Description

Verfahren zur Darstellung von Küpenfarbstoffen. Zusatz zum Patent 386057. In dem Patent 386057 ist gezeigt worden, daß man durch Einwirkung von Ammoniak oder primären aliphatischen oder aromatischen Aminen auf Perylen-3 # q. # 9 # iö-tetracarbonsäure oder ihre Derivate echte rote bis blauviolette Küpenfarbstoffe erhält.Process for the preparation of vat dyes. Addition to the patent 386057. In the patent 386057 it has been shown that by exposure to ammonia or primary aliphatic or aromatic amines on perylene-3 # q. # 9 # iö-tetracarboxylic acid or their derivatives contain true red to blue-violet vat dyes.

Es ist nun weiter festgestellt worden, daß sich das Perylentetracarbonsäuremonoimid oder seine Derivate in analoger Weise, wie es für die Perylentetracarbonsäure im Patent 386o57 beschrieben ist, mit Ammoniak oder primären Aminen umsetzen läßt, wobei neue Küpenfarbstoffe erhalten werden.It has now been further found that the perylenetetracarboxylic acid monoimide or its derivatives in a manner analogous to that for perylenetetracarboxylic acid im Patent 386o57 is described, can be reacted with ammonia or primary amines, whereby new vat dyes are obtained.

Perylentetracarbonsäuremonoimid oder seine Derivate können gemäß dem Verfahren des Patentes 4112 17 durch Spaltung von Perylentetracarbonsäurediimid mit Schwefelsäure unter gemäßigten Bedingungen erhalten werden.Perylentetracarbonsäuremonoimid or its derivatives can be obtained with the method of the patent 4112 17 by cleavage of perylenetetracarboxylic with sulfuric acid under mild conditions according to.

B eispiel.Example.

io Gewichtsteile Perylentetracarbonsäuremonoimid werden mit etwa 6o Gewichtsteilen Anilin so lange unter Rühren zum gelinden Sieden erhitzt, bis das Monoimid verschwunden ist. Man nimmt dann die etwas abgekühlte Schmelze mit überschüssiger verdünnter Salzsäure auf, filtriert, wäscht und trocknet.10 parts by weight of perylenetetracarboxylic acid monoimide are about 6o Parts by weight of aniline heated to gentle boiling while stirring until the Monoimide has disappeared. The slightly cooled melt is then taken with excess dilute hydrochloric acid, filtered, washed and dried.

Der so erhaltene Farbstoff bildet eine violette Küpe. Auf Baumwolle erhält man daraus ein Rot von guter Chlorechtheit. In conc. Schwefelsäure löst sich der Farbstoff violett mit scharlachroter Fluoreszenz.The dye thus obtained forms a purple vat. On cotton this gives a red with good fastness to chlorine. In conc. Sulfuric acid dissolves the dye violet with scarlet fluorescence.

In ähnlicher Weise wie mit Anilin, läßt sich das Perylentetracarbonsäuremonoimid auch mit anderen Aminen kondensieren. So erhält man mit p-Chloranilin einen Farbstoff, welcher aus violetter Küpe auf Baumwolle bläulichrote Ausfärbungen erzeugt.In a similar way as with aniline, the perylenetetracarboxylic acid monoimide also condense with other amines. So with p-chloroaniline you get a dye, which creates bluish-red colorations from a violet vat on cotton.
