von Holz verwendete, so vcrdullstete das eingefÜhrte 01 sehr schnell, wodurch dann der eigentliche Zweck der Imprägnierung, nämlich die Konservierung des Holzes, verloren ging. Wenn man die leicht flüchtigen Bestandteile des rohen Erdöles einschliesslich derjenigen Produkte, welche als Leuchtöle (Petroleum) verwendet werden, durch Destillation entfernte und den verbleibenden schwer flüchtigen Rückstand zur Imprägnierung von Holz benutzen wollte, ergab sich der Übelstand, dass infolge der Zähflüssigkeit des Stoffes eine gute Imprägnierung nicht erreicht werden

Man fährt dann mit dem Destillieren fort und verwendet den Rückstand zur Imprägnierung von Holz.
Man verfährt in folgender Weise :

Der nach dem vorliegenden Verfahren erhaltene Imprägnierstoff hat ein ausserordentlich geringes spezifisches Gewicht, ungefähr 0. 84. Da die Kosten der Imprägnierung von dem

of wood used, the introduced 01 dulled very quickly, whereby the actual purpose of the impregnation, namely the preservation of the wood, was lost. If you removed the volatile constituents of the crude petroleum, including those products that are used as luminous oils (petroleum), by distillation and wanted to use the remaining difficult-to-volatilize residue to impregnate wood, the problem arose that, due to the viscosity of the substance, a good impregnation cannot be achieved

subject to certain treatment. The crude oil is heated with sulfur and the low-boiling components are distilled off.
Distillation is then continued and the residue is used to impregnate wood.
You proceed in the following way:

The amount of sulfur required changes depending on the proportions of the crude oil.
If the crude oil is very viscous, a greater amount of sulfur is used than if it is less

The impregnation material obtained by the present process has an extremely low specific weight, approximately 0. 84. Since the cost of the impregnation of the
