Description
<B>Zusatzpatent</B> zum Hauptpatent Nr.<B>297020</B> 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
EMI0001.0008
mit 3,3-Dimethyl - 4,4' - diaminodiphenyl kon densiert.
Das neue Pigment färbt Kunststoffe, zum Beispiel Polyv inylchlorid, in gelbroten Tönen von sehr guter Migrations- und Lichtechtheit.
Als Säurehalogenide der obigen Zusam mensetzung kommen zum Beispiel das Säure bromid und insbesondere das Säurechlorid in Betracht. Diese Halogenide lassen sich zweck mässig durch Behandlung der Carbonsäure der oben angegebenen Formel mit säurehalo- genierenden Mitteln, wie Phosphorhalogeni- den oder Phosphoroxyhalogeniden, herstellen. Das Säurechlorid kann zum Beispiel mittels Phosphorpentachlorid oder besonders vorteil haft mittels Thionylchlorid erhalten werden.
Die Behandlung mit den säurehalogenieren- den Mitteln wird zweckmässig in einem in differenten organischen Lösungsmittel, wie: Mono- oder o-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 durchzufüh ren. Die als Ausgangsstoffe zu verwendenden Säurechloride können entweder 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 zwei Moleküle des Carbonsäurehalogenids mit einem Molekül des Diamins in Reaktion treten. Zur prak tischen Durchführung der Reaktion ist es zweckmässig, einen geringen Überschuss der erstgenannten Komponente über die theore tisch erforderliche Menge anzuwenden.
<I>Beispiel</I> 76 Teile trockenes, salzhaltiges Farb- stoffpulver, enthaltend '53,3 Teile des Farb stoffes, den man durch Kupplung von diazo- tierter 2 - Amino-1,1'-diphenyläther-4-carbon- säure mit 2-Oxynaphthalin-3-carbonsäure-2'- methoxyanilid erhält, werden in 800 Volum- teilen Chlorbenzol vorgelegt. Aus dem Ge misch werden zur vollständigen Entwässe rung 30 Volumteile Flüssigkeit herausdestil liert.
Nach dem Erkalten gibt man<B>21,3</B> Vo- lumteile Thionylchlorid zu und erwärmt das Gemisch für die Dauer von 3 Stunden auf eine Badtemperatur von 125 bis 135 . Dann rührt man kalt, nutscht das kristallisierte Farbstoffearbonsäurechlorid, wäscht mit Pe- troläther und trocknet es.
66 Teile des so erhaltenen Chlorids wer den im Gemisch mit 10g6 Teilen 3,3'-Di- methyl-4,4'-diamino-1,1'-diphenyl, 900 Volum- teilen Chlorbenzol und 12 Volumteilen Pyri- din während 16 Stunden auf 1'30 bis 140 erwärmt. Dann nutseht man das gebildete Pigment noch heiss ab und behandelt es zur Reinigung mit heissem Chlorbenzol, heissem Alkohol und schliesslich heissem Wasser.
<B> Additional patent </B> to main patent no. <B> 297020 </B> 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 is used in a molecular ratio of 2: 1 the formula
EMI0001.0008
condensed with 3,3-dimethyl-4,4'-diaminodiphenyl.
The new pigment colors plastics, for example polyvinyl chloride, in yellow-red shades with very good migration and lightfastness.
Suitable acid halides of the above composition are, for example, acid bromide and especially acid chloride. These halides can be conveniently prepared 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 be obtained, for example, by means of phosphorus pentachloride or particularly advantageously by means of thionyl chloride.
The treatment with the acid-halogenating agents is expediently carried out in a different organic solvent, such as: mono- or o-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 conversion be carried out at elevated temperature. The acid chlorides to be used as starting materials can either be taken from the reaction mixture in which they are like specified were prepared, deposited 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 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 amount theoretically required.
<I> Example </I> 76 parts of dry, salt-containing dye powder, containing 53.3 parts of the dye obtained by coupling diazotized 2-amino-1,1'-diphenyl ether-4-carbon acid obtained with 2-oxynaphthalene-3-carboxylic acid-2'-methoxyanilide are introduced into 800 parts by volume of chlorobenzene. 30 parts by volume of liquid are distilled out of the mixture for complete drainage.
After cooling, <B> 21.3 </B> parts by volume of thionyl chloride are added and the mixture is heated to a bath temperature of 125 to 135 for a period of 3 hours. The mixture is then stirred cold, the crystallized dyestuff carbonyl chloride is suction filtered, washed with petroleum ether and dried.
66 parts of the chloride thus obtained are mixed with 10 g6 parts of 3,3'-dimethyl-4,4'-diamino-1,1'-diphenyl, 900 parts by volume of chlorobenzene and 12 parts by volume of pyridine for 16 hours heated to 1'30 to 140. The pigment formed is then removed while it is still hot and treated for cleaning with hot chlorobenzene, hot alcohol and finally hot water.
