Description
Verfahren zur Herstellung von Terephthaloyl-1-(2',ö'-diäthoayanilid)-4-chlorid. Gegenstand des vorliegenden Zusatzpaten- tes ist ein Verfahren zur Herstellung von Tenephthaloyl - 1- (2',5'-,diäthogyanilid) - 4 chlorid, welches dadurch gekennzeichnet ist, dass man auf ein Mol Terephthadoylohlorid in Gegenwart von organischen Lösungsmitteln,
die nicht mit den .Säurehalogenidgaruppen reagieren, ein Mol '1-Amin -o-2,5-,diäthoxy- benzol 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 Textilhilfsmitteln Ver- wendung finden:.
_ Beispiel: 1.12 Gewichtsteile Terephthaloylchlorid werden in 400 Volumteilen Aceton .gelöst, und bei 50-WC C werden 109 Gewichtsteile salz- saures 1-Amino-.2"5-@diäthoxybenzol eingetra gen, worauf bis zur beginnenden Bildung von Terephthaloyl-@di-,(2,5-diäthoxyanilid)
zum Sieden erhitzt wind. Hierauf wird sofort fil- triert und durch starkes Abkühlen das Terephthaloyl - 1--(2';
5'-diäth,oxyanilid)-4- chlorid. abgeschieden. Dias abgesaugte und mit kaltem Aceton gewaschene Produkt wird im Vakuum bei 7immertemperatur getrocknet. Durch Einengen der Mutterlauge und an- schliessendes. Abkühlen werden weitere Men gender Verbindung erhalten.
An Stelle von Aoetan als Lösungsmittel können andere Ketone, wie Methyläthylketon der Diäthylketon, sowie Kohlenwasserstoffe, wie Benzol und Xylol, allein oder in Mi schung mit den bereits erwähnten Ketanen, ferner auch Dioxan verwendet werden.
Die erhaltene, bisher nicht bekannte Ver bindung bildet gelbe Kristalle, die bei 1,09 bis<B>1.10'</B> C schmelzen.
Process for the preparation of terephthaloyl-1- (2 ', ö'-diethoayanilide) -4-chloride. The subject of the present additional patent is a process for the production of tenephthaloyl - 1- (2 ', 5' -, diethogyanilid) - 4 chloride, which is characterized in that one mole of terephthaloyl chloride in the presence of organic solvents,
which do not react with the acid halide groups, a mole of 1-amine -o-2,5-, diethoxy benzene in the form of its mineral acid salt can act.
The compound obtained in this way and not previously known is intended to be used as an intermediate for the production of dyes, pharmaceutical products and textile auxiliaries.
_ Example: 1.12 parts by weight of terephthaloyl chloride are dissolved in 400 parts by volume of acetone, and at 50-WC C 109 parts by weight of hydrochloric acid 1-amino-.2 "5- @ diethoxybenzene are entered, whereupon terephthaloyl @ di -, (2,5-diethoxyanilide)
heated to boiling wind. It is then filtered immediately and the terephthaloyl - 1 - (2 ';
5'-diet, oxyanilide) -4- chloride. deposited. The product, which has been filtered off with suction and washed with cold acetone, is dried in vacuo at room temperature. By concentrating the mother liquor and then. Cooling down further Men gender compound are obtained.
Instead of aoetane as a solvent, other ketones, such as methyl ethyl ketone or diethyl ketone, and hydrocarbons such as benzene and xylene, alone or in admixture with the aforementioned ketanes, and also dioxane can be used.
The compound obtained, previously unknown, forms yellow crystals that melt at 1.09 to 1.10 ° C.
