Abstract

Agent of high absorption capacity for binding substances which are insoluble in water, (oil impurities), contains absorbent organic and/or inorganic substances and hydrophobic silica which has been rendered hydrophobic by treatment with organosilicon cpds. such as organohalogen silanes or which has been prepared by the prohydrolysis of silicon tetrafluoride. Sawdust or cork powder are preferably used as the absorbent organic substances since they float in water and have a high capacity, particularly for oils. Suitable absorbent inorganic substances are natural or synthetic silicates or silicas. The hydrophobic silica is preferably added to the mixture in quantities of 4-20% based on the absorbent substance.

  HAUPTPATENT Mittel hoher Absorptionsfähigkeit zum Binden nicht wasserlöslicher Substanzen
Die Erfindung betrifft ein Mittel hoher Absorptionsfähigkeit, enthaltend saugfähige organische und/oder anorganische Stoffe, zum Binden nicht wasserlöslicher Substanzen, welches sich durch erhöhte Aufnahmefähigkeit von nicht wasserlöslichen Substanzen auszeichnet.



   Für viele Zwecke, z.B. zum Schwebendhalten von organischen oder anorganischen Verunreinigungen in Wasser, zur Einarbeitung hochdisperser Füllstoffe in organische Medien und zur Beseitigung von   Ölverun-    reinigungen auf Böden und Gewässern ist es erwünscht, diesen Stoffen   organophüe    bzw. hydrophobe Eigenschaften zu verleihen bzw. Ölverunreinigungen mit derartigen hydrophobierten Substanzen zu beseitigen.



   So ist es bekannt, z. B. pulverförmige gefällte Kieselsäure durch Behandlung mit geeigneten organischen Siliciumverbindungen, z.B. Alkylchlorsilanen, in Form einer  Coatung  zu hydrophobieren. Hierbei setzt sich das Chlorsilan auch mit an der Oberfläche der Kieselsäure adsorbiertem Wasser unter Bildung von Salzsäure um. Die so hydrophobierte Kieselsäure muss anschlie ssend von der gebildeten Salzsäure befreit werden. Die Hydrophobierung wurde ferner bei pulverförmiger Kieselsäure mit Siliconölen vorgenommen. Dazu muss aber die trockene pulverförmige Kieselsäure in einer organischen Flüssigkeit suspendiert werden. Ferner ist es bekannt, auch pyrogen gewonnene Kieselsäure durch Behandlung mit Silanen in ihrer Oberfläche so zu modifizieren, dass sie hydrophobe Eigenschaften aufweist.



   Zur Beseitigung von   Ölverunreinigungen    auf Böden und Gewässern wurden auch schon Mineralien vulkanischen Ursprungs verwendet, welche durch thermische Nachbehandlung expandiert und hydrophobiert worden waren.



   Sowohl die hydrophobierten Kieselsäuren als auch die zuletzt genannten vulkanischen Mineralien sind infolge ihrer relativ aufwendigen Herstellung für die Beseitigung von   Ölverunreinigungen    oder Reinigung von Abwässern durch Schwebendhalten der zu Verunreinigungen führenden Stoffe zu teuer und daher wenig geeignet.



   Die Erfindung ging daher von der Aufgabenstellung aus, ein Mittel hoher Absorptionsfähigkeit anzugeben, welches saugfähige organische und/oder anorganische Stoffe enthält und sich durch erhöhte Aufnahmefähigkeit von nicht wasserlöslichen Stoffen auszeichnet.



   Die Erfindung ist dadurch gekennzeichnet, dass es hydrophobe gefällte und/oder hydrophobe pyrogen gewonnene feinteilige Kieselsäure nebst anderen saugfähigen organischen und/oder anorganischen Stoffen zum Binden organischer, nicht wasserlöslicher Substanzen enthält. Als besonders geeignet haben sich hierbei gefällte oder pyrogen gewonnene Kieselsäuren gezeigt, welche durch eine Behandlung mit Organohalogensilanen hydrophobiert worden sind. Es ist aber auch möglich, auf diesen zusätzlichen Arbeitsgang der Hydrophobierung zu verzichten, wenn als Zusatzstoff zu den saugfähigen Materialien eine durch Hydrolyse bzw.



  Pyrolyse von Siliziumtetrafluorid gewonnene, aus der Herstellung direkt hydrophob anfallende Kieselsäure verwendet wird. Diese kann ohne Aufbereitung als Rohprodukt, wie es bei der Herstellung vorliegt, den saugfähigen Materialien zugemischt werden.



   Als saugfähige organische Substanzen werden zweckmässigerweise Holz- oder Korkmehle verwendet, da diese Stoffe infolge ihres niedrigen spezifischen Gewichtes schwimmfähig sind und sich bekanntlich durch hohe Saugfähigkeit, insbesondere für Öle, auszeichnen.



   Als saugfähige anorganische Substanzen sind natürliche oder synthetisch gewonnene Silikate oder Kieselsäuren geeignet, welche zwar für sich allein mit Wasser suspendierbar sind, aber durch die Zugabe von den erfindungsgemäss verwendeten Zusätzen an hydrophober   sio2    in schwimmfähigem Zustand gehalten werden.  



   Zur Herstellung des Absorptionsmittels genügt es, die genannten saugfähigen organischen und/oder anorganischen Stoffe mit hydrophober Kieselsäure zu vermischen, wobei die einzelnen Teilchen von der hydrophoben Kieselsäure umhüllt werden, ohne dass sie ihre Saugfähigkeit verlieren. Zweckmässigerweise wird die hydrophobe Kieselsäure zur Mischung in Mengen von   2-100/0,    vorzugsweise   4-20 %,    berechnet auf die saugfähige Substanz, zugesetzt.



   Das Mittel nach der Erfindung eignet sich z. B.



  zur Beseitigung von aus Sammelbehältern ausgetretenen schädlichen Stoffen, insbesondere Treib- oder Heizölen, ferner auch zum Schwebendhalten von anderen nicht wasserlöslichen Substanzen, wie sie in Kokereien, bei der Russherstellung und bei der   Kunststoffher-    stellung usw. als Verunreinigung der Abwässer anfallen.



   Durch Eintragung des erfindungsgemässen Mittels in die Abwässer oder direkt in die Kläranlage werden die Verunreinigungen abgefangen und können als schaumartiger Belag des Abwassers entfernt werden.



   Bei ausgetretenen Heizölen oder Treibölen kann das erfindungsgemässe Mittel mit diesem vermischt und nach dem Zusammentragen verbrannt werden, so dass eine völlige Vermischung der Öle gewährleistet und ein Einbringen in die Erde, z. B. in der Nähe von Was; sereinzugsgebieten, verhindert wird.



   Eine andere Anwendungsmöglichkeit ergibt sich bei der Verwendung von Holzmehl, Korkmehl, Kieselgur, synthetischen Kieselsäuren als Füllstoffe für organische Medien, z. B. in der Kunststoffverarbeitung, bei Baustoffen und bei der   Gummiherstellung,    indem diese Füllstoffe durch Zumischen von hydrophober Kieselsäure eine leichtere und dauerhafte Einarbeitung ermöglichen.



   PATENTANSPRUCH 1
Mittel hoher Absorptionsfähigkeit zum Binden nicht wasserlöslicher organischer Substanzen, dadurch gekennzeichnet, dass es hydrophobe gefällte und/oder hydrophobe pyrogen gewonnene feinteilige Kieselsäure nebst anderen saugfähigen organischen und/oder anorganischen Stoffen zum Binden organischer, nicht wasserlöslicher Substanzen enthält. 



  
 



  MAIN PATENT High absorbency agent to bind water-insoluble substances
The invention relates to an agent of high absorbency, containing absorbent organic and / or inorganic substances, for binding non-water-soluble substances, which is characterized by increased absorption of non-water-soluble substances.



   For many purposes, e.g. To keep organic or inorganic contaminants suspended in water, to incorporate highly dispersed fillers into organic media and to remove oil contaminants from soils and waters, it is desirable to give these substances organophuic or hydrophobic properties or to remove oil contaminants with such hydrophobicized substances .



   So it is known, e.g. B. powdered precipitated silica by treatment with suitable organic silicon compounds, e.g. Alkylchlorosilanes to be rendered hydrophobic in the form of a coating. Here, the chlorosilane also reacts with water adsorbed on the surface of the silica, forming hydrochloric acid. The silica which has been made hydrophobic in this way must then be freed from the hydrochloric acid formed. In the case of powdered silica, the hydrophobization was also carried out using silicone oils. To do this, however, the dry powdery silica must be suspended in an organic liquid. It is also known that pyrogenic silica can also be modified in its surface by treatment with silanes so that it has hydrophobic properties.



   Minerals of volcanic origin, which had been expanded and rendered hydrophobic by thermal post-treatment, have also been used to remove oil contamination from soils and bodies of water.



   Both the hydrophobized silicas and the volcanic minerals mentioned last are too expensive and therefore unsuitable for the removal of oil contamination or the purification of waste water by holding the substances leading to contamination in suspension due to their relatively complex production.



   The invention was therefore based on the task of specifying a means of high absorption capacity, which contains absorbent organic and / or inorganic substances and is characterized by an increased absorption capacity of non-water-soluble substances.



   The invention is characterized in that it contains hydrophobic precipitated and / or hydrophobic pyrogenically obtained finely divided silica together with other absorbent organic and / or inorganic substances for binding organic, water-insoluble substances. Precipitated or pyrogenically obtained silicas which have been rendered hydrophobic by treatment with organohalosilanes have proven to be particularly suitable. However, it is also possible to dispense with this additional process of hydrophobing if, as an additive to the absorbent materials, a hydrolysis or



  Silica obtained from the pyrolysis of silicon tetrafluoride and which is directly hydrophobic from the manufacture is used. This can be added to the absorbent materials without preparation as a raw product, as is the case during manufacture.



   As absorbent organic substances, wood or cork flour is expediently used, since these substances are buoyant due to their low specific weight and are known to be characterized by high absorbency, especially for oils.



   Natural or synthetically obtained silicates or silicas are suitable as absorbent inorganic substances, which can be suspended by themselves with water, but are kept in a buoyant state by adding the hydrophobic sio2 additives used according to the invention.



   To produce the absorbent, it is sufficient to mix the absorbent organic and / or inorganic substances mentioned with hydrophobic silica, the individual particles being enveloped by the hydrophobic silica without losing their absorbency. The hydrophobic silica is expediently added to the mixture in amounts of 2-100 / 0, preferably 4-20%, calculated on the absorbent substance.



   The agent according to the invention is suitable, for. B.



  to remove harmful substances that have escaped from collecting tanks, in particular fuel or heating oils, and also to keep other non-water-soluble substances suspended, such as those that occur in coking plants, in soot production and in plastics production, etc. as contamination of waste water.



   By introducing the agent according to the invention into the waste water or directly into the sewage treatment plant, the impurities are captured and can be removed as a foam-like coating from the waste water.



   In the case of leaked heating oils or fuel oils, the agent according to the invention can be mixed with this and burned after collecting, so that a complete mixing of the oils is guaranteed and an introduction into the earth, for. B. near what; catchment areas, is prevented.



   Another possible application arises when using wood flour, cork flour, kieselguhr, synthetic silicas as fillers for organic media, e.g. B. in plastics processing, building materials and rubber production, as these fillers enable easier and permanent incorporation by adding hydrophobic silica.
