Description
Verfahren zur Darstellung des 4-6-Dimethyl-ö-chlor-2-2'-thionaphten-h'- 7'-dichlor indolindigos. (xegenstand der vorliegenden Erfindung ist ein Verfahren zur Darstellung des 4-6 Dimethyl-5-chlor-2-2'-thionaphten-5'-7'dicblor- indolindigos, welches dadurch gekennzeichnet ist; dass man das 4-6-Dimethyl-5-chlor-3- oxythionaphten mit 5-7-Dichlorisatinchlorid kondensiert.
<I>Beispiel:</I> 22 Gewichtsteile 5,7-Dichlorisatin werden finit 22 Gewichtsteilen Phosphorpentachlorid in 100 Gewichtsteilen Benzol bis zur Beendigung der Salzsäureer)twicklung am Rückflusskühler erhitzt. Nach dem Erkalten wird eine Lösung von 21 Gewichtsteilen 4.6-Dimethyl-5-chlor- Fi-oxythionaphten in 400 Gewichtsteilen Benzol eingerührt. Die Farbstoffausscheidung beginnt sofort. Nach 3 Stunden wird abgesaugt und mit Benzol nachgewaschen.
Der 4. 6 - Dimethyl - 5- chlor-2. 2'-5' . 7'-di- chlor-thionaphthenindolindigo stellt ein blau violettes Pulver dar. Er färbt auf Baumwolle aus goldgelber Küpe eire Violett von durch weg guten Echtheitseigenschaften.
Process for the preparation of 4-6-dimethyl-ö-chloro-2-2'-thionaphten-h'- 7'-dichloro indolindigo. (The subject of the present invention is a process for the preparation of 4-6 dimethyl-5-chloro-2-2'-thionaphthene-5'-7'dicblorindolindigos, which is characterized; that the 4-6-dimethyl- 5-chloro-3-oxythionaphthene condensed with 5-7-dichloroisatin chloride.
<I> Example: </I> 22 parts by weight of 5,7-dichloroisatin are finitely heated to 22 parts by weight of phosphorus pentachloride in 100 parts by weight of benzene until the development of hydrochloric acid has ended in the reflux condenser. After cooling, a solution of 21 parts by weight of 4,6-dimethyl-5-chloro-fi-oxythionaphthene is stirred into 400 parts by weight of benzene. The dye excretion begins immediately. After 3 hours, it is suctioned off and washed with benzene.
The 4th 6 - dimethyl - 5-chloro-2. 2'-5 '. 7'-dichloro-thionaphthenindolindigo is a blue-violet powder. It dyes cotton from a golden-yellow vat a violet with good fastness properties.
