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 2: 1 ein Halogenid der azogruppenhaltigen Carbonsäure der Formel
EMI0001.0006
mit '),8-1)iaminoehrysen kondensiert.
Das neue Pigment bildet ein braunes Pul ver, das sich in konz. Schwefelsäure mit vio letter Farbe löst. Es färbt. Kunststoffe, z. B. Polyvinylehloridfolien, in braunen Tönen von guter Migrations- und Lichtechtheit..
Als Säurehalogenide der obigen Zusam- rriensetzun1 kommen z. B. das Säurebromid und insbesondere das Säurechlorid in Be tracht. Diese Halogenide lassen sich zweek- mä ssig durch Behandlung der Carbonsäure der oben angegebenen Formel mit säurehalo- genierenden Mitteln wie Phosphorhalogeniden oder Phosphoroxyhalogeniden herstellen. Das Säurechlorid kann z.
B. mittels Phosphor- pentachlorid oder besonders vorteilhaft mit tels Thiony lchlorid erhalten werden. Die Be handlung mit, den säurehalogenierenden Mit teln wird zweckmässig in einem indifferenten organischen Lösungsmittel, wie Mono- oder einem Dichlorbenzol, Toluol, Xylol, Benzol oder Nitrobenzol 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 z. B. Ammoniak oder Pyridin durchzuführen. Die als Ausgangsstoffe zu verwendenden Säure chloride können aus dem Reaktionsgemisch, in welchem sie wie angegeben hergestellt wur den, abgeschieden und gegebenenfalls umkri stallisiert werden.
Man kann gegebenenfalls, insbesondere wenn zur Herstellung des Säure halogenids Thionylchlorid verwendet wurde, auf eine Abscheidung verzichten und die Kon densation unmittelbar anschliessend an die Herstellung des Säurehalogenides ausführen.
Die relative Menge der Reaktionsteilneh mer ist. so zu wählen, dass zwei Moleküle des Carbonsäurehalogenides mit einem Molekül des Diamins in Reaktion treten. Zur prakti schen Durchführung der Reaktion ist es zweck mässig, einen geringen Überschuss der erst genannten Komponente über die theoretisch erforderliche Menge anzuwenden.
Beispiel: 163 Teile des Farbstoffes, der auf übliche Weise durch Kuppeln von diazotiertem 1- Amino-3-chlorbenzol auf 2-Oxynaphthalin-3- carbonsäure erhalten wird, werden in 1800 Teilen trockenem Chlorbenzol suspendiert. Im Verlaufe von 3!4 Stunden fügt man bei 80 -unter gutem Rühren 85 Teile Thionylchlor id zu. Man hält die Reaktion eine Stunde bei 90 . Nach dem Erkalten wird das Reaktionspro dukt filtriert, mit Chlorbenzol nachgewaschen und im Vakuum bei 60 bis 70 getrocknet.
34,5 Teile dieses Säurechlorides werden in 600 Teilen wasserfreiem Chlorbenzol gelöst.. Zu dieser Lösung gibt man 12,9 Teile 2,8- Diaminochrysen, gelöst in 100 Volumteilen wasserfreiem Chlorbenzol und 5 Teilen Pyri- din, und rührt 10 Stunden bei Siedetem peratur des Lösungsmittels. Das Reaktions gemisch wird heiss abgenutscht, mit heissem Chlorbenzol und etwas Alkohol naehgewaschen und im Vakuum bei 100 getrocknet.
<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 halide of the azo group-containing carboxylic acid of the formula is used in a molecular ratio of 2: 1
EMI0001.0006
with '), 8-1) iaminoehrysen condensed.
The new pigment forms a brown powder that is in conc. Dissolves sulfuric acid with vio letter paint. It colors. Plastics, e.g. B. Polyvinyl chloride films, in brown tones with good migration and lightfastness.
The acid halides of the above composition include e.g. B. the acid bromide and especially the acid chloride in Be tracht. These halides can be prepared in two ways by treating the carboxylic acid of the formula given above with acid-halogenating agents such as phosphorus halides or phosphorus oxyhalides. The acid chloride can e.g.
B. be obtained by means of phosphorus pentachloride or particularly advantageously with thionyl chloride. The treatment with the acid-halogenating means 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, and it is recommended that this reaction be carried out at elevated temperature in the presence of an acid-binding agent such as B. ammonia or pyridine. The acid chlorides to be used as starting materials can be deposited from the reaction mixture in which they were prepared as indicated and optionally recrystallized.
If necessary, especially if thionyl chloride was used to prepare the acid halide, deposition can be dispensed with and the condensation can be carried out immediately after the preparation of the acid halide.
The relative amount of reactants is. to be chosen so that two molecules of the carboxylic acid halide react with one molecule of the diamine. To carry out the reaction in practice, it is advisable to use a small excess of the first-mentioned component over the theoretically required amount.
Example: 163 parts of the dye, which is obtained in the usual way by coupling diazotized 1-amino-3-chlorobenzene to 2-oxynaphthalene-3-carboxylic acid, are suspended in 1,800 parts of dry chlorobenzene. In the course of 3! 4 hours, 85 parts of thionylchloride are added at 80 with thorough stirring. The reaction is held at 90 for one hour. After cooling, the reaction product is filtered, washed with chlorobenzene and dried at 60 to 70 in vacuo.
34.5 parts of this acid chloride are dissolved in 600 parts of anhydrous chlorobenzene. 12.9 parts of 2,8-diaminochrysene, dissolved in 100 parts by volume of anhydrous chlorobenzene and 5 parts of pyridine, are added to this solution and the mixture is stirred for 10 hours at boiling temperature of the solvent. The reaction mixture is sucked off hot, washed with hot chlorobenzene and a little alcohol and dried in vacuo at 100.
