Description
Verfahren zur Iier Stellung eines Diazosalzpräparates für Färberei und Druckerei. 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-ainirio-l-anisol mit einem 1.5-naph- talindisulfosauren Metallsalz umsetzt.
Das so erhaltene neutrale 1.5-Naphtalin- disulfonat des dianotierten 3-Nitro-4-amino- 1-anisols von zum Beispiel 48% Gehalt au Nitroaminoanisolbase bildet ein fast weisses, gut haltbares, lösliches, unmittelbar zum Aus färben grundierter Baumwolle geeignetes Di- azosalzpräparat;
das zweckmässig mit geeig neten, die Ausfärbungen, die Löslichkeit und die Haltbarkeit günstig beeinflussenden Zu sätzen und Färbereihilfsmitteln, wie zum Bei spiel Aluminiumsulfat oder Alaun, arylsul- fonsauren Metallsalzen und dergleichen noch auf einen handelsüblichen Diazogehält einge stellt wird.
<I>Beispiel:</I> Eine aus 168 Teilen 3-Nitro-4-amino-l- anisol in üblicher Weise hergestellte konzen- trierte Lösung des Diazocblorids wird mit 189 Teilen 1.5-naphtalindisalfosanrem Na trium, Molekulargewicht 332, bis zur völligen Umsetzung verrührt; dann wird abfiltriert und das Diazosalz bei mässiger Temperatur getrocknet und unter Umständen durch Ver mischen finit geeigneten Färbereihilfastoffen 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 has been found that a diazo salt preparation with good stability for dyeing and printing is obtained if the customarily prepared mineral acid diazo salt solution of 3-nitro-4-ainirio-1-anisole is reacted with a 1,5-naphthalenedisulfonic acid metal salt.
The neutral 1,5-naphthalene disulfonate of the dianotized 3-nitro-4-amino-1-anisole obtained in this way, for example with a nitroaminoanisole content of 48%, forms an almost white, well-preserved, soluble, diazo salt preparation suitable immediately for coloring primed cotton ;
which is expediently set to a commercially available slide container with suitable additives and dyeing auxiliaries that have a beneficial effect on the color, solubility and shelf life, such as aluminum sulfate or alum, arylsulfonic acid metal salts and the like.
<I> Example: </I> A concentrated solution of the diazo chloride prepared in the usual way from 168 parts of 3-nitro-4-amino-l-anisole is mixed with 189 parts of 1.5-naphthalene disalfosanrem sodium, molecular weight 332, to complete Implementation stirred; Then it is filtered off and the diazo salt is dried at a moderate temperature and, under certain circumstances, brought into a ready-to-trade form by mixing finite suitable dyeing auxiliary substances.
These additives can also be added to the still moist diazo salt.
