Description
Verfahren zur Darstellung eines Triarylmethanfarbstoffes. Wie im Hauptpatent Nr. <B>154178</B> beschrie ben, kann die bei Substitution des Amino- restes durch höhere Alkylreste eintretende schwerere Löslichkeit von Triphenylmethan- farbstofferi dadurch beseitigt -werden, dass man gleichzeitig in diese Arnirjogruppen noch Oxyalkylgruppen einführt.
Im Hauptpatent ist ein Verfahren zur Herstellung eines gut löslichen Triamiiiotriphenylmethanfarbstoffes beschrieben, bei welchem man 4.4'-Di-(butyl- oxyä,thyl <B>-</B> amino) <B>-</B> benzhydrol mit Butyl <B>-</B> oxy- äthyl-aminobenzol kondensiert und die gebil dete Leukoverbindung zum Farbstoff oxydiert.
Nach vorliegender Erfindung erhält man einen die tierische Faser klar gelblich grün färbenden Farbstoff vermutlich der Konsti tution:
EMI0001.0021
indem man<B>1</B> Mol. 1-Naphtaldehyd-2.4-di- sulfosäure mit 2 Mol. BLityl-oxyätbyl-amino- benzol kondensiert und die Leukobase oxydiert.
<I>Beispiel:</I> <B>31,6</B> Teile 1-Naphtaldehyd-2.4-disuilfo- säure werden mit 43 Teilen Butyl-oxyäthyl aminobenzol kondensiert und die Leukover- bindung oxydiert.
Man erhält 68,4 Teile eines salzfreien Farbstoffes, der Wolle und Seide ebenso stark färbt wie die um die Hälfte grössere Menge des entsprechenden Farbstoffes aus 1-Naphtaldebyd-2.4-disulfo- säure und Diäthylaminobenzol. Das Egaii- sierungsvermögen des neuen Farbstoffes ist gleich dem des erwähnten älteren Farbstoffes. Die Färbuno# mit dem neuen Farbstoff ist, was sehr gewünscht wird, erheblich gelber, bei Abendbeleuchtung erheblich klarer gelber als die des alten.
Process for the preparation of a triarylmethane dye. As described in main patent no. 154178, the more difficult solubility of triphenylmethane dyes that occurs when the amino radical is substituted by higher alkyl radicals can be eliminated by introducing oxyalkyl groups into these amino groups at the same time.
The main patent describes a process for the preparation of a readily soluble triamilliotriphenylmethane dye, in which 4,4'-di- (butyl-oxyä, thyl - amino) - benzhydrol is mixed with butyl > - </B> Oxy-ethyl-aminobenzene condenses and the leuco compound formed is oxidized to the dye.
According to the present invention, the animal fiber is obtained with a clear yellowish green coloring, presumably of the constitution:
EMI0001.0021
by condensing 1 mole of 1-naphthaldehyde-2,4-disulfonic acid with 2 moles of BLityl-oxyätbyl-aminobenzene and oxidizing the leuco base.
<I> Example: </I> <B> 31.6 </B> parts of 1-naphthaldehyde-2,4-disulfonic acid are condensed with 43 parts of butyloxyethyl aminobenzene and the leuco compound is oxidized.
68.4 parts of a salt-free dyestuff are obtained which dyes wool and silk just as strongly as the half greater amount of the corresponding dyestuff from 1-naphthaldebyd-2,4-disulphonic acid and diethylaminobenzene. The leveling capacity of the new dye is the same as that of the older dye mentioned. The coloration # with the new dye is, which is very much desired, considerably more yellow than that of the old one under evening lighting.
