   Österreichische PATENTSCHRIFT Nr. 16508. FIRMA RÜTGERSWERKE-AKTIENGESELLSCHAFT IN BERLIN. 



   Verfahren zur Herstellung   geruchloser     Teer-und Mineralöle.   



   Von allen zur Zeit zur Holzimprägnierung verwendeten Stoffen haben sich bekanntlich die schweren Teeröle am besten bewährt ; der allgemeinen Verwendung derselben für die verschiedenen   Imprägnierungszwecke   steht aber bislang der penetrante Geruch dieser Öle hindernd im Wege. Es ist wohl schon mehrfach der Versuch gemacht worden, diesen Geruch zu beseitigen, doch ist die Herstellung eines für alle in Frage kommenden Zwecke genügend geruchschwachen Teer- oder Mineralöles mit einfachen technischen   Hilfsmitteln   bisher nicht gelungen. Nach vorliegendem Verfahren wird ein geruchloses   Ö !   erhalten, das gegenüber den   gewöhnlich   angewendeten Imprägnierungsölen noch weitere wesentliche Vorzüge hat.

   Es ist bedentend viskoser, hat ein höheres spezifisches Gewicht als das zu seiner Herstellung   benutzte Rohöl   und enthält weniger leicht flüchtige Bestandteile, was eine Verminderung der Feuersgefahr bei seiner Anwendung in geschlossenen Räumen, wie Bergwerken und Häusern zur Folge hat. 



   Das Verfahren besteht. darin, dass man dem geruchlos zu machenden Öl einen Aldehyd oder ein Keton, wie Formaldehyd oder Aceton, oder   Gemische   dieser Körper zusetzt,   zweckmässig   unter Säure- oder Alkalizusatz, dann erhitzt und längere Zeit Wasserdampf

   Austrian PATENT NO. 16508. FIRMA RÜTGERSWERKE-AKTIENGESELLSCHAFT IN BERLIN.



   Process for the production of odorless tar and mineral oils.



   Of all the substances currently used for impregnating wood, it is well known that the heavy tar oils have proven to be the best; the general use of the same for the various impregnation purposes has hitherto stood in the way of the penetrating odor of these oils. Attempts have already been made several times to eliminate this odor, but the production of a tar or mineral oil with a sufficiently weak odor for all purposes with simple technical aids has not yet been successful. According to the present procedure, an odorless Ö! obtained, which has other significant advantages over the commonly used impregnation oils.

   It is considerably more viscous, has a higher specific weight than the crude oil used for its production and contains less volatile constituents, which results in a reduction in the risk of fire when used in closed spaces such as mines and houses.



   The procedure persists. in that one adds an aldehyde or a ketone, such as formaldehyde or acetone, or mixtures of these bodies to the oil to be made odorless, expediently with the addition of acid or alkali, then heated and steam for a long time
