teeröle mit Ätzalkalien in der Wärme erfolgen muss, wodurch einerseits ein grosser Materialverlust entsteht (etwa 40 % der Öle werden durch diese Behandlung entfernt), anderseits viele gerbstoffähnliche Substanzen, welche gerade besonders günstige Wirkungen im Desinfektionsmittel äussern, verharzt bzw. zerstört werden.
Sohin hat das vorliegende Verfahren mit der Herstellung der bekannten Buehenholzteerpräparate und der Präparate aus ,,Hozteerkreosot" nichts gemein und bietet ihr gegenüber einen wesentlichen technischen Fortschritt, da erstmals durch die im gegenständlichen Verfahren erzeugten Desinfektionmittel jene günstige Wirkung in therapeutischer Hinsicht erzielt werden kann.
Beispiel : 100 Teile schweres Buchenholzteeröl, wie dasselbe bei der Freifeuerdestillation von Buchenholzteer erhalten wird, mit einem spezifischen Gewicht von über 1, wird mit ener verdünnten

mit kaltem Wasser unterzogen. Dies erfolgt zweckmässig im Agitator. Das so behandelte Öl wird mit etwa 10 Teilen einer 10 % igen Salzsäure oder Schwefelsäure agitiert und nach Abheben der Wasehsäure mit kaltem Wasser säurefrei gewaschen.
Man erhält so je nach Qualität des Buchenholzteeröle, 80 bis 90 Teile eines neutralen und von Stiekstoffbasen und Aldehyden befreiten Rohöles, welche man mit etwa 60 Teilen zähflüssiger, neutraler Kalife : fe, hergestellt aus Pflanzenöl, bei erhöhter Temperatur (80-100 ) so lange verrührt, bis die Mischung klar geworden ist. Das EO erhaltene Desinfektionsmittel stellt ein vb kos es 01 dar, welches für sieh oder in Mischung mit Wasser als Emulsion verwendet werden ka nn.

Procedure for the preparation of disinfectants from water-

<Desc / Clms Page number 2>
tar oils with caustic alkalis must be carried out in the heat, which on the one hand results in a great loss of material (around 40% of the oils are removed by this treatment), on the other hand many substances similar to tannins, which have particularly beneficial effects in the disinfectant, are resinified or destroyed.
Thus, the present process has nothing in common with the production of the known beechwood tar preparations and the preparations made from "wood creosote" and offers a significant technical advance compared to it, since for the first time the disinfectant produced in the present process can achieve this beneficial therapeutic effect.
Example: 100 parts of heavy beechwood tar oil, as obtained in the free-fire distillation of beechwood tar, with a specific gravity of over 1, is diluted with ener

subjected to cold water. This is best done in the agitator. The oil treated in this way is agitated with about 10 parts of a 10% strength hydrochloric acid or sulfuric acid and washed acid-free with cold water after the hydrochloric acid has been lifted off.
Depending on the quality of the beechwood tar oil, 80 to 90 parts of a neutral crude oil freed from nitrogen bases and aldehydes are obtained, which are mixed with about 60 parts of viscous, neutral caliphes: fe, made from vegetable oil, at an elevated temperature (80-100) for so long stir until the mixture is clear. The disinfectant obtained from EO represents a vb kos es 01, which can be used as an emulsion for it or in a mixture with water.
