Description
Verfahren zur Herstellung von einem neuen Küpenfarbstoff. Es wurde gefunden, dass man einen neuen Küpenfarbstoff erhält, wenn man 2.1-Naplhthindoxyl mit 7-Chlorisatin kon densiert.
Der neue Farbstoff stellt ein braunes Pulver dar, das sich in Schwefelsäure mit blauer Farbe löst. Er bildet eine braungelbe Küpe und färbt Baumwolle in braunen Tönen von sehr guter Echtheit.
Beispiel: 188 Teile 2. 1-Naphtliindoxyl und 181,5 Teile 7-Chlorisatin werden in 4000 Teilen Alkohol suspendiert und nach Beigabe von 5 Teilen konzentrierter Sodalösung zum Sie den erhitzt. Nach mehrstündigem Kochen ist die Kondensation beendigt. Der in guter Ausbeute abgeschiedene Farbstoff 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 if 2.1-Naplhthindoxyl condenses with 7-Chlorisatin.
The new dye is a brown powder that dissolves in sulfuric acid with a blue color. It forms a brownish yellow vat and dyes cotton in brown shades of very good fastness.
Example: 188 parts of 2. 1-Naphtliindoxyl and 181.5 parts of 7-chloroisatin are suspended in 4000 parts of alcohol and, after adding 5 parts of concentrated soda solution, heated to you. After several hours of boiling, the condensation has ended. The dye deposited in good yield is filtered off, washed and dried.
