Patentirt im Deutschen Reiche vom 12. Juli 1879 ab.Patented in the German Empire on July 12, 1879.
Der Gehalt an Kreosot und der damit verbundene penetrante Geruch bildet ein wesentliches Hindernifs für die Anwendung der Mineralöle zu gewerblichen und technischen Zwecken. Alle bisher angewendeten Mittel, als Waschen mit Spiritus, Behandlung mit Säuren u. s. w., genügen nicht, diesen lästigen Begleiter zu beseitigen. The creosote content and the pungent smell associated with it are essential Obstacle to the use of mineral oils for commercial and technical purposes. All means previously used, such as washing with alcohol, treatment with acids, etc., are not enough to get rid of this annoying companion.
Mein Verfahren besteht darin, dafs die zu behandelnden rohen oder mehr oder minder gereinigten OeIe, welche aber noch immer mit dem Gehalt an Kreosot und dem davon herrührenden Gerüche behaftet sind, in einem Mischapparat mit einer Lösung von Chlorkalk in Spiritus und Aetznatron gemischt werden.My method consists in making the raw or more or less Purified oils, which, however, still have the creosote content and that resulting from it Odors are afflicted in a mixer with a solution of chlorinated lime be mixed in alcohol and caustic soda.
Die Menge dieser Lösung wird je nach dem mehr oder minder stark vorhandenen Gerüche mit s bis 9 pCt. des zu behandelnden Oeles bemessen, und zwar so reichlich, dafs nach Entfernung des Geruchs noch ein Ueberschufs von Lauge abgezogen werden kann. Die bezeichnete Lösung geht mit den Oelen weder eine chemische noch mechanische Verbindung ein, sondern nimmt nur das Kreosot und den Geruch mit sich fort.The amount of this solution will depend on the more or less strong odors present with s up to 9 pCt. of the oil to be treated, and so abundant that after removal an excess of lye can still be removed from the odor. The designated Solution does not enter into a chemical or mechanical bond with the oils, but rather only takes the creosote and smell away with it.
