Description

Verfahren zur Herstellung von Zubereitungen durch Mischen von wässerigen Lösungen von Celluloseäthercarbonsäuren mit Aluminiumsalzlösungen Aus Lösungen von CelI:uloseäth ercarbonsäuren oder denen Salzen, wie sie beispielsweise nach Patent 33z 203 oder Patent 712 666 hergestellt werden können, werden die Celluloseät'hercarb:onsäuren durch Zusatz von Aluminiumsalzen mehr oder weniger als Aluminiumsalze ausgefällt. Diese Ausfällung macht die technische Anwendung der viscosen Lösungen in Gegenwart von Aluminiumsalzen unmöglich,.The method for producing preparations by mixing aqueous solutions of cellulose ether carboxylic acids having from aluminum salt solutions from solutions of Celi: ercarbonsäuren uloseäth or to which salts, such as may be prepared for example according to 33z 203 or Patent 712,666, the Celluloseät'hercarb are: onic acids by the addition of Aluminum salts more or less precipitated than aluminum salts. This precipitation makes the technical application of the viscous solutions in the presence of aluminum salts impossible.

Es wurde nun gefunden, daß die oben beschriebene Ausfällung von Aluminiumsalzen der Cellulos:eätlzercarbonsäuren bei Anwesenheit von wasserlöslichen aliphatischen Oxycarbonsäuren, z. B. Glykol-, Milch-, Wein-, Citronen- und Apfelsäure, ferner von Äth@ercarbonsäuren, z. B. Methoxyessigsäure und Diglykolsäure, von Thioäthercarbonsäuren, z. B. Thiodiglykolsäure, sowie von Ameisensäure nicht eintritt. Der Zusatz der Säuren erfolgt am besten entweder zur Lösung des Ahiminiumsalzes .oder zur wässerigen Lösung der Celluloseäthercarb:onsäuren vor dem Mischen der Lösungen. Man setzt die Säuren in Mengen von mindestens 2o% der angewandten Celluloseäthercarbonsäuren hinzu. Das vorliegende Verfahren kann beispielsweise im Zeugdruck oder bei Appreturverfahren angewendet werden.It has now been found that the above-described precipitation of aluminum salts Cellulose: ether carboxylic acids in the presence of water-soluble aliphatic ones Oxycarboxylic acids, e.g. B. glycolic, lactic, tartaric, citric and malic acid, also of Äth @ ercarbonsäuren, z. B. methoxyacetic acid and diglycolic acid, of thioether carboxylic acids, z. B. thiodiglycolic acid, as well as formic acid does not occur. The addition of acids is best done either to the solution of the ammonium salt. or to the aqueous solution the cellulose ether carb: onic acids before mixing the solutions. You set the acids in amounts of at least 2o% of the cellulose ether carboxylic acids used. That The present process can be, for example, in fabric printing or in finishing processes be applied.
