 vermag. Das Lösungsmittel wird endlich aus dem erhaltenen flüssigen Sol entfernt, so dass dieses die für jeden Fall erforderliche Reinheit erhält, worauf dasselbe zur erforderlichen Konzentration verdunstet wird. 



   Wünscht man z. B. eine kolloidale Wachslösung in Wasser als Dispersionsmittel, so wird zunächst in üblicher Weise eine mehr oder weniger gesättigte alkoholische   Lösung   dieses Stoffes hergestellt, wobei die Lösung dem Siedepunkt des Alkohols möglichst nahe gehalten wird. Sodann wird allmählich Wasser zugeführt, wobei dasselbe am besten ununterbrochen in kochendem Zustand erhalten wird. Es ist wichtig, durch geeignete Regelung des Verhältnisses zwischen der Zuführung der   Alkohollösung   und der Wärmezufuhr zur   Wasserlösung   den Alkoholgehalt des Wassers immer unter einer gewissen Grenze zu halten. Hat die Wasserlösung die erwünschte   Wachskonzentration erhalten, so   wird die Alkoholzufuhr unterbrochen, das Kochen aber fort

 able. The solvent is finally removed from the liquid sol obtained so that it has the purity required for each case, whereupon the same is evaporated to the required concentration.



   If you want z. B. a colloidal wax solution in water as a dispersing agent, a more or less saturated alcoholic solution of this substance is first prepared in the usual way, the solution being kept as close as possible to the boiling point of the alcohol. Water is then gradually added, and it is best to keep it boiling continuously. It is important to keep the alcohol content of the water below a certain limit by appropriately regulating the ratio between the supply of the alcohol solution and the supply of heat to the water solution. When the water solution has obtained the desired wax concentration, the supply of alcohol is interrupted, but the boiling continues

Verfahren zur Herstellung von kolloidalen Lösungen, wobei die in die kolloidale Form überzuführenden Körper ihren Molekularzustand unverändert beibehalten, dadurch gekennzeichnet, du eine krystailoide Lösung des in den kolloidalen Zustand zu überführenden Körpers erwärmt und dann im erwärmten Zustande in ein ebenfalls erwärmtes einfaches Dispersionsmittel pingeführt wird, worauf das Lösungsmittel in bekannter Weise z B. durch Kochen entfernt und die erhaltene kolloidale Lösung bis zur erforderlichen Konzentration verdunstet wird. Process for the production of colloidal solutions, whereby the bodies to be converted into the colloidal form retain their molecular state unchanged, characterized in that a crystalloid solution of the body to be converted into the colloidal state is heated and then fed in the heated state into a likewise heated simple dispersant, whereupon the solvent is removed in a known manner, for example by boiling, and the colloidal solution obtained is evaporated to the required concentration.
