Description
Zusatzpatent zum Hauptpatent Nr.<B>291816.</B> verfahren zur Herstellung eines neuen Farbstoffes der Phthaloeyaninreihe. Die vorliegende Erfindung bezieht sieh auf (-in Verfahren zur Herstellung eines neuen Farbstoffes der Plithalocyaninreihe, welches dadurch gekennzeichnet ist, dass Kupfer-4-p- tolylmerea.l)tophthalocyanin mit sym-Diehlor- diniethyläther zur Reaktion gebracht wird, derart,
da.ss vier Chlormethylgruppen in das Molekül eingeführt werden.
Der neue Farbstoff ist ein grüner fester Körper, der in Wasser unlöslich ist, sieh hin gegen in Schwefelsäure unter Bildung einer iin gefärbten Lösung löst.
<I>Beispiel:</I> 30 Teile grobgepulvertes, wasserfreies Alti- ininiumehlorid werden mit 7,5 Teilen Stein- kohlenteer-pyridin, das einen Siedebereich von <B>115</B> bis 1-10 C aufweist, allmählich versetzt. Die Temperatur des flüssig werdenden Ge- niisches steigt während der Zugabe auf etwa 150 C.
Man rührt das Gemisch und lässt es auf 60 C abkühlen, worauf man mit 6,5 Tei len syin-Dichlordimethyläther versetzt und da bei die Temperatur unterhalb 70 C hält. Die entstandene gelbe Schmelze wird auf 40 C gekühlt und unter Rühren bei einer Tempera tur von 40 bis 50 C portionenweise mit 5 Tei len Kupfei--tetra-4-(p-toljmereapto)-phthalo- cy anin, das durch Erhitzen von Tetra-4-ehlor- phthalocy anin mit.
p-Thiocresol und Natrium liy droxy d in Benzylalkohol erhalten -werden kann, versetzt.. Die Flüssigkeit wird während 30 Minuten bei 50 C erhitzt und hierauf in 300 Teile Wasser gegeben. Die so erhaltene grüne Suspension wird filtriert. Der grüne feste Rückstand wird mittels Wasser säurefrei ge waschen und schliesslich zweimal mit Alkohol gewaschen. Das Produkt. wird bei 60 C ge trocknet. Man erhält auf diese Weise 5,85 Teile eines grünen Pulvers, das aus Kupfer tetra- (chlormethyl)-tetra-(p-tolylmercapto)- phthalocyanin besteht.
Additional patent to main patent no. <B> 291816. </B> Process for the production of a new dye of the phthaloeyanine series. The present invention relates to (-in a process for the preparation of a new dye of the plithalocyanine series, which is characterized in that copper-4-p-tolylmerea.l) tophthalocyanine is reacted with sym-diehlor- diniethyl ether in such a way,
da.ss four chloromethyl groups are introduced into the molecule.
The new dye is a green solid which is insoluble in water, but dissolves in sulfuric acid to form a colored solution.
<I> Example: </I> 30 parts of coarsely powdered, anhydrous altinium chloride are gradually mixed with 7.5 parts of coal tar pyridine, which has a boiling range of <B> 115 </B> to 1-10 ° C . The temperature of the liquid mixture rises to about 150 C during the addition.
The mixture is stirred and allowed to cool to 60 ° C., whereupon 6.5 parts of syin dichlorodimethyl ether are added and the temperature is kept below 70 ° C. The resulting yellow melt is cooled to 40 C and, while stirring, at a temperature of 40 to 50 C in portions with 5 parts of copper tetra-4- (p-toljmereapto) -phthalocyanine, which is obtained by heating tetra- 4-chlorophthalocyanine with.
p-Thiocresol and sodium liy droxy d in benzyl alcohol can be obtained. The liquid is heated for 30 minutes at 50 C and then poured into 300 parts of water. The green suspension thus obtained is filtered. The green solid residue is washed free of acid using water and then washed twice with alcohol. The product. is dried at 60 C. In this way, 5.85 parts of a green powder consisting of copper tetra- (chloromethyl) -tetra- (p-tolylmercapto) -phthalocyanine are obtained.
