Description
Verfahren zur Herstellung von Cellulosederivaten
Das so erhaltene weiße Garn hat vorzügliche Affinität zu sauren oller
direkt iiehenden Baumwol lfarbstoffcn. Beispiel
Beispiel q. Cliloracetylcellulose, z. B. in Form von cliloracetvlierter Acetatseide. wird in einem Drucl;gefiiß während a4 bis 36 Stunden den Dämpfen von Trimethylamin bei gewöhnlicher Temperatur ausgesetzt. Nach dem sorgfältigen Auswaschen zeigt das Material dieselben färberischen Eigenschaften wie das unter Beispiel a beschriebene Garn.Example q. Chloroacetyl cellulose, e.g. B. in the form of cliloracetvlierter Acetate silk. is in a pressure vessel for a4 to 36 hours to the vapors of Exposure to trimethylamine at ordinary temperature. After carefully washing out the material shows the same coloring properties as in example a described yarn.
Die so hergestellte Acetatseide oder die nach den Beispielen i, a und 3 erhältlichen Garne können, wie für Wolle üblich, mit sauren Wollfarbstoffen unter Zusatz von 17ssig- bzw. Schwefelsäure gefärbt werden. je nach der Wahl des Farbstoffes erhält man die verschiedensten Farbtöne, die sich durch ihr Feuer, ihre Ausgiebigkeit und ihre Echtheiten auszeichnen können.The acetate silk produced in this way or according to Examples i, a and 3 available yarns can, as usual for wool, with acidic wool dyes be colored with the addition of 17 sig- or sulfuric acid. depending on the choice of Dyestuff you get the most diverse color tones, which are due to their fire, their Abundance and their fastness can distinguish.
Man kann diese Materialien auch mit substantiven Baumwollfarbstoffen färben, zweckmäßig in Gegenwart von Natriumsulfat und etwas Ameisen- oder Essigsäure. Diazotierungsfarbstoffe können auf der Faser diazotiert und entwickelt werden. Beispiel Filme, die aus einem Gemisch von Chloracetvl- und Acetylcellulose hergestellt worden sind, werden während 8 Stunden mit einer io°!"inen Pyridintoluollösung auf 6o° erwärmt und dann sorgfältig ausgeNvaschen.These materials can also be used with substantive cotton dyes dye, expediently in the presence of sodium sulfate and a little formic or acetic acid. Diazotizing dyes can be diazotized and developed on the fiber. example Films made from a mixture of chloroacetyl and acetyl cellulose are heated to 60 ° for 8 hours with a 10 °! "inen pyridine toluene solution and then carefully washed out.
In diesen Beispielen kann das Pcridin oder das Trimeth_vlamin durch andere tertiäre Basen, wie Triäthylamin, Tripropylamin, Tributylaniin, Triamylamin, Diäthylbenzylamin, Chinolin, Tetraäthylhvdrazin, Tetramethyläthvlendiamin, N-alkvlierte Piperidine, 1T-alkvlierte Piperazine, ferner auch kompliziertere Verbindungen, wie Alkaloide, z. B. Nikotin, Brucin usw., ersetzt werden.In these examples the pcridine or the trimeth_vlamin can through other tertiary bases such as triethylamine, tripropylamine, tributylaniine, triamylamine, Diethylbenzylamine, quinoline, tetraethylhvdrazine, tetramethylethylenediamine, N-alkylated Piperidines, 1T-alkylated piperazines, and also more complex compounds, such as Alkaloids, e.g. B. nicotine, brucine, etc., can be replaced.
Auch kann die chloracety,lierte Cellulose durch andere Derivate, «-elche geeignete Halogenatome enthalten, seien diese rein aliphatisch oder auch aliphatisch-aromatisch gebunden, ersetzt werden.Chloracety-lated cellulose can also be replaced by other derivatives contain suitable halogen atoms, be they purely aliphatic or aliphatic-aromatic bound to be replaced.
Statt in Form von Garn oder Filmen kann die halogenacvlierte Cellulose in Form von Geweben oder in ungesponnenem Zustande zur Reaktion gebracht «-erden. Man kann auch von halogenacylierter roher Baumwolle, Linters oder Cellulose andern Ursprungs, wie z. B. von Sulfitcellulose, ausgehen.Instead of being in the form of yarn or films, the halogen-coated cellulose in the form of fabrics or in the unspun state to react «-erden. You can also use halogen-acylated raw cotton, linters or cellulose Origin, such as B. from sulfite cellulose, start.
