Description
Diaphragmenkombination für die elektroosmotische Reinigung von Glyzerin.Diaphragm combination for the electroosmotic cleaning of glycerine.
Bekanntlich erfolgt die elektroosmotische Reinigung von Glyzerin in der Weise, daß das zu reinigende Glyzerin zwischen Diaphragmen der Einwirkung des elektrischen Gleichstromes unterworfen wird, wobei die Diaphragmen so gewählt sind, daß die beide Diaphragmen von elektronegativem oder elektropositivem Potential sind. Bei der praktischen Durchführung dieser Verfahren tritt jedoch eine Reihe von Schwierigkeiten auf. Einerseits entsteht durch kathodische bzw. anodische Wasserwanderung eine unerwünschte Verdünnung der Glyzerinfiüssigkeit. Außerdem entstehen durch Abwanderung Verluste an Glyzerin. Das schwach gelb gefärbte, elektroosmotisch gereinigte Glyzerin enthält in der Regel noch reduzierende Substanzen. Es ist ferner undurchführbar, aus der großen Zahl von Kombinationsmöglichkeiten die für den Einzelfall in Betracht kommende Diaphragmenkombination empirisch auszuwählen. As is known, the electroosmotic cleaning of glycerine takes place in such a way that the glycerine to be cleaned between diaphragms of the action the electrical direct current is subjected, the diaphragms so chosen are that the two diaphragms of electronegative or electropositive potential are. In the practice of these procedures, however, a number of issues arise of difficulties. On the one hand arises from cathodic or anodic water migration an undesirable dilution of the glycerin liquid. They also arise from emigration Loss of glycerine. The pale yellow colored, electroosmotic purified glycerine usually contains reducing substances. It is also impracticable from the large number of possible combinations that can be considered for the individual case to select the coming diaphragm combination empirically.
Es wurde nun für die elektroosmotische Glyzerinreinigung folgende Diaphragmenkombination gefunden, die die aufgeführten Nebenwirkungen nicht mehr aufweist, darin bestehend, daß als anodisches Diaphragma Linoxyn, als kathodisches Diaphragma dicht gewebtes Segeltuch benutzt wird. It has now been made the following for electroosmotic glycerol purification Diaphragm combination found that no longer had the listed side effects has, consisting in that Linoxyn as the anodic diaphragm, as the cathodic Diaphragm of tightly woven canvas is used.
Ein Linoxyndiaphragma wird folgendermaßen hergestellt: Dünnes Seiden- oder Wollgewebe wird mit Leinöl oder Leinölfirnis imgrägniert und in einem mäßig warmen Luftstrom der Einwirkung des Luftsauerstoffes ausgesetzt. Es empfiehlt sich, das Öl durch ein Lösungsmittel (z. B. Tetrachlorkohlenstoff) zu verdünnen und durch wiederholtes Tränken und Trocknen die Porengröße des Diaphragmas herbeizuführen, bei der keine Glyzerinverluste mehr auftreten. A Linoxyndi junction is made as follows: Thin silk or woolen fabric is impregnated with linseed oil or linseed oil varnish and in a moderate way exposed to the action of atmospheric oxygen. It is advisable, to dilute the oil with a solvent (e.g. carbon tetrachloride) and through repeated soaking and drying to bring about the pore size of the diaphragm, in which there is no longer any loss of glycerine.
