Description
Verfahren zur Herstellung eines Diazosalzpräparates für Färberei und Drückerei. Es wurde gefunden; dass man ein gut haltbares Diazosalzpräparat für Färberei und Druckerei erhält, wenn man die wie üblich hergestellte mineralsaure Diazosalzlösung von 3-Nitro-4-amino-l-toluol mit einem 1.5- naphtalindisulfosauren Metallsalz umsetzt.
Das so erhaltene neutrale 1. 55-Naphta- lindisulfonat des diazotierten 3-Nitro-4-amino- 1-toluols von zum Beispiel 28 % Gehalt an Nitrotoluidinbase bildet ein gelbes, am Licht sich bräunendes, gut haltbares, lösliches, un mittelbar zum Ausfärben grundierter Baum wolle geeignetes Diazosalzpräparat, das zweck mässig mit geeigneten, die Ausfärbungen, die Löslichkeit und die Haltbarkeit günstig be einflussenden Zusätzen und Färbereihilfs- mitteln, wie zum Beispiel Aluminiumsulfat oder Alaun,
arylsulfonsauren Metallsalzen und dergleichen noch auf einen handelsüblichen Diazogehalt eingestellt wird.
Beispiel: Eine aus 152 Teilen 3-Nitro-4-amino- 1-toluol in üblicher Weise hergestellte kon- zentrierte Lösung des Diazochlorids wird mit 200 Teilen 1.5-naphtalindisulfosaurem Na trium, Kol.-Gew. 332, bis zur völligen Um setzung verrührt; dann wird abfiltriert und. "das Diazosalz. bei mässiger Temperatur ge trocknet und unter Umständen durch Ver mischen mit geeigneten Färbereihilfsstoffen in handelsfertige Form gebracht.
Diese Zu sätze können auch dem noch feuchten Diazo- salz zugemischt werden.
Process for the production of a diazo salt preparation for dyeing and printing. It was found; that a diazo salt preparation with good shelf life for dyeing and printing is obtained if the normally prepared mineral acid diazo salt solution of 3-nitro-4-amino-1-toluene is reacted with a 1.5-naphthalene disulfonic acid metal salt.
The neutral 1,55-naphthalene disulfonate of diazotized 3-nitro-4-amino-1-toluene obtained in this way, for example with a nitrotoluidine base content of 28%, forms a yellow, browning, easily durable, soluble, direct to coloration Primed cotton, suitable diazo salt preparation, which is expediently mixed with suitable additives and dyeing auxiliaries such as aluminum sulphate or alum, which have a beneficial effect on color, solubility and durability.
arylsulfonic acid metal salts and the like is still set to a commercial Diazo content.
Example: A concentrated solution of the diazo chloride prepared in the usual way from 152 parts of 3-nitro-4-amino-1-toluene is trium with 200 parts of 1.5-naphthalene disulfonic acid, col. Wt. 332, stirred until completely implemented; then it is filtered off and. "The diazo salt. Dried at a moderate temperature and, under certain circumstances, brought into commercial form by mixing with suitable dyeing auxiliaries.
These additives can also be added to the still moist diazo salt.
