Description
Zusatzpatent zum Hauptpatent Nr. 297020. Verfahren zur Herstellung eines Azopigmentes. Es wurde gefunden, dass man zu einem wert vollen Azopigment gelangt., wenn man im mole kularen Verhältnis 2:1 ein Halogenid der azogruppenhaltigen Carbonsäure der Formel
EMI0001.0008
mit 1,5-Diaminonaphthalin kondensiert.
Das neue Pigment färbt Kunststoffe, z. B. Polyvinylehlorid, in gelbstichig orangen Tönen von sehr guter Echtheit.
Als Säurehalogenide der obigen Zusammen setzung kommen z. B. das Säurebromid und insbesondere das Säurechlorid in Betracht. Diese Halogenide lassen sich zweckmässig durch Behandlung der Carbonsäure der oben a j, "ebenen Formel mit säurehalogenierenden Mitteln wie Phosphorhalogeniden oder Phos- phoroxyhalogeniden herstellen. Das Säure chlorid kann z.
B. mittels Phosphorpenta- ehlorid oder besonders vorteilhaft mittels Thio- nylchlorid erhalten werden. Die Behandlung mit den säurehalogenierenden Mitteln wird zweckmässig in einem indifferenten organi- sehen Lösungsmittel wie Mono- oder einem Dichlorbenzol, Toluol, Xylol, Benzol oder Nitrobenzol durchgeführt.
Die Kondensation des Säurehalogenides 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 Gegenwart eines säurebindenden Mittels wie z. B. Ammo niak oder Pyridin durchzuführen. Die als Ausgangsstoffe zu verwendenden Säurechlo ride können aus dem Reaktionsgemisch, in welchem sie wie angegeben hergestellt wurden, abgeschieden und gegebenenfalls umkristalli siert werden.
Man kann gegebenenfalls, ins besondere wenn zur Herstellung des Säure halogenides 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 praktischen Durchführung der Reaktion ist es zweckmässig, einen geringen überschuss der erstgenannten Komponente über die theoretisch erforderliche Menge anzuwenden.
<I>Beispiel:</I> 45,2 Teile des Farbstoffes aus diazotiertem 1- Amino-5-trifluormethylbenzol-2-äthylsulfon und 2,3-Oxynaphthoesäure werden in 500 Vo- lumteilen wasserfreiem Toluol angerührt- und mit 28,6 Teilen Thionylchlorid versetzt und zum Sieden erhitzt. Nach dem Eintreten voll ständiger Lösung wird noch eine halbe Stunde im Sieden gehalten, heiss klärfiltriert und das Filtrat einige Zeit stehengelassen. Die ab filtrierten Kristalle wäscht man auf der Nutsche nach und trocknet sie im Vakuum bei 45 .
47 Teile dieses Säurechlorides werden in 500 Volumteilen trockenem Toluol heiss ge löst. In diese Lösung lässt man rasch 7,9 Teile 1,5-Diaminonaphthalin, gelöst in 200 Volum- teilen trockenem Toluol und 30 Volumteilen trockenem Pyridin einlaufen. Die Farbstoff bildung wird durch etwa 15stündiges Sieden am Rückfluss beendet. Man filtriert heiss ab und wäscht das Nutsehgut mit heissem Toluol gründlich nach und trocknet.
Additional patent 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
EMI0001.0008
condensed with 1,5-diaminonaphthalene.
The new pigment colors plastics, e.g. B. Polyvinyl chloride, in yellowish orange tones of very good fastness.
As acid halides of the above composition come z. B. the acid bromide and especially the acid chloride into consideration. These halides can be conveniently prepared by treating the carboxylic acid of the above a j, "flat formula with acid halogenating agents such as phosphorus halides or phosphorus oxyhalides. The acid chloride can, for.
B. by means of phosphorus pentahloride or particularly advantageously by means of 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, 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 and optionally recrystallized from the reaction mixture in which they were prepared as indicated.
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 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 slight excess of the first-mentioned component over the theoretically required amount.
<I> Example: </I> 45.2 parts of the dye from diazotized 1-amino-5-trifluoromethylbenzene-2-ethylsulfone and 2,3-oxynaphthoic acid are mixed in 500 parts by volume of anhydrous toluene and mixed with 28.6 parts Thionyl chloride added and heated to boiling. After the complete solution has entered, the mixture is kept at the boil for half an hour, clarified by filtration while hot and the filtrate is left to stand for some time. The crystals filtered off are washed on the suction filter and dried in vacuo at 45.
47 parts of this acid chloride are dissolved in 500 parts by volume of dry toluene hot. 7.9 parts of 1,5-diaminonaphthalene, dissolved in 200 parts by volume of dry toluene and 30 parts by volume of dry pyridine, are rapidly run into this solution. The formation of the dye is ended by refluxing for about 15 hours. It is filtered off while hot and the Nutsehgut is washed thoroughly with hot toluene and dried.
