Description
Zusatzpatent zum Hauptpatent Nr. 208929. Verfahren zur Herstellung von mit dianotierten aromatischen Aminen unter Bildung eines waschecht gefärbten Cellulosederivates reagierender Cellulose. Es wurde gefunden, dass man eine mit dianotierten aromatischen Aminen unter Bil dung eines waschecht gefärbten Cellulose- derivates reagierende Cellulose erhält, wenn man Cellulose mit einer Lösung von N-Oxy- methyl-salicylsäureamid in Gegenwart einer Säure behandelt und das behandelte Material darauf erhitzt.
Als Säure kann man beispielsweise Ameisensäure benützen. Als Temperatur, auf die die behandelte und zweckmässig getrock nete Cellulose zu erhitzen ist, wird vorteil haft eine solche zwischen 100-150o ge wählt.
Die so behandelte Cellulose, ein festes, farbloses Material, reagiert mit dianotierten aromatischen Aminen unter Bildung eines waschecht gefärbten Cellulosederivates.
Für das angegebene Verfahren wird der Schutz nur soweit beansprucht, als es sich nicht um eine für die Textilindustrie in Be- tracht kommende Behandlung von Textil fasern zum Zwecke deren Veredlung handelt. <I>Beispiel:</I> Cellulose wird in einer 10 o/oigen Lösung von N-Oxymethyl-salicylsäureamid, die 0,3 bis 0,5'/o Ameisensäure enthält, während 15 Minuten bei 40-50o imprägniert, ab gequetscht, bei 50-60o getrocknet, und während 4 Stunden auf 110-115o erhitzt.
Nach dem Auswaschen mit siedend heissen; Wasser und Trocknen resultiert eine Cellu- lose, auf welcher durch Einwirkenlassen von dianotierten aromatischen Aminen, wie z. B. dianotiertem Anilin oder dianotiertem 1-Amino- 2-methoxy-4-nitrobenzol, waschechte Färbun gen erzeugt werden können.
Additional patent to main patent no. 208929. Process for the production of cellulose which reacts with dianotized aromatic amines to form a washfast colored cellulose derivative. It has been found that cellulose which reacts with dianotized aromatic amines to form a washfast colored cellulose derivative is obtained if cellulose is treated with a solution of N-oxymethyl salicylic acid amide in the presence of an acid and the treated material is heated on it.
For example, formic acid can be used as the acid. The temperature to which the treated and appropriately dried cellulose is to be heated is advantageously chosen between 100-150o.
The cellulose treated in this way, a solid, colorless material, reacts with dianotized aromatic amines to form a washable, colored cellulose derivative.
For the specified process, protection is only claimed insofar as it is not a question of a treatment of textile fibers for the purpose of their finishing that is considered in the textile industry. <I> Example: </I> cellulose is impregnated in a 10% solution of N-oxymethylsalicylic acid amide containing 0.3 to 0.5% formic acid for 15 minutes at 40-50 °, squeezed off , dried at 50-60o, and heated to 110-115o for 4 hours.
After washing with boiling hot; Water and drying results in a cellulose, on which the action of dianotized aromatic amines, such as. B. dianotized aniline or dianotized 1-amino-2-methoxy-4-nitrobenzene, washable Färun gene can be generated.
