Description
-Verfahren zur Herstellung eines Farbstoffzwischenproduktes. Es wurde gefunden, dass ein wertvolles Farbstoffzwischenprodukt erhalten wird. wenn man 5.5'.5".5"'-Tetrahalogenkupfer- phthalocyanin-4 . 4' . 4" . 4"'=tetrasulfosäureu mit wässrigem Ammoniak erhitzt.
Die Um setzung wird zweckmässig in Gegenwart von Kupfer oder Kupfersalzen durchgeführt. An Stelle eines Cupros:alzes kann man auch die Mischung eines Cuprisalzes mit Kupfer ver wenden.
Das erhältliche Farbstoffzwischenpro- dukt ist sowohl in Säuren als auch in Alka- lien löslich, und zwar in -ersteren mit einer rotstichig blauen und in letzteren mit einer s stumpfen blaugrünen Färbung.
Es ist acy- lierbar, wobei je nach .der Natur der einge führten Acylgruppe Farbstoffe mit mehr oder minder gelbstichig grüner Nuance und ausgezeichneten Echtheitseigenschaften ent- o stehen. <I>Beispiel:
</I> Ein Gemisch von 500 Gewichtsteilen 27 % igem Ammoniak, 0,5 Gewichtsteilen Kupferbronze, 1,0 Gewichtsteilen Kupfer chlorid, 50 Gewichtsteilen der 5 .5'. 5". 5"'- 2 Tetrabromkupf erphthalocyanin - 4 . 4'. 4". 4'"- tetrasulf osäure (als Natriumsalz) wird in einem Autoklaven unter Rühren zirka 10 .Stunden auf 155-165 erhitzt. Der abge schiedene Niederschlag wird abfiltriert, in ; Wasser gelöst und von ungelösten Verunrei nigungen befreit.
Anschliessend wird das Farbstoffzwischenproduktdurch Zugabe von Kochsalz Busgesalzen.
An Stelle der oben erwähnten Tetrabrom- verbindung kann mit dem gleichen Erfolg eine äquivalente Menge der entsprechenden Tetrachlorverbindung benutzt werden.
-Process for the preparation of a dye intermediate. It has been found that a valuable intermediate dye is obtained. if one 5.5'.5 ".5" '- tetrahalocopper phthalocyanine-4. 4 '. 4 ". 4" '= tetrasulfonic acid heated with aqueous ammonia.
The implementation is expediently carried out in the presence of copper or copper salts. Instead of a cupro salt, you can also use a mixture of a cupric salt with copper.
The obtainable intermediate dye product is soluble both in acids and in alkalis, namely in the former with a reddish-tinged blue and in the latter with a dull blue-green color.
It can be acylated, and depending on the nature of the acyl group introduced, dyes with a more or less yellowish green shade and excellent fastness properties are formed. <I> example:
</I> A mixture of 500 parts by weight of 27% ammonia, 0.5 part by weight of copper bronze, 1.0 part by weight of copper chloride, 50 parts by weight of the 5 .5 '. 5 ". 5" '- 2 tetrabromo copper phthalocyanine - 4. 4 '. 4 ". 4 '" - tetrasulfonic acid (as sodium salt) is heated in an autoclave with stirring for about 10 hours to 155-165. The deposited precipitate is filtered off, in; Dissolved water and freed from undissolved impurities.
The intermediate dye product is then bus salts by adding table salt.
In place of the above-mentioned tetrabromo compound, an equivalent amount of the corresponding tetrachloro compound can be used with the same success.
