Description

Verfahren zur Geruchsverbesserung von bei .der Sulfatzellstoffabrikation o. dgl. gewonnenem Terpentinöl. . Bekanntlich enthalten die in der Zellulosefabrikation nach dem Sulfatverfahren o. dgl. als \ebenprodukt entstehenden sogenannten Sulfatterpentinöle übelriechende Sulfidverbindungen (Merkaptane), die die 'Verwertung dieser öle erschweren. Alle Versuche der dauernden Entfernung dieser Sulfidverbindungen sind bisher gescheitert. Vorliegende Erfindung erreicht das Ziel .durch Behandlung genannter S.ulfatterpentinöle mit Metalloxyden oder ,den entsprechenden Metallen, insbesondere auch Eisen, die in Alkalien, wie Ammoniak, Natriumhydroxyd, Kaliumhydroxyd gelöst sind, unter Erhitzen auf ioo bis i2o° mit oder ohne Druckerhöhung und gleichzeitiger Einwirkung von Wasserstoff, wobei die Schwefelverbindungen der entsprechenden Metalle entstehen.Process for improving the odor of sulphate pulp production or the like. Obtained turpentine oil. . It is well known that they are contained in cellulose production So-called sulfate pentine oils formed as a by-product after the sulfate process or the like foul-smelling sulphide compounds (mercaptans) that make it difficult to utilize these oils. All attempts to permanently remove these sulfide compounds have so far failed. The present invention achieves the object by treating said sulphate turpentine oils with metal oxides or the corresponding metals, especially iron, the dissolved in alkalis such as ammonia, sodium hydroxide, potassium hydroxide, with heating to ioo to i2o ° with or without pressure increase and simultaneous exposure to hydrogen, whereby the sulfur compounds of the corresponding metals are formed.

Beispiel. 500 kg Sulfatterpentinöl werden mit 25 kg 2o prozentiger Natronlauge, in der entweder 21/a kg Zinkoxyd oder 2 kg Bleiglätte gelöst sind, im Autoklauen auf ioo bis 12o° erhitzt. Gegebenenfalls kann das Erhitzen auch ohne Druckerhöhung erfolgen. Hierauf wird das so behandelte Terpentinöl gewaschen und fraktioniert. destilliert. An Stelle der Natronlauge können entsprechende Mengen Kalilauge oder Ammoniak, an Stelle der Metalloxyde entsprechende Mengen des entsprechenden Metalles oder Eisen genommen werden. Während der Behandlung läßt man noch Wasserstoff auf das Sulfatterpentinöl einwirken, wobei die ungesättigten Verbindungen des Öles, die wie auch zum Teil die gesättigten Verbindungen als Sulfide (\lerkaptane) vorhanden sind, durch Katalyse beschleunigt schwefelfrei werden und Wasserstoff anlagern bzw. gesättigt und geruchlos werden. Die gewünschte Wirkung tritt bei dieser Behandlung in I bis 5 Stunden ein. Der gegebenenfalls anzuwendende Druck kann beispielsweise 1/" bis 3 Atm. betragen.Example. 500 kg of sulphate turpentine oil are heated in the claws of a car to 100 to 120 ° with 25 kg of 2o percent sodium hydroxide solution, in which either 21 / a kg of zinc oxide or 2 kg of black lead are dissolved. If necessary, the heating can also take place without increasing the pressure. The turpentine oil treated in this way is then washed and fractionated. distilled. Corresponding amounts of potassium hydroxide or ammonia can be used in place of the sodium hydroxide solution, and corresponding amounts of the corresponding metal or iron in place of the metal oxides. During the treatment, hydrogen is allowed to act on the sulphate turpentine oil, whereby the unsaturated compounds of the oil, which, like some of the saturated compounds, are present as sulphides (\ lerkaptans), are accelerated by catalysis and become sulfur-free and hydrogen accumulate or become saturated and odorless . The desired effect occurs in 1 to 5 hours with this treatment. The pressure to be used, if necessary, can be, for example, 1 / "to 3 atm.
