Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 297020 Verfahren zur Herstellung eines Azopigmentes Es wurde gefunden, dass man zu einem wertvollen Azopigment gelangt, wenn man im molekularen Verhältnis<B>1:</B> 2 ein Dihalogenid der azogruppenhaltigen Carbonsäure der Formel
EMI0001.0010
mit 3-Aminopyren kondensiert.
Das neue Pigment bildet ein bordeaux- farbenes Pulver, das Kunststoffe, zum Bei spiel Polyvinylchlorid, in bordeauxfarbenen Tönen von sehr guter Migrations- und Licht eehtheit färbt.
Als Säurehalogenide der obigen Zusam mensetzung kommen zum Beispiel das Dicar- bonsäuredibromid und insbesondere das Di- earbonsäuredichlorid in Betracht.
Diese Halo genide lassen sich zweckmässig durch Behand lung der Dicarbonsäure der oben angegebenen Formel mit säurehalogenierenden Mitteln, wie Phosphorhalogeniden oder Phosphoroxyhalo- geniden, herstellen. Das Säurechlorid kann zum Beispiel mittels Phosphorpentachlorid oder besonders vorteilhaft mittels Thionyl- chlorid erhalten werden.
Die Behandlung mit den säurehalogenierenden Mitteln wird zweck mässig in einem indifferenten organischen Lösungsmittel, wie Mono- oder einem Dichlor- benzol, Toluol, Xylol, Benzol oder Nitroben- zol, durchgeführt.
Die Kondensation des Säurehalogenids mit dem Diamin erfolgt vorteilhaft ebenfalls in einem der genannten organischen Lösungs mittel, wobei es zu empfehlen ist, diese Um setzung bei erhöhter Temperatur in Gegen wart eines säurebindenden Mittels, wie zum Beispiel Ammoniak oder Pyridin, durchzufüh ren. Die als Ausgangsstoffe zu verwen denden Säurechloride können aus dem Re aktionsgemisch, in welchem sie wie angegeben hergestellt wurden, abgeschieden und gege benenfalls umkristallisiert werden.
Man kann gegebenenfalls, insbesondere wenn zur Her stellung des Säurehalogenids Thionylchlorid verwendet wurde, auf eine Abscheidung ver zichten und die Kondensation unmittelbar anschliessend an die Herstellung des Säure halogenids ausführen.
Die relative Menge der Reaktionsteilneh mer ist so zu wählen, dass ein Molekül des Carbonsäurehalogenids mit zwei Molekülen des Amins in Reaktion treten. Zur prak- tischen Durchführung der Reaktion ist, es zweckmässig, einen geringen überschuss der zuletzt genannten Komponente über die theo retisch erforderliche Menge anzuwenden.
<I>Beispiel</I> 3'7 Teile des Farbstoffes, den man durch Kupplung von diazotierter 4-Chlor-3-amino- benzoesäure mit 2-Oxynaphthalin - 3 - carbon- säure erhält, werden mit<B>110</B> Volumteilen o- Dichlorbenzol versetzt.
Nach Zugabe von 28,4 Volumteilen Thionylchlorid erwärmt man das Gemisch im Bad so lange auf 13,5 bis 145 , bis ein vollständiger Übergang zu einer glitzernden Kristallsuspension stattgefunden hat, was nach 1 bis 2 Stunden der Fall ist. Dann lässt man erkalten, nutscht das Farb- stoffdicarbonsäuredichlorid ab, wäscht es mit Petroläther aus und trocknet es.
114 Teile des so erhaltenen Dichlorids werden im Gemisch mit 1'28 Teilen 3-Amino- pyren, 1600 Volumteilen Chlorbenzol und 64 Volumteilen Pyridin 22 Stunden auf 130 bis 140'D erwärmt. Dann nutscht man das gebildete Pigment heiss ab, behandelt es zur Reinigung mit heissem Chlorbenzol, heissem Alkohol und heissem Wasser und trocknet es.
<B> Additional patent </B> to main patent no. 297020 Process for the production of an azo pigment It has been found that a valuable azo pigment is obtained if a dihalide of the azo group-containing carboxylic acid is used in a molecular ratio of <B> 1: </B> 2 the formula
EMI0001.0010
condensed with 3-aminopyrene.
The new pigment forms a burgundy-colored powder that colors plastics, for example polyvinyl chloride, in burgundy shades with very good migration and lightfastness.
Suitable acid halides of the above composition are, for example, dicarboxylic acid dibromide and, in particular, dicarboxylic acid dichloride.
These halides can be conveniently prepared by treating the dicarboxylic acid of the formula given above with acid halogenating agents, such as phosphorus halides or phosphorus oxyhalides. The acid chloride can be obtained, for example, using phosphorus pentachloride or, particularly advantageously, using thionyl chloride.
The treatment with the acid-halogenating agents is expediently carried out in an inert organic solvent such as mono- or a dichlorobenzene, toluene, xylene, benzene or nitrobenzene.
The condensation of the acid halide with the diamine is also advantageously carried out in one of the organic solvents mentioned, it being advisable to carry out this reaction at an elevated temperature in the presence of an acid-binding agent such as ammonia or pyridine. The starting materials Acid chlorides to be used can be deposited from the reaction mixture in which they were prepared as indicated and, if necessary, recrystallized.
If necessary, especially if thionyl chloride was used to prepare the acid halide, there is no need for a deposition and the condensation can be carried out immediately after the preparation of the acid halide.
The relative amount of the reactants should be chosen so that one molecule of the carboxylic acid halide reacts with two molecules of the amine. To carry out the reaction in practice, it is expedient to use a small excess of the last-mentioned component over the theoretically required amount.
<I> Example </I> 3'7 parts of the dye, which is obtained by coupling diazotized 4-chloro-3-aminobenzoic acid with 2-oxynaphthalene-3-carboxylic acid, are obtained with <B> 110 </ B> parts by volume of o-dichlorobenzene added.
After adding 28.4 parts by volume of thionyl chloride, the mixture is heated to 13.5 to 145 in the bath until a complete transition to a glittering crystal suspension has taken place, which is the case after 1 to 2 hours. Then it is left to cool, the dye dicarboxylic acid dichloride is sucked off, washed out with petroleum ether and dried.
114 parts of the dichloride thus obtained are heated to 130 to 140 ° for 22 hours as a mixture with 1,28 parts of 3-aminopyrene, 1,600 parts by volume of chlorobenzene and 64 parts by volume of pyridine. The pigment is then sucked off with hot suction, treated for cleaning with hot chlorobenzene, hot alcohol and hot water and dried.
