AUSGEaEBEN AM 17. DEZEMBER 1919OUTPUT ON DECEMBER 17, 1919
in NÜRNBERG.in NUREMBERG.
Es wurde gefunden, daß man einen neuen wertvollen Farbstoff J der Indigoreihe ^erhält, der die pflanzliche und tierische Faser in reinen wesentlich grüneren Tönen anfärbt, als Indigo selbst, wenn man auf eine Auflösung von Indigo in konzentrierter Schwefelsäure bei niedriger Temperatur Acetaldehyd oder Paraldehyd einwirken läßt.It has been found that a new valuable dye J of the indigo series ^ is obtained, which dyes the vegetable and animal fibers in pure, much greener tones than Indigo itself, if one involves dissolving indigo in concentrated sulfuric acid low temperature acetaldehyde or paraldehyde to act.
In der Patentschrift 242532 wird ein Verfahren zur^Gewinnung von Indigo und sonstigen Farbstoffen der Indigo- und Thioindigoreihe in fein verteilter Form beschrieben, bei dem bei der Dissoziation mineralsaurer indigosalze Aldehyde der Fettreihe zugefügt werden. Der angewendete Farbstoff wird dabei chemisch unverändert, nur in feinerer Verteilung wiedergewonnen. In the patent specification 242532 a process for ^ extraction of indigo and other Dyes of the indigo and thioindigo series described in finely divided form, in which In the dissociation of mineral acid indigo salts, aldehydes are added to the fat series. Of the applied dye is chemically unchanged, only recovered in a finer distribution.
Weiter erwähnt Heller (Zeitschrift für Textilchemie, Jahrgang 2, Seite 329) die direkte Vereinigung von Formaldehyd mit Indigo unter Zuhilfenahme von Kondensationsmitteln. Bei der Kondensation von Indigo und Formaldehyd mit Hilfe konzentrierter- Schwefelsäure werden! unlösliche Produkte von blauer bis grüner Farbe erhalten, die sich durch Hydrosulfit nicht verküpen lassen und als Farbstoffe wertlos sind.Heller also mentions (Zeitschrift für Textilchemie, Volume 2, page 329) the direct combination of formaldehyde with indigo with the help of condensation agents. at the condensation of indigo and formaldehyde with the help of concentrated sulfuric acid will! insoluble products of blue to green color obtained by hydrosulphite do not vat and are worthless as dyes.
26,2 Teile Indigo werden bei o° in 800 Teilen Schwefelsäure von 66° Be gelöst und unter gutem Rühren langsam 9 Teile Paraldehyd einfließen gelassen, wobei durch gute Kühlung Sorge getragen wird, daß die Temperatur stets unter o° bleibt. Die Lösung wird auf Wasser gegossen, der ausgeschiedene Farbstoff abgesaugt, neutral gewaschen und getrocknet. Der neue Farbstoff stellt ein blaues, kupferglänzendes Pulver dar, das sich in kochendem Eisessig, Nitrobenzol sowie Anilin mit blauer Farbe löst. Aus der Hydrosulfitküpe wird Baumwolle und Wolle in grünblauen Tönen angefärbt.26.2 parts of indigo are at 0 ° in 800 parts Dissolved sulfuric acid of 66 ° Be and slowly 9 parts of paraldehyde with thorough stirring allowed to flow in, care being taken that the temperature is always maintained by good cooling remains below o °. The solution is poured onto water, the precipitated dye is suctioned off, washed neutral and dried. The new dye represents a blue, shiny copper color Powder that is in boiling glacial acetic acid, nitrobenzene and aniline with a blue color solves. Cotton and wool are dyed in green-blue tones from the hydrosulfite vat.
