Description
Verfahren zur Herstellung eines wasserlöslichen Kondensationsproduktes. Die vorliegende Erfindung betrifft wasser lösliche Kondensationsprodukte von Aryliden aromatischer o-Oxycarbonsäuren und ein Ver fahren zu ihrer Herstellung.
Das Verfahren besteht darin, dass man Arylide aromatischer o-Oxycarbonsäuren oder deren an der Oxy- gruppe bereits acylierten Derivate in Gegen wart tertiärer Basen mit Acylierungsmitteln umsetzt, wobei die Acylierungsmittel so ge wählt sind, dass sie ausser der acylierenden Gruppe mindestens einen, gegebenenfalls nach geeigneter Umwandlung, löslichmachenden Rest enthalten.
Als Acylierungsmittelkommen in Betracht die Halogenide oder Anhydride organischer Carbonsäuren, die wenigstens eine weitere salzbildende Gruppe, wie die Carbonsäure- gruppe, die Sulfonsäuregruppe, oder einen Rest enthalten, der nach geeigneter Umwand lung den Kondensationsprodukten Löslichkeit verleiht.
Solche Verbindungen sind die Halo- genide bezw. Anhydride von Polycarbonsäuren, Sulfocarbonsäuren, ferner die Carbonsäure- halogenide, die Dialkylaminogruppen oder o)-Chloralkylgruppen enthalten, welche Reste sich nach erfolgter Kondensation in bekann ter Weise in quaternäre Ammoniumgruppen umwandeln lassen.
Die Acylierungsmittel können als isolierte Produkte verwendet wer den, ausserdem aber auch in Form technischer Rohprodukte, wie sie z. B. bei Einwirkung von Phosphorhalogeniden auf die entsprechen den Säuren oder bei Einwirkung von Chlor- sulfonsäure oder Schwefelsäureanhydrid auf die entsprechenden Carbonsäurederivate an fallen.
Vorzugsweise wird als tertiäre Base, in der die Umsetzung der Arylamide der aro matischen o-Oxycarbonsäure mit den Acylie- rungsmittehi vorgenommen wird, Pyridin ver wendet. Jedoch können.auch andere tertiäre Basen Verwendung finden. Ausserdem können der Reaktionsmischung auch noch indifferente Lösungsmittel zugesetzt werden.
Wie bereits erwähnt, können ausser den Aryliden aromatischer o-Oxycarbonsäuren selbst auch deren Derivate, die bereits in der Oxygruppe acyliert sind, verwendet werden. Dabei ist es gleichgültig, ob die 0-Acylgruppe ihrerseits schon löslichmachende Gruppen enthält oder nicht.
Diese 0-Acylgruppen sind Reste aliphatischer oder aromatischer Carbon- säuren oder Sulfonaäuren, ferner Reste wie -0C # 0X und -0C # NHs bezw. -0C # NHX, worin X ein Kohlenwasserstoffrest bedeutet.
Die so erhältlichen Kondensationsprodukte besitzen eine gute Wasserlöslichkeit. und sind wertvolle Zwischenprodukte für die Herstellung von Farbstoffen.
Vorliegendes Patent betrifft ein Verfahren zur Herstellung eines wasserlöslichen Konden sationsproduktes. Das Verfahren ist dadurch gekennzeichnet, dass man 1-(2'-Acetoxynaph- thalin-3'-carboylamino)-2-metlioxybenzol in Gegenwart einer tertiären Base mit Benzoe- säure-3-sulfochlorid umsetzt.
Die neue Verbindung stellt ein hellbraunes Pulver dar, das sich leicht in Wasser löst. <I>Beispiel:</I> 335 Gewichtsteile 1-(2'-Acetoxynaphthalin- 3'-carboylamino)-2-methoxybenzol werden in 300 Gewichtsteilen Pyridin mit 330 Gewichts teilen Belizoesäure-3-sulfoclilorid drei Stunden bei<B>800</B> C behandelt. Anschliessend wird das Pyridin im Vakuum weitgehend herausdestil liert.
Der Rückstand wird mit 500 cm' warmem Wasser versetzt, wodurch das überschüssige Benzoesäure-3-sulfochlorid zerstört wird. Das Kondensationsprodukt bleibt hierbei ungelöst. Nach Abgiessen der wässerigen Schicht und Zugabe von 4 Litern heissem Wasser wird eine klare Lösung erhalten.
Durch Zugabe von 200 Gewichtsteilen Kochsalz lässt sich das Kondensationsprodukt vollständig aussal- zen. Dabei scheidet es sich zunächst in halb fester Form ab. Nach dem Isolieren und Trocknen wird es in fester Form erhalten. Die neue Verbindung stellt ein hellbraunes Pulver dar, das sich leicht in Wasser löst.
Process for the preparation of a water-soluble condensation product. The present invention relates to water-soluble condensation products of arylides of aromatic o-oxycarboxylic acids and a process for their preparation.
The process consists in reacting arylides of aromatic o-oxycarboxylic acids or their derivatives already acylated on the oxy group in the presence of tertiary bases with acylating agents, the acylating agents being chosen so that, in addition to the acylating group, at least one, optionally after suitable conversion, solubilizing radical included.
Suitable acylating agents are the halides or anhydrides of organic carboxylic acids which contain at least one further salt-forming group, such as the carboxylic acid group, the sulfonic acid group, or a radical which, after suitable conversion, gives the condensation products solubility.
Such compounds are the halides respectively. Anhydrides of polycarboxylic acids, sulfocarboxylic acids, and also the carboxylic acid halides containing dialkylamino groups or o) -chloroalkyl groups, which radicals can be converted into quaternary ammonium groups in a known manner after condensation has taken place.
The acylating agents can be used as isolated products who the, but also in the form of technical raw products, such as. B. in the action of phosphorus halides on the corresponding acids or in the action of chlorosulfonic acid or sulfuric anhydride on the corresponding carboxylic acid derivatives.
Pyridine is preferably used as the tertiary base in which the arylamides of the aromatic o-oxycarboxylic acid are reacted with the acylation agents. However, other tertiary bases can also be used. In addition, inert solvents can also be added to the reaction mixture.
As already mentioned, in addition to the arylides of aromatic o-oxycarboxylic acids themselves, their derivatives, which are already acylated in the oxy group, can also be used. It does not matter whether the 0-acyl group itself already contains solubilizing groups or not.
These 0-acyl groups are residues of aliphatic or aromatic carboxylic acids or sulfonic acids, and residues such as -0C # 0X and -0C # NHs respectively. -0C # NHX, where X is a hydrocarbon radical.
The condensation products obtainable in this way have good water solubility. and are valuable intermediate products for the manufacture of dyes.
The present patent relates to a process for the production of a water-soluble condensation product. The process is characterized in that 1- (2'-acetoxynaphthalene-3'-carboylamino) -2-metlioxybenzene is reacted with benzoic acid-3-sulfochloride in the presence of a tertiary base.
The new compound is a light brown powder that easily dissolves in water. <I> Example: </I> 335 parts by weight of 1- (2'-acetoxynaphthalene-3'-carboylamino) -2-methoxybenzene are added to 300 parts by weight of pyridine with 330 parts by weight of belizoic acid-3-sulfocliloride for three hours at <B> 800 < / B> C treated. The pyridine is then largely distilled out in vacuo.
500 cm 'of warm water is added to the residue, which destroys the excess benzoic acid-3-sulfochloride. The condensation product remains undissolved. After pouring off the aqueous layer and adding 4 liters of hot water, a clear solution is obtained.
The condensation product can be completely salted out by adding 200 parts by weight of sodium chloride. It initially separates out in a semi-solid form. After isolating and drying, it is obtained in a solid form. The new compound is a light brown powder that easily dissolves in water.
