Description
Als Quellungsmittel für Zellulosederivate geeignetes Gemisch. In dem Hauptpatent Nr. 1564(19 ist ein Nils Quellungsmittel für Zellulosederivate ge eignetes Gemisch beschrieben. welches aus f,inem Quellungsmittel und einem orga nischen Zusatzstoff besteht, der eine lösende Wirkung des Quellungsmittels zurückzu drängen vermag.
Als Quellungsmittel sowohl, wie als organische Zusatzstoffe sind halo- genierte Kohlenwasserstoffe, insbesondere chlorierte Kohlenwasserstoffe verschiedener Art., genannt worden.
Es hat sich nun gezeigt, dass die Quell wirkung solcher Flüssigkeitsgemische, welche ha.logenierte, insbesondere chlorierte, Kohlen wasserstoffe enthalten, mit. der Zeit sich ver ringert, und zwar anscheinend dadurch, dass unter der Einwirkung von Feuchtigkeit und Belichtung kleine Mengen der Halogene, ins besondere des Chlors, abgespalten werden.
Es ist nun gefunden worden. dass solche Gemische stabilisiert und ihnen die vorzüg lichen Eigenschaften erhalten werden kön- neu, wenn man denselben kleine Mengen von ungesättigten organischen Substanzen zu setzt. also Stoffe, welche wie Derivate von Äthylen und andern ungesättigten Kohlen wasserstoffen eine oder mehrere Doppelverbin dungen enthalten. Anscheinend sind diese ungesättigten Kohlenwasserstoffe befähigt, die abgespalteten Spuren der Halogene, ins besondere zum Beispiel das Chlor, sei es a15 solches, oder in Form der entsprechenden Was serstoffverbindungen, anzulagern.
Als beson ders wirksame ungesättigte organische Zu satzstoffe haben sich erwiesen: Olein, Linol- säure, Leinöl, Olivenöl, Butylen und derglei chen. Im allgemeinen genügt es, nur einen geringen Betrag von wenigen Prozent oder den Bruchteil eines Prozentes in das Flüssig keitsgemisch einzutragen bezw. darin zu un terhalten.
Neben den ungesättigten ölartigen Koh- lenwasserstoffen kann man den Flüssigkeits gemischen auch noch andere, tunlichst was serfreie Fette, Fettsäuren, wie zum Beispiel Stearinsäure und Öle in geringen Mengen zu setzen.
Nachstehend werden einige geeignete Bad- mischungen angegeben: <I>Beispiel 1:</I> <B>70%</B> Methylenchlarid <B>28%</B> Petroläther vom Sdp. 50 bis 60 1 % Olein 1 % Olivenöl.
<I>Beispiel Il:</I> <B>69%</B> Methylenchlorid <B>29%</B> Tetrachlorkohlenstoff 1 % Knochenöl 1 % Butylen.
<I>Beispiel</I> III: 74 % Methylenchlorid <B>23%</B> Benzol 1 % Stearinsäure 1 % Olivenöl 1 % Leinöl.
Mixture suitable as a swelling agent for cellulose derivatives. In the main patent no. 1564 (19 a Nils swelling agent for cellulose derivatives ge suitable mixture is described, which consists of a swelling agent and an organic additive that is able to suppress the dissolving effect of the swelling agent.
Halogenated hydrocarbons, in particular chlorinated hydrocarbons of various types, have been mentioned as swelling agents as well as organic additives.
It has now been shown that the swelling effect of such liquid mixtures which contain ha.logenated, in particular chlorinated, hydrocarbons. decreases over time, apparently due to the fact that small amounts of halogens, especially chlorine, are split off under the action of moisture and light.
It has now been found. that such mixtures can be stabilized and their excellent properties can be retained if small amounts of unsaturated organic substances are added to them. that is, substances which, like derivatives of ethylene and other unsaturated hydrocarbons, contain one or more double compounds. Apparently these unsaturated hydrocarbons are able to store the split off traces of halogens, especially chlorine, for example, be it a15 such or in the form of the corresponding hydrogen compounds.
The following have proven to be particularly effective unsaturated organic additives: olein, linoleic acid, linseed oil, olive oil, butylene and the like. In general, it is sufficient to enter respectively a small amount of a few percent or a fraction of a percent in the liquid mixture. to talk in it.
In addition to the unsaturated oily hydrocarbons, the liquid mixtures can also contain other, if possible, water-free fats, fatty acids such as stearic acid and oils in small quantities.
Some suitable bath mixtures are given below: <I> Example 1: </I> <B> 70% </B> methylene laride <B> 28% </B> petroleum ether with a bp. 50 to 60 1% olein 1% Olive oil.
<I> Example II: </I> <B> 69% </B> methylene chloride <B> 29% </B> carbon tetrachloride 1% bone oil 1% butylene.
<I> Example </I> III: 74% methylene chloride <B> 23% </B> benzene 1% stearic acid 1% olive oil 1% linseed oil.
