Description
<B>Zusatzpatent</B> zum Hauptpatent Nr.219414. Verfahren zur Herstellung eines Küpenfarbstoffes. Es wurde gefunden, dass ein wertvoller Küpenfarbstoff hergestellt werden kann, wenn man 1 Mol Fluoranthen-4-carbons.äure oder eines ihrer funktionellen Derivate mit 1 Mol 1-Amino-5-benzoylaminoanthrachinon umsetzt.
Der Farbstoff stellt ein gelbbraunes Pul ver dar, das sich in konzentrierter Schwefel säure mit roter Farbe löst, sich bei 320 zer setzt und Baumwolle aus schwarzbrauner Küpe in rotstichiggelben Tönen färbt.
Als funktionelles Derivat der Fluor- anthen-4-:carbonsäure wird zweckmässig ihr Halogenid, insbesondere das Chlorid, das durch Behandeln der freien Carbonsäure mit z. B. Thionylchlorid erhältlich ist, ver wendet.
Die Umsetzung erfolgt vorteilhaft durch Erhitzen der Komponenten in Lösungs- oder Verdünnungsmitteln, wie z. B. Di- oder Tri- chlorbenzol, Nitrobenzol, Naphthalin oder Chlornaphthalin. <I>Beispiel:</I> 12,3 Teile Fluoranthen-4-carbonsäure, her gestellt nach Annalen der Chemie, Band 488, S. 111, werden in 400 Teilen trockenem o-Dichlorbenzol suspendiert und mit 12 Tei len Thionylchlorid 1 Stunde bei 110-120' gerührt.
Hierauf werden 40 Teile abdestil- liert, wobei mit dem Dichlorbenzol sämtliches überschüssiges Thionylchlorid übergeht. Die Lösung des so erhaltenen Fluoranthen-4-car- bonsäurechlorides lässt man auf<B>150'</B> abküh len, gibt 34,2 Teile 1-Amino-5-benzoylamino- anthrachinon; zu und rührt drei Stundenbei 150 bis<B>160'</B> weiter.
Nach dem Erkalten wird der gebildete Farbstoff abgesaugt, mit Dichlor- benzol und Alkohol gewaschen und ge trocknet.
<B> Additional patent </B> to main patent number 219414. Process for the production of a vat dye. It has been found that a valuable vat dye can be produced if 1 mole of fluoranthene-4-carboxylic acid or one of its functional derivatives is reacted with 1 mole of 1-amino-5-benzoylaminoanthraquinone.
The dye is a yellow-brown powder that dissolves in concentrated sulfuric acid with a red color, decomposes at 320 and dyes cotton from a black-brown vat in reddish-yellow tones.
As a functional derivative of the fluorophene-4-: carboxylic acid, its halide, in particular the chloride, which is obtained by treating the free carboxylic acid with z. B. thionyl chloride is available, ver used.
The reaction is advantageously carried out by heating the components in solvents or diluents, such as. B. Di- or trichlorobenzene, nitrobenzene, naphthalene or chloronaphthalene. <I> Example: </I> 12.3 parts of fluoranthene-4-carboxylic acid, produced according to Annalen der Chemie, Volume 488, p. 111, are suspended in 400 parts of dry o-dichlorobenzene and mixed with 12 parts of thionyl chloride for 1 hour stirred at 110-120 '.
40 parts are then distilled off, all excess thionyl chloride passing over with the dichlorobenzene. The solution of the fluoranthene-4-carboxylic acid chloride thus obtained is allowed to cool to 150, and 34.2 parts of 1-amino-5-benzoylamino-anthraquinone are added; and stir for three hours at 150 to 160 '.
After cooling, the dye formed is filtered off with suction, washed with dichlorobenzene and alcohol and dried.
