Description
<Desc/Clms Page number 1>
Verfahren zur Darstellung orangefarbener Disazofarbstoffe für Wolle.
In der Stamm-Patentschrift wurde ein Vorfahren zur Darstellung von walkechten Disazofarbstoffen beschrieben, welches darin besteht, dass man die Tetrazoverbindnngen der Benzidin- oder Tolidin-m-disulfosäure mit 2 Molekülen Methylketol (α-Methylindol) oder in beliebiger Reihenfolge mit 1 Molekül Methylketol (α-Methylindol) und 1 Molokü) I-Phenyl-3-methyl-5-pyrazolon kuppelt.
Es wurde nun gefunden, dass, wenn man die genannten Tetrazoverbindungcn der Benzidin- bezw. Tolidinsulfosäuren der Formeln :
EMI1.1
EMI1.2
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

Process for the preparation of orange disazo dyes for wool.
In the parent patent, an ancestor for the preparation of mill-fast disazo dyes was described, which consists in that the tetrazo compounds of benzidine or tolidine-m-disulfonic acid with 2 molecules of methyl ketol (α-methylindole) or in any order with 1 molecule of methyl ketol (α-methylindole) and 1 Molokü) I-phenyl-3-methyl-5-pyrazolone couples.
It has now been found that if the tetrazo compounds mentioned are the benzidine or. Tolidinsulfonic acids of the formulas:
EMI1.1
EMI1.2
** WARNING ** End of DESC field may overlap beginning of CLMS **.
