patentamtaCpatent officeaC
sulfosäure.sulfonic acid.
Im Haupt-Patent ist die Darstellung eines violetten Farbstoffes durch Einwirkung des Luftsauerstoffes auf die mit Alkalikarbonaten oder alkalischen Erden versetzten wässerigen Lösungen der ßx α, c^-Amidonaphtolsulfosäure beschrieben. Diese Reaction läfst sich mit demselben Erfolge auf diejenige Amidonaphtolsulfosäure ausdehnen, welche bei der Einwirkung von Schwefelsäure von iopCt. Anhydrid auf Amidonaphtol (OH: NH2 = ax : ßj entsteht. Das Verfahren ist folgendes:The main patent describes the representation of a violet dye by the action of atmospheric oxygen on the aqueous solutions of β x α, c ^ -amidonaphthol sulfonic acid mixed with alkali carbonates or alkaline earths. This reaction can be extended, with the same effect, to the amidonaphthol sulfonic acid which, upon the action of sulfuric acid, iopCt. Anhydride on amidonaphtol (OH: NH 2 = a x : ßj is formed. The procedure is as follows:
Man trägt das Chlorhydrat des Amidonaphtols allmälig in 5 Theile Schwefelsäure von ι ο pCt. Anhydrid bei gewöhnlicher Temperatur ein; das Amidonaphtol löst sich und die Temperatur der Anfangs violett, später braun gefärbten Mischung steigt auf 40 bis 500; nach 5 bis 10 Minuten giefst man das Reactionsproduct in Wasser, saugt ab und wäscht aus.The hydrochloride of amidonaphthol is gradually added to 5 parts of sulfuric acid of 1 o pCt. Anhydride at ordinary temperature; the Amidonaphtol dissolves and the temperature of the initial violet, later brown colored mixture increases to 40 to 50 0; after 5 to 10 minutes, the reaction product is poured into water, filtered off with suction and washed out.
Das so erhaltene Product unterscheidet sich seiner Constitution nach von der im Haupt-Patent genannten Amidonaphtolmonosulfosäure (ßj U1 α2) nur durch die Stellung der Sulfogruppe, welche hier nach den Gesetzen der Substitution in den zweiten Benzolkern eintritt; seinen Eigenschaften nach gleicht es der β j A1 ö2 -Amidonaphtolsulfosäure vollkommen; es löst sich wenig in heifsem Wasser mit röthlicher Farbe, dagegen leicht mit grüner Farbe in wässeriger Sodalösung.The constitution of the product obtained in this way differs from the amidonaphthol monosulfonic acid mentioned in the main patent (βj U 1 α2) only in the position of the sulfo group which, according to the laws of substitution, occurs here in the second benzene nucleus; In terms of its properties, it is completely similar to β j A 1 ö 2 -amidonaphthol sulfonic acid; it dissolves little in hot water with a reddish color, but easily with a green color in aqueous soda solution.
Durch Säuren wird es als röthlicher Niederschlag wieder ausgefällt. Eisenchlorid färbt seine wässerige Lösung braun.Acids precipitate it again as a reddish precipitate. Ferric chloride stains its aqueous solution brown.
Die Ueberführung in den Farbstoff geschieht nach dem im Haupt-Patent beschriebenen Verfahren. Das Product scheidet sich während der Reaction als' violettes Pulver aus; es ist schwer löslich in kaltem Wasser, leicht dagegen in warmem. The conversion into the dye takes place according to that described in the main patent Procedure. The product separates out as a violet powder during the reaction; it is Slightly soluble in cold water, but slightly soluble in warm water.
In concentrirter Schwefelsäure löst sich der Farbstoff mit grünlicher Farbe. Seinen tinctoriellen Eigenschaften nach gleicht er dem im Haupt-Patent beschriebenen Farbstoff vollständig; auch hier sind besonders die auf chromirter Wolle erzielten Färbungen sehr licht und walkecht.In concentrated sulfuric acid the dye dissolves with a greenish color. His tinctorial In terms of properties, it is completely similar to the dye described in the main patent; Here, too, the dyeings obtained on chromed wool are very light and fast to kneading.
