EMI1.1
Die bei der Destillation des Rohholzgeistes zurückbleibenden sogenannten Holzöle sowie Fraktionen derselben wurden in bezug auf ihr Lösungsvermögen für Zelluloseätaer oder -ester untersucht und gefunden,
EMI1.2
Fraktionen, die gänzlich Nichtlösungsmittel sind, durch Zusätze ganz geringer Mengen von Lösungsmitteln und auch Nichtlösungsmitteln für Zelluloseverbindungen gute Lösungsmittel für dieselben werden (s.
Patent Nr. 99. 665).
Es werden dabei aber auch solche Fraktionen, namentlich die höheren Fraktionen der Holzölc, in welchen alyphatische und zyklische Ketone, sowie höhere Kohlenwasserstoffe von Furfuran-und Pyroleharakter enthalten sind (über 100C) erhalten, welche für sich keine Losungsmittel für die genannten Zelluloseabkömmlinge sind und auch ni ht durch Zusatz von andern Stoffen, sowohl Lösungsmitteln,
EMI1.3
werden können.
Es wurde nun gefunden, dass ein geringer Zusatz von Wasser auch derartige Nichtlösungsmittel in Lösungsmittel zu verwandeln vermag. Um das Wasser diesen Kohlenwasserstoffen einverleiben zu können. wird zweckmässig ein Vcrteilungsmittel. vorzugsweise Äthylalkohol verwendet. Die Menge des zuzu- setzenden Wassers und Lösungsmittels muss hiebei. da ja die Zusammensetzung der Holzölfraktionen sowie der Ketonöle eine sehr verschiedene ist. durch einen einfachen Versuch ermittelt werden.
EMI1.4
20O, Alkohol (96%). um aus einem Nichtlösungsmittel ein Lösungsmittel zu werden.
Bei Azetonleichtölen genügt schon ein Zusatz von 100 Wasser und etwa 10% Alkohol, um diesen Körpern ein gutes Lösungsvermögen zu verleihen.
Die Einverleibung des Wassers kann auch ohne Lösungsmittel bewirkt werden, z. B. unter Verwendung einer Kolloidmühle oder indem unter ständigem. heftigem Schütteln das Wasser tropfenweise zugesetzt wird. Sobald die reichtige Menge Wasser zugesetzt ist. tritt ein Opalisieren der Flüssigkeit dn, woraus zu schliessen ist, dass es sich um eine kolloidale Lösung handelt.
PATENT-ANSPRÜCHE :

EMI1.1
The so-called wood oils remaining after the distillation of the raw wood spirit, as well as fractions thereof, were examined and found with regard to their dissolving power for cellulose ethers or esters,
EMI1.2
Fractions that are entirely non-solvents can become good solvents for cellulose compounds through the addition of very small amounts of solvents and also non-solvents for cellulose compounds (see Sect.
Patent No. 99,665).
However, there are also those fractions, namely the higher fractions of wood oils, in which alyphatic and cyclic ketones, as well as higher hydrocarbons of furfuran and pyrolysis character are contained (above 100 ° C), which are not and also not solvents for the named cellulose derivatives not by adding other substances, both solvents,
EMI1.3
can be.
It has now been found that a small amount of water is also able to convert such non-solvents into solvents. In order to be able to incorporate the water into these hydrocarbons. appropriately becomes a means of distribution. preferably ethyl alcohol is used. The amount of water and solvent to be added must be used. since the composition of the wood oil fractions and the ketone oils is very different. can be determined by a simple experiment.
EMI1.4
20O, alcohol (96%). to turn a nonsolvent into a solvent.
With acetone light oils, an addition of 100% water and about 10% alcohol is enough to give these bodies good dissolving power.
The incorporation of the water can also be effected without a solvent, e.g. B. using a colloid mill or by taking under constant. vigorous shaking the water is added dropwise. As soon as the sufficient amount of water has been added. If the liquid becomes opalescent, it can be concluded from this that it is a colloidal solution.
PATENT CLAIMS:
1. Procedure to make ketone oils and higher fractions of wood oils. which are neither on their own nor mixed with other hydrocarbons solvents for cellulose ether or esters to be converted into solvents for these bodies, characterized in that these nonsolvents are used
