     Wasser    gewaschen und in 300 Gewichts  teilen Alkohol gelöst. Nach der Reinigung  mit Tierkohle und     Abdampfen    des Lösungs  mittels erhält man in fast quantitativer Aus  beute einen blauen, in Alkohol, Chloroform,       Aceton    und Chlorbenzol leicht löslichen  Farbstoff.



  Process for the preparation of a mixture of phthaloeyanine dyes. It has been found that a valuable, new dye mixture is obtained if the mixture of copper phthalocyanine sulfonic acid chlorides, as can be obtained by the action of chlorosulfonic acid on copper phthalocyanine, with monoisohexylamine of the formula
EMI0001.0008
    to react. The available dye, which is also a mixture of various sulfamides, is easily soluble in alcohol, chloroform, acetone and chlorobenzene and has a blue color.

      <I> Example: </I> 10 parts by weight of a mixture of copper phthalocyanine sulfochlorides, obtained by the action of chlorosulfonic acid on copper phthalocyanine, become monoisohexylamine of the formula in 25 parts by weight at room temperature
EMI0001.0016
         stirred in, heating to about 40 '.

   The mixture is stirred for a few hours at room temperature, then the reaction product is diluted with 100 parts by weight of water and acidified with hydrochloric acid. The dye which precipitates out is filtered off, washed with water and dissolved in 300 parts by weight of alcohol. After cleaning with animal charcoal and evaporation of the solvent, a blue dye which is easily soluble in alcohol, chloroform, acetone and chlorobenzene is obtained in almost quantitative yield.
