Description
Verfahren zur Darstellung eines Küpenfarbstoffes. Es ist gefunden worden, dass man durch Kondensation von Perylen-3.4.9.10-tetra- earbonsäure mit einer Lösung von Athyl- amin einen wertvollen güpenfarbstoff er hält.
<I>Beispiel:</I> 1000 Gewichtsteile Perylentetracarbon- säureanhydrid werden mit etwa 4000 Gewichts teilen einer wässerigen Lösung von Äthyl- amin im Autoklaven bis zum Verschwinden der Perylentetracarbonsäure auf etwa<B>180'</B> erhitzt. Der in annähernd berechneter Menge ausgeschiedene Farbstoff wird nach dem Erkalten abfiltriert, gewaschen und ge trocknet.
Er liefert eine rotviolette Hydrosulfit- küpe, aus der Baumwolle in echten roten Tö- nen angefärbt wird. Die Lösung in konzen trierter Schwefelsäure erscheint violett, in dünnen Schichten blau gefärbt.
Process for the preparation of a vat dye. It has been found that by condensing perylene-3.4.9.10-tetra-carboxylic acid with a solution of ethylamine, a valuable high-quality dye is obtained.
<I> Example: </I> 1000 parts by weight of perylenetetracarboxylic acid anhydride are heated to about <B> 180 '</B> with about 4000 parts by weight of an aqueous solution of ethylamine in the autoclave until the perylenetetracarboxylic acid disappears. The dyestuff which has separated out in an approximately calculated amount is filtered off after cooling, washed and dried.
He supplies a red-violet hydrosulphite vat from which cotton is dyed in real red tones. The solution in concentrated sulfuric acid appears violet, colored blue in thin layers.
