Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 306387. Verfahren zur Herstellung eines 3'-Oxy-4'-carboxyphenylesters einer metallhaltigen Phthalocyanintetrasulfonsäure. Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Herstellung eines 3'-Oxy- 4'-earboxyphenylesters einer Kupferphthalo- cyanintetrasulfonsäure, welches dadurch ge kennzeichnet ist, dass man 1 Mol Küpfer- plithalocy anin-4,4',4",41"-tetrasulfochlorid mit.
1<B>3101</B> 1.,3-Dioxybenzol-4-earbonsätire in Gegen wart einer Mineralsäure neutralisierenden Substanz zur Umsetzung bringt.
Das zu verwendende Kupferphthalocyanin- tetrasulfochlorid kann durch Einwirkung von Chlorsulfonsäure auf Kupferphthaloeyanin- 4,4',4",4"'-tetrasulfonsäure erhalten werden.
Im nachfolgenden Beispiel bedeuten die Teile Gewichtsteile.
<I>Beispiel:</I> 29 Teile Kupferphthalocyanin-4,4',4",4"'- tet.rasulfochlorid (33/10o Mol) werden mit 200 Teilen zerkleinertem Eis vermischt und unter Rühren eine Lösung von 1.4,2 Teilen (')/,o0 Mol) 1,3-Dioxybenzol-4-carbonsäure und 7,2 Teilen Natriumhydroxyd (1001/o) in 1.50 Teilen -Wasser zugegeben.
Nach beendeter Umsetzung säuert man das Reaktionsgemisch mit Salzsäure an, trennt die ausgeschiedene Farbstoffsäure ab, löst dieselbe in Wasser und Natriumearbonat und salzt mit Natrium ehlorid aus.
Das in guter Ausbeute erhaltene Natrium salz des 3'-Oxy-4'-carboxyphenylesters der Iiupferphthaloryanin-4, 4', 4", 41"-tetrasulfon- säure stellt ein blauviolettes Pulver dar, das sich in Wasser mit tiefblauer und in k onz. Schwefelsäure mit leuchtend grüner Farbe löst. Der neue Farbstoff eignet sich zum Fär ben von Baumwolle, Viskose und Wolle. Im besonderen eignet. sich der Farbstoff im Chrom druck auf Baumwolle. Es werden kräftige, leuchtende Blautöne von vorzüglichen Nass- echtheiten und hervorragender Lichtechtheit erhalten.
Auf anodiseh oxydiertes Aluminium ge färbt, ergibt der Farbstoff ein blaustichiges Grün.
<B> Additional patent </B> to main patent no. 306387. Process for the preparation of a 3'-oxy-4'-carboxyphenyl ester of a metal-containing phthalocyanine tetrasulfonic acid. The present invention relates to a process for the preparation of a 3'-oxy-4'-earboxyphenyl ester of a copper phthalocyanine tetrasulfonic acid, which is characterized in that 1 mol of Küpfer plithalocyamine-4,4 ', 4 ", 41" - tetrasulfochloride with.
1 <B> 3101 </B> 1., 3-Dioxybenzol-4-earbonsätire in the presence of a mineral acid neutralizing substance to implement.
The copper phthalocyanine tetrasulfochloride to be used can be obtained by the action of chlorosulfonic acid on copper phthaloeyanine-4,4 ', 4 ", 4"' - tetrasulfonic acid.
In the following example, the parts are parts by weight.
<I> Example: </I> 29 parts of copper phthalocyanine-4,4 ', 4 ", 4"' - tet.rasulfochlorid (33 / 10o mol) are mixed with 200 parts of crushed ice and a solution of 1.4,2 Parts of 1,3-dioxybenzene-4-carboxylic acid and 7.2 parts of sodium hydroxide (1001 / o) in 1.50 parts of water were added.
When the reaction has ended, the reaction mixture is acidified with hydrochloric acid, the precipitated dye acid is separated off, dissolved in water and sodium carbonate and salted out with sodium chloride.
The sodium salt of the 3'-oxy-4'-carboxyphenyl ester of Iiupferphthaloryanin-4, 4 ', 4 ", 41" -tetrasulfonic acid, obtained in good yield, is a blue-violet powder that turns deep blue in water and in k onz . Sulfuric acid with a bright green color dissolves. The new dye is suitable for dyeing cotton, viscose and wool. Particularly suitable. the dye in the chrome print on cotton. Strong, luminous blue tones with excellent wet fastness and excellent light fastness are obtained.
Dyed on anodised aluminum, the dye gives a bluish green.
