Diejenige Amidonaphtolsulfosäure, welche aus der Dioxynaphtalinsulfosäure des Patentes No. 57114 durch Erhitzen mit Ammoniak entsteht, giebt mit gewissen Diazoverbindungen werthvolle Farbstoffe.That amidonaphthol sulfonic acid, which is derived from the dioxynaphthalene sulfonic acid of the patent No. 57114 is formed by heating with ammonia, gives with certain diazo compounds valuable dyes.
Von besonderer Bedeutung ist derjenige Farbstoff, welcher durch Einwirkung der Tetrazo-•verbindung des p-Amidobenzolazo-ct-naphtylamins auf diese Amidonaphtolsulfosäure entsteht. Das ρ -Amidobenzolazo - α - naphtylamin läfst sich zweimal diazotiren und bildet dann mit 2 Molecülen eines Amins, Phenols etc. bezw. deren Sulfosäuren Trisazofarbstoffe, welche Baumwolle ohne Beize anfärben. Solche Trisazofarbstoffe sind bis jetzt nur durch das Patent No. 40740 bekannt geworden. Die daselbst beschriebenen Farbstoffe sind jedoch wenig werthvoll und sind des schwierig zu beschaffenden ρ - Diamidoazobenzols wegen zu theuer; auch haben die Farbstoffe wenig Verwandtschaft zur vegetabilischen Faser.Of particular importance is that dye which is produced by the action of the tetrazo compound of p-amidobenzolazo-ct-naphthylamine on this amidonaphthol sulfonic acid arises. The ρ-amidobenzolazo - α - naphtylamine can be diazotized twice and then forms with two molecules of an amine, phenol, etc. respectively their sulfonic acids trisazo dyes, which dye cotton without stain. Such Trisazo dyes are heretofore only available by patent no. 40740 became known. The ones there However, the dyes described are of little value and are difficult to obtain ρ - too expensive because of diamidoazobenzene; the dyes also have little relationship to vegetable fiber.
Anders verhalten sich die Farbstoffe aus p-Amidobenzolazo - α - naphtylamin. Dieselben haben eine aufserordentlich grofse Verwandtschaft zur ungeheizten Baumwolle und sind durch ihre kräftige blauviolette Nuance ausgezeichnet. Der aus der Tetrazoverbindung des p-Amidobenzolazo-a-naphtylamins und 2 Molecülen der neuen Amidonaphtolsulfosäure dargestellte Trisazofarbstoff besitzt aufserdem gegenüber den Farbstoffen des Patentes No. 40740 die sehr werthvolle Eigenschaft, dafs. er sich auf der Faser abermals diazotiren und mit Aminen, Phenolen etc. zu neuen Farbstoffen combiniren läfst, so dafs auf diese Weise neue Farbentöne entstehen. Diese neuen Färbungen sind wesentlich kräftiger und waschechter als die ursprüngliche Ausfärbung.The dyes from p-amidobenzolazo - α - naphthylamine behave differently. The same have an extraordinarily close relationship to unheated cotton and are distinguished by its strong blue-violet shade. The from the tetrazo compound des p-amidobenzolazo-a-naphthylamine and 2 molecules the new amidonaphtholsulfonic acid represented trisazo also has opposite the dyes of patent no. 40740 the very valuable property that. he himself diazotize again on the fiber and with amines, phenols, etc. to form new dyes can be combined, so that in this way new shades of color arise. These new colors are much stronger and more washable than the original color.
Beispiel zurDarstellung des Farbstoffes: 25 kg Amidobenzolazo-a-naphtylamin werden mit 60 kg Salzsäure und 14 kg salpetrigsaurem Natron diazotirt und nach mehrstündigem Stehen bei ο bis 50C zu einer mit 40 kg Soda alkalisch gehaltenen Lösung von 52 kg ß-Amidoa-naphtolmonosulfosä'ure gegeben. Der Farbstoff bildet sich sofort und fällt zum gröfsten Theil aus. Durch Zusatz von Kochsalz wird die Fällung vervollständigt.Example for the representation of the dye: 25 kg of amidobenzolazo-a-naphthylamine are diazotized with 60 kg of hydrochloric acid and 14 kg of nitrous acid and after standing for several hours at ο to 5 0 C to a solution of 52 kg of ß-amidoa-naphtolmonosulfosä kept alkaline with 40 kg of soda 'ure given. The dye is formed immediately and for the most part precipitates. The precipitation is completed by adding table salt.
Der Farbstoff bildet ein schwarzes, metallisch glänzendes Pulver, löst sich in Wasser mit braunvioletter Farbe und färbt Baumwolle im neutralen oder schwach alkalischen, Wolle in schwach saurem Bade intensiv blauviolett.The dye forms a black powder with a metallic sheen and dissolves in water brown-violet color and dyes cotton in neutral or weakly alkaline, wool in weakly acidic baths intensely blue-violet.
