Description

Verfahren zur Umwandlung von rohen Polyhalogenkupferphthalocyaninen in eine Pigmentform 2. Zusatz zu Patent , ... ... (Patentanmeldung B 83 947 IVc/8m) Gegenstand der Patents . ... ... (Patentanmeldung B 83 ]47 IVc/vm) ist ein Verfahren zur Umwandlung roher Polyhalogenkupferphthalocyanine in hochwertige Pigmente, bei dem man den Rohfarbstoff mit Schwefelsäure und einer organischen Flüssigkeit in Gegenwart von 0,2 bis 2, vorzugsweise 0,5 bis 1,5 Gewichtsteilen Nitrosylschwefelsäure, bezogen auf 1 Gewichtsteil Farbstoff, behandelt.Process for converting crude polyhalogen copper phthalocyanines into a pigment form 2. Addition to patent, ... ... (Patent application B 83 947 IVc / 8m) Subject matter of the patents. ... ... (patent application B 83 ] 47 IVc / vm) is a process for converting crude polyhalogen copper phthalocyanines into high-quality pigments, in which the crude dye is treated with sulfuric acid and an organic liquid in the presence of 0.2 to 2, preferably 5 to 1.5 parts by weight of nitrosylsulfuric acid, based on 1 part by weight of dye, treated.

Es wurde nun gefunden, daß man rohe Polyhalogenkupferphthalocyanine ebenfalls auf vorteilhafte Weise in Pigmente umwandeln kann, wenn man den Rohfarbstoff mit Schwefelsäure und einer organischen Flüs-. sigkeit in Gegenwart von 0;1 his 0,2 Gewichtsteilen Nitrosylschwefelsäure, bezogen auf 1 Gewichtsteil Farbstoff, behandelt.It has now been found that crude polyhalocopper phthalocyanines can also be converted into pigments in an advantageous manner if you use the raw dye with sulfuric acid and an organic hydrofluoric. sigkeit in the presence of 0; 1 his 0.2 part by weight of nitrosylsulfuric acid, based on 1 part by weight of dye, treated.

Fär das Verfahren dieses Zusatzpatents gelten im übrigen die Angaben des Hauptpatents.For the procedure of this additional patent, the information applies of the main patent.

Beispiel 20 Teile (hier wie im folgenden Gewichtsteile) Hexadecachlorkupferphtrialocyanin werden in 200 Teilen Trichlorbenzol suspendiert und auf 110 °C erwärmt. Im Verlauf von ungefähr 30 Minuten läßt man bei guter Rührung eine Mischung von 25 Teilen konzentrierter Schwefelsäure und 3 Teilen Nitrosylschwefelsäure zulaufen und hält die Mischung noch eine Stunde bei 110 oC. Man kühlt auf Raumtemperatur, gibt Wasser zu, saugt das Pigment ab und wäscht mit Dimethylformamid und Wasser aus.Example 20 parts (here as in the following parts by weight) of hexadecachlorocopper phtrialocyanine are suspended in 200 parts of trichlorobenzene and to 110 ° C warmed up. Allow to mix for about 30 minutes with good agitation run in from 25 parts of concentrated sulfuric acid and 3 parts of nitrosylsulfuric acid and keep the mixture at 110 oC for another hour. One cools to room temperature, adds water, sucks off the pigment and washes with dimethylformamide and water the end.

Man erhält 18 Teile eines gelbstichigen Grünpigments mit sehr guter Farbstärke und Farbreinheit.18 parts of a yellowish green pigment with very good Color strength and color purity.
