Description
Zusatzpatent 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<B>1:</B> 2 ein Dihalogenid der azogruppenhaltigen Carbonsäure der Formel
EMI0001.0008
mit 4-Amino-1,1'-diphenyl kondensiert.
Das neue Pigment bildet ein leuchtend rotes, weichkörniges Pulver, das Kunststoffe, zum Beispiel Polyvinylchlorid, in blaustichig roten Tönen von sehr guter Migrations- und l.iehtechtheit färbt.
Als Säurehalogenide der obigen Zusam mensetzung kommen zum Beispiel das Di- earbonsäuredibromid und insbesondere das Dicarbonsäuredichlorid in Betracht. Diese Halogenide lassen sich zweckmässig durch Behandlung der Dicarbonsäure der oben an gegebenen Formel mit säurehalogenierenden Mitteln, wie Phosphorhalogeniden oder Phos- phoroxyhalogeniden, herstellen.
Das Säure- chlorid kann zum Beispiel mittels Phosphö =" pentachlorid oder besonders vorteilhaft mit tels Thionylchlorid 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 zum Beispiel Ammoniak oder Pyridin, durchzu führen. Die als Ausgangsstoffe zu verwen denden Säurechloride können aus dem Reak tionsgemisch, 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 an schliessend 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 praktischen Durchführung der Reaktion ist es zweck- mässig, einen geringen Überschuss der zuletzt genannten Komponente über die theoretisch erforderliche Menge anzuwenden.
<I>Beispiel</I> 37 Teile des Farbstoffes, den man durch Kupplung von diazotierter 4-Chlor-3-amino- benzoesäure mit 2-Oxynaphthalin - 3 - carbon- säure erhält, werden mit 110 Volumteilen o- Dichlorbenzol versetzt.
Nach Zugabe von 28,4 Volumteilen Thionylchlorid erwärmt man das Gemisch im Bad so lange auf 13'5 bis l45 , bis ein vollständiger Übergang zu einer glit zernden Kristallsuspension stattgefunden hat, was nach 1 bis 2. Stunden der Fall ist. Dann lässt man erkalten, nutscht das Farbstoff- dicarbonsäuredichlorid ab, wäscht es mit Pe- troläther aus und trocknet es.
36 Teile des so erhaltenen Dichlorids werden im Gemisch mit 31,3 Teilen 4-Amino- 1,1'-diphenyl, 500 Volumteilen Nitrobenzol und 16 Volumteilen Pyr idin 16 Stunden auf 130 bis 140 erwärmt. Dann nutscht man das gebildete Pigment noch heiss ab, behandelt es zur Reinigung mit heissem Chlorbenzol, heissem Alkohol, heissem Wasser und trock net es.
Additional patent 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 dihalide of the azo group-containing carboxylic acid is used in a molecular ratio of <B> 1: </B> 2 the formula
EMI0001.0008
condensed with 4-amino-1,1'-diphenyl.
The new pigment forms a bright red, soft-grain powder that colors plastics, e.g. polyvinyl chloride, in bluish red tones with very good migration and oil fastness.
Suitable acid halides of the above composition are, for example, dicarboxylic acid dibromide and, in particular, dicarboxylic acid dichloride. These halides can conveniently be 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, by means of phosphorus pentachloride or, particularly advantageously, by means of thionyl chloride. The treatment with the acid-halogenating agents is expediently in an inert organic solvent such as mono- or 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 acid chlorides to be used as starting materials 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, deposition can be dispensed with 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 advisable to use a small excess of the last-mentioned component over the theoretically required amount.
<I> Example </I> 37 parts of the dye obtained by coupling diazotized 4-chloro-3-aminobenzoic acid with 2-oxynaphthalene-3-carboxylic acid are mixed with 110 parts by volume of o-dichlorobenzene.
After adding 28.4 parts by volume of thionyl chloride, the mixture is heated in the bath to 13.5 to 145 until a complete transition to a glit-ting 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.
36 parts of the dichloride thus obtained are heated to 130 to 140 in a mixture with 31.3 parts of 4-amino-1,1'-diphenyl, 500 parts by volume of nitrobenzene and 16 parts by volume of pyridine in 16 hours. The pigment formed is then sucked off while it is still hot, treated for cleaning with hot chlorobenzene, hot alcohol, hot water and dried.
