Description
Verfahren zur Herstellung von Chlorterephthaloyl-1-(4'-nitranilid)-4-chlorid. Gegenstand,des vorliegenden Zusatzpaten- tes ist ein Verfahren zur Herstellung von Chlorterephthaloyl-l-(4'-nitranilid)-4-chlorid, welches idaadurch gekennzeichnet ist, dass man auf ein Mol Chlorteiephthaloylchlorid in Ge- genwart von organischen Lösungsmitteln,
.die nicht mit den Säurehalogenidgruppen reagie ren, ein. Mol 4,Nitranilin in Form seines mineralsauren Salzes einwirken lässt.
Die so erhaltene, bisher nicht bekannte Verbindung soll als Zwischenprodukt für die Herstellung von Farbstoffen., pharmazeuti- schen Produkten und Textilhilfsmitbeln Ver wendung finden.
Beispiel: 1'30 Gewichtsteile Chlorterephthaloyl- c hloric <B>1</B> werden, in. 600 Volumteilen Aceton gelöst, und bei <B>50-601'</B> C werden.
87 Ge wichtsteile salzsaures 4-Nitranilin eingetra gen, worauf bis zur beginnenden Bildung von Chlorterephfihaloyl-di-(4-nitranilid) zum Sie den erhitzt wird. Hierauf wird sofort filtriert und durch starkes Abkühlen das Chlortereph- thaloyl-1-(4'-nitranilid)-4-ohlorid abgeschie den.
Das abgesaugte und mit kaltem Aceton gewaschene Produkt wird im Vakuum bei Zimmerbemperatur getrocknet. Durch Ein engen der Mutterlauge und anschliessendes Abkühlen werden weitere Mengen der Ver bindung erhalten.
An Stelle von Aceton als Lösungemitbel können andere Betone, wie Methyläthy lketon oder Diäthylketon, sowie Kohlen wasserstoffe, wie Benzol und Xylol, allein oder in Mi schung mit den bereits erwähnten Ketonen, ferner auch Dioxan verwendet werden..
Die erhaltene, bisher nicht bekannte Ver bindung bildet farblose Kristalle, die bei 94 bis 9'5 C schmelzen.
Process for the preparation of chloroterephthaloyl-1- (4'-nitranilide) -4-chloride. The subject of the present additional patent is a process for the production of chloroterephthaloyl-1- (4'-nitranilide) -4-chloride, which is characterized in that one mole of chloroterephthaloyl chloride in the presence of organic solvents,
.which do not react with the acid halide groups. Mol 4, nitroaniline in the form of its mineral acid salt.
The previously unknown compound obtained in this way is intended to be used as an intermediate for the production of dyes, pharmaceutical products and textile auxiliaries.
Example: 1'30 parts by weight of chloroterephthaloyl-chloric <B> 1 </B> are dissolved in 600 parts by volume of acetone and at <B> 50-601 '</B> C.
Enter 87 parts by weight of hydrochloric acid 4-nitroaniline, after which it is heated to you until chloroterephihaloyl-di- (4-nitranilide) begins to form. It is then filtered immediately and the chloroterephthaloyl-1- (4'-nitranilide) -4-chloride is deposited by vigorous cooling.
The product which has been filtered off with suction and washed with cold acetone is dried in vacuo at room temperature. By narrowing the mother liquor and then cooling it, further amounts of the compound are obtained.
Instead of acetone as a solution agent, other concretes such as methyl ethyl ketone or diethyl ketone, and hydrocarbons such as benzene and xylene, alone or in admixture with the ketones already mentioned, and also dioxane can be used.
The previously unknown compound obtained forms colorless crystals that melt at 94 to 9'5 ° C.
