Description
Procédé de préparation de 2,6-bis (8'-benzoylamino-anthraquinonylamino-l')-anthraquinone. Le présent brevet a pour objet un procédé de préparation de 2,6-bis(8'-benzoylamino- anthraquinonylamino-1') -anthraquinone, un composé connu de formule:
EMI0001.0005
Ce procédé est caractérisé en ce qu'on fait réagir une 1-halogéno-8-benzoylamino-anthra- quinone avec de la 2,6-diaminoanthraqüinone en présence d'une substance capable de se combiner avec les acides, en quantité suffi sante pour .réagir avec l'acide halogènehydri- que mis en liberté, et en présence d'un cata lyseur cuprifère contenant du cuivre et de l'iode dans un rapport de 0,9 à 2,0 atomes d'iode pour un atome de cuivre. De préfé rence, on opère en présence d'un catalyseur cuprifère contenant 1,1 à 1,8 atome d'iode par atome de cuivre.
Les catalyseurs cuprifères contenant du cuivre et de l'iode dans le rapport indiqué ci-dessus sont très efficaces dans la présente réaction et permettent d'obtenir un produit pratiquement exempt d'impuretés, ce qui re présente un progrès industriel important.
Le rendement du procédé diminue brus quement quand on approche de la limite supé rieure de 2 atomes d'iode par atome de cuivre dans le catalyseur. Si l'on utilisait plus de 2 atomes d'iode, l'excès se retrouverait par tiellement sous forme d'iode libre, provoquant une diminution encore plus marquée du ren dement. En général, l'intervalle compris entre un peu moins d'un atome et environ 1 atome 1/. d'iode par atome de cuivre représente l'inter valle optimum, bien que celui-ci puisse varier quelque peu suivant la nature des réactifs.
Comme substance capable de se combiner avec les acides, on peut utiliser l'une quel- conque des substances connues qui sont utili sées ordinairement dans ce but.
La quantité de catalyseur n'est pas déter minante. D'une manière générale, une quan tité d'environ <B>0,1</B> atome de cuivre par molé- cide de diaminoanthraqtûnone représente la limite inférieure pratique. Il est bien possible que le catalyseur entre réellement en réac tion et soit . régénéré de façon continue, de sorte que son action tiendrait davantage de celle d'un agent de condensation que de celle d'un catalyseur proprement dit.
Des quan tités excessives de catalyseur entraînent sim plement un gaspillage de cuivre et d'iode et en général on obtient les résultats optimum dans l'intervalle de 0,1 à 1,0 atome de cuivre par molécule de diaminoanthraquinone.
La réaction peut être effectuée en pré sence d'un solvant. La nature de ce solvant n'est pas déterminante. Les solvants inertes ordinairement utilisés dans les autres réac tions d'Ullmann conviennent bien. Ils doivent naturellement être inertes dans les conditions de la réaction, même aux températures éle vées de 150-250 C qui sont susceptibles d'être atteintes. Le solvant préféré est le nitrobenzène. Il est également possible d'opé rer sans aucun solvant, mais, pour la facilité de la manipulation mécanique, il est dési rable d'utiliser un solvant ou diluant.
L'exemple suivant, dans lequel les parties sont exprimées en poids, montre comment on peut réaliser l'invention.
<I>Exemple:</I> On introduit 304 parties de 1-chloro-8- benzoylaminoanthraquinone, 95,2 parties de 2,6-diaminoanthraquinone, 170 parties de carbonate de soude anhydre, 20,4 parties de cuivre en poudre et 50,8 parties d'iode (rap port moléculaire J : Cu =<B>1,25:</B> 1) dans 3600 parties de nitrobenzène. On chauffe la suspen sion en l'agitant à la température d'ébullition et on la maintient sous reflux à cette tempé rature pendant 24 heures.
Après refroidissement, on isole le produit par filtration et on le lave au nitrobenzène. On sépare par entraînement à la vapeur le nitrobenzène, pour en débarrasser le produit que l'on filtre à nouveau, lave et sèche.
On obtient 284 parties de produit final, ce qui correspond à un rendement. de 80 % de la théorie. Le produit se dissout dans l'acide sulfurique concentré avec une couleur verte; après encuvage, il teint le coton en une nuance brun rouge claire.
Si l'on utilisait du chlorure cuivrique comme catalysateur dans cette réaction, on obtiendrait des résultats nettement inférieurs.
Process for the preparation of 2,6-bis (8'-benzoylamino-anthraquinonylamino-1 ') - anthraquinone. The present patent relates to a process for preparing 2,6-bis (8'-benzoylamino-anthraquinonylamino-1 ') -anthraquinone, a known compound of formula:
EMI0001.0005
This process is characterized in that a 1-halo-8-benzoylamino-anthraquinone is reacted with 2,6-diaminoanthraqüinone in the presence of a substance capable of combining with acids, in an amount sufficient to . to react with the hydrhalogenic acid set free, and in the presence of a copper-containing catalyst containing copper and iodine in a ratio of 0.9 to 2.0 atoms of iodine to one atom of copper . Preferably, the operation is carried out in the presence of a copper catalyst containing 1.1 to 1.8 atoms of iodine per atom of copper.
Copper catalysts containing copper and iodine in the ratio indicated above are very effective in the present reaction and make it possible to obtain a product which is practically free from impurities, which represents a significant industrial progress.
The yield of the process decreases sharply as one approaches the upper limit of 2 atoms of iodine per atom of copper in the catalyst. If more than 2 atoms of iodine were used, the excess would partially end up in the form of free iodine, causing an even more marked decrease in yield. In general, the range is from just under one atom to about 1 atom 1 /. of iodine per copper atom represents the optimum range, although this may vary somewhat depending on the nature of the reactants.
As the substance capable of combining with acids, any of the known substances which are ordinarily used for this purpose can be used.
The amount of catalyst is not critical. Generally speaking, an amount of about <B> 0.1 </B> atom of copper per molecide of diaminoanthraqtunone is the practical lower limit. It is quite possible that the catalyst actually enters into a reaction and is. regenerated continuously, so that its action would be more like that of a condensing agent than that of a catalyst itself.
Excessive amounts of catalyst simply waste copper and iodine and generally optimum results are obtained in the range of 0.1 to 1.0 atom of copper per molecule of diaminoanthraquinone.
The reaction can be carried out in the presence of a solvent. The nature of this solvent is not critical. The inert solvents ordinarily used in other Ullmann reactions are well suited. They must, of course, be inert under the reaction conditions, even at the high temperatures of 150-250 ° C. which are likely to be reached. The preferred solvent is nitrobenzene. It is also possible to operate without any solvent, but, for ease of mechanical handling, it is desirable to use a solvent or diluent.
The following example, in which the parts are expressed by weight, shows how the invention can be carried out.
<I> Example: </I> 304 parts of 1-chloro-8-benzoylaminoanthraquinone, 95.2 parts of 2,6-diaminoanthraquinone, 170 parts of anhydrous sodium carbonate, 20.4 parts of powdered copper and 50.8 parts of iodine (molecular ratio J: Cu = <B> 1.25: </B> 1) in 3600 parts of nitrobenzene. The slurry is heated with stirring to the boiling temperature and kept under reflux at this temperature for 24 hours.
After cooling, the product is isolated by filtration and washed with nitrobenzene. The nitrobenzene is separated by steam stripping to free the product which is filtered again, washed and dried.
284 parts of final product are obtained, which corresponds to a yield. 80% of theory. The product dissolves in concentrated sulfuric acid with a green color; after vatting, it dyes the cotton in a light reddish brown shade.
If cupric chloride were used as a catalyst in this reaction, much inferior results would be obtained.
