Description
Verfahren zur Herstellung eines neuen Küpenfarbstoffes. Es wurde gefunden, dass man einen neuen Küpenfarbsto-ff erhält-, -wenn inan Tlhionyl- chlorid auf 2,5-Di-p-anisiilidobenzochinon einwirken lässt. Die Reaktion wird zweck mässig in Gegenwart von Verdünnungsmit teln, wie I-,Titrobenzol, gegebenenfalls in Ge genwart von säurebindenden Mitteln, durch geführt.
Der neue Farbstoff bildet ein braun schwarzes Pulver, das sich in konzentrierter Schwefelsäure mit grünlichblauer Farbe löst und Wolle aus der Hydrosulfitlküpe in echten braunvioletten Nuancen färbt.
Beispiel: 8,7 Teile 9,5-Di-p-an.isi,didobeiizochinon werden in<B>1.30</B> Teilen Nitrobenzol kalt mit 9 Teilen Tliionylchlorid versetzt, nach und nach bis zur Siedetemperatur des Gemisches erhitzt und drei Stunden bei dieser Tempe ratur gerührt. Nach dem Erkalten wird fil- triert,-gewaschen und getrocknet.
Process for the production of a new vat dye. It has been found that a new vat dye is obtained when thionyl chloride is allowed to act on 2,5-di-p-anisilidobenzoquinone. The reaction is expediently carried out in the presence of diluents, such as I- or titrobenzene, optionally in the presence of acid-binding agents.
The new dye forms a brown-black powder, which dissolves in concentrated sulfuric acid with a greenish-blue color and dyes wool from the hydrosulfite vat in real brown-violet shades.
Example: 8.7 parts of 9,5-di-p-an.isi, didobeiizoquinone in 1.30 parts of cold nitrobenzene are mixed with 9 parts of thiionyl chloride, and the mixture is gradually heated to the boiling point of the mixture and then for three hours stirred at this tempe temperature. After cooling, it is filtered, washed and dried.
