Description
Verwendung von Polyethylenamin zur Absorption von geruchsaktiven Stoffen Use of polyethylene amine to absorb odor-active substances
Die Erfindung betrifft die Verwendung von Polyethylenimin zur Absorption von geruchsaktiven Stoffen.The invention relates to the use of polyethyleneimine for the absorption of odor-active substances.
Es ist bekannt, daß eine Reihe von Verbindungen wie Ester der Acrylsäure und Ester der Fumarsäure mit langkettigen Polyterpenalkoholen eine große Zahl olfaktorisch wirksamer Komponenten komplex oder chemisch binden können und sich deshalb als Geruchsabsorptionsmittel eignen. Bekannt ist ebenfalls, daß Zinkionen und Zinkverbindungen (z.B. Zinkrizinαleat) mit Mercaptanen und Aminen stabile Bindungen eingehen. Ferner sind Bakterizide auf verschiedenen Gebieten zur Beseitigung von geruchsbildenden Mikroo rgan i sme n e in g e s e t zt wo rd en .It is known that a number of compounds, such as esters of acrylic acid and esters of fumaric acid with long-chain polyterpene alcohols, can complexly or chemically bind a large number of olfactory components and are therefore suitable as odor absorbents. It is also known that zinc ions and zinc compounds (e.g. zinc ricinaleate) form stable bonds with mercaptans and amines. Bactericides are also used in various fields to eliminate odor-producing microorganisms.
Es wurde nun gefunden, daß Polyethylenimin hervorragend geeignet ist, mit Fettsäuren, Aldehyden und Ketonen stabile Absorptionsverbindungen einzugehen und diese damit geruchsunwirksam zu machen.It has now been found that polyethyleneimine is extremely suitable for forming stable absorption compounds with fatty acids, aldehydes and ketones and thus rendering them odorless.
Gegenstand der Erfindung ist dementsprechend die Verwendung von Polyethylenimin zur Absorption von geruchsaktiven Stoffen.The invention accordingly relates to the use of polyethyleneimine for the absorption of odor-active substances.
Die wichtigsten an ein Geruchsabsorptionsmittel zu stellenden Anforderungen sind gute Wirksamkeit ibei niedriger Anwendungsmenge, Preiswürdigkeit, Geruchlosigkeit, toxikologische Unbedenklichkeit, Verträglichkeit mit zu behandelnden Materialien und biologische Abbaubarkeit. Diese Anforderungen werden von Polyethylenimin in idealer Weise erfüllt.The most important requirements to be met by an odor absorbent are good effectiveness ibei lower Amount of use, value for money, odorlessness, toxicological harmlessness, compatibility with materials to be treated and biodegradability. These requirements are ideally met by polyethyleneimine.
Polyethylenimin wird durch Polymerisation von Ethylenimin hergestellt. Grundsätzlich muß der Polymerisationsgrad des erfindungsgemäß verwendeten Polyethylen imin s so hoch sein, daß das Polyethylenimin toxikologisch unbedenklich ist. Mit steigendem Polymerisationsgrad nimmt die Wasserlöslichkeit des Polyethylenimins ab. Wenngleich der Polymerisationsgrad des erfindungsgemäß verwendeten Polyethylenimins abgesehen von dem zuvor genannten Mindestpolymerisationsgrad keinen Beschränkungen unterliegt, so werden aus Gründen der leichteren Handhabbarkeit solche polymeren Ethylenimine bevorzugt, die noch eine ausreichende Wasserlöslichkeit aufweisen. Derartige Polyethylenimine sind im Handel erhältlich und dem Fachmann hinsichtlich ihrer Eigenschaften bekannt (vgl. Ullmanns Enzyklopädie der technischen Chemie, 3. Auflage, 3. Band, Seite 144, z.B. "Polymin P", Warenzeichen der BASF).Polyethyleneimine is made by polymerizing ethyleneimine. In principle, the degree of polymerization of the polyethylene imine used according to the invention must be so high that the polyethyleneimine is toxicologically harmless. As the degree of polymerization increases, the water solubility of the polyethyleneimine decreases. Although the degree of polymerization of the polyethyleneimine used according to the invention is not subject to any restrictions apart from the aforementioned minimum degree of polymerization, those polymeric ethyleneimines which still have sufficient water solubility are preferred for reasons of easier handling. Such polyethyleneimines are commercially available and are known to the person skilled in the art with regard to their properties (cf. Ullmann's Encyclopedia of Industrial Chemistry, 3rd edition, 3rd volume, page 144, for example "Polymin P", trademark of BASF).
Die erfindungsgemäße Verwendung von Polyethylenimin kann in verschiedener Weise erfolgen. Dabei richtet sich die zu verwendende Menge selbstverständlich nach der Konzentration der zu absorbierenden geruchsaktiven Stoffe in dem zu behandelnden Medium. Aufgrund ihrer leichten Handhabbarkeit bietet sich der Einsatz von wäßrigen Polyethyleniminlösungen an. Wenngleich die Polyethyleniminkonzentration in diesen Lösungen nicht von kritischer Bedeutung ist (gute Ergebnisse werden bereits bei Polyethyleniminkonzentrationen im Bereich von 0,01 % erzielt), hat sich insbesondere unter wirtschaftlichen Gesichtspunkten eine Polyethyleniminkonzentration von 0,1 bi s 10 % und vorzugsweise 1 bis 3 % bewährt.The use of polyethyleneimine according to the invention can be carried out in various ways. Doing so the amount to be used is of course dependent on the concentration of the odor-active substances to be absorbed in the medium to be treated. Because of their ease of use, the use of aqueous polyethyleneimine solutions is appropriate. Although the polyethyleneimine concentration in these solutions is not of critical importance (good results are already achieved with polyethyleneimine concentrations in the range of 0.01%), a polyethyleneimine concentration of 0.1 to 10% and preferably 1 to 3% has been found, particularly from an economic point of view. proven.
Lösungen von Polyethylenimin in Wasser oder anderen Lösungsmitteln sowie Gemischen derselben eignen sich zum Versprühen bzw. zur Vernebelung und werden bevorzugt in dieser Weise angewandt. Eine weitere bevorzugte Ausführungsform der Erfindung besteht darin, daß mit geruchsaktiven Stoffen in Berührung kommende Materialien mit Polyethylenimin imprägniert werden. So können Substanzen, Stoffe, Filter bzw. Filtermassen und Gegenstände wie Schüheinlegesohlen mit Polyethylenimin imprägniert werden,Solutions of polyethyleneimine in water or other solvents and mixtures thereof are suitable for spraying or atomizing and are preferably used in this way. Another preferred embodiment of the invention consists in impregnating materials which come into contact with odor-active substances with polyethyleneimine. So substances, substances, filters or filter masses and objects such as shoe insoles can be impregnated with polyethyleneimine,
Durchgeführte Versuche haben gezeigt, daß Polyethylenimin insbesondere Fettsäuren, Aldehyde und Ketone selbst dann praktisch vollständig bindet, wenn nur kurze Kontaktzeiten zur Verfügung stehen. Demgegenüber ist die Absorp tion von Aminen und Sulfiden weniger stark ausgeprägt, so daß ein länger andauernder Kontakt für voll befriedigende Ergebnisse erforderlich ist. Es ist deshalb häufig von Vorteil, das erfindungsgemäß verwendete Polyethylenimin zusammen mit anderen Geruchsabsorptionsmitteln zu verwenden, um sicherzustellen, daß auch Verbindungen wie Amine und Sulfide bei kurzen Kontaktzeiten vollständig absorbiert werden. Selbstverständlich kann das Polyethylenimin allein oder zusammen mit anderen Geruchsabsorptionsmitteln je nach Anwendungszweck auch zusammen mit weiteren üblichen Substanzen verwendet werden.Experiments carried out have shown that polyethyleneimine, in particular fatty acids, aldehydes and ketones, binds practically completely even when only short contact times are available. In contrast, the Absorp tion of amines and sulfides less pronounced, so that a longer contact is required for fully satisfactory results. It is therefore often advantageous to use the polyethyleneimine used according to the invention together with other odor absorbents in order to ensure that compounds such as amines and sulfides are also completely absorbed with short contact times. Of course, the polyethyleneimine can be used alone or together with other odor absorbents, depending on the application, together with other customary substances.
Die Verwendung von Polyethylenimin zur Absorption von geruchsaktiven Stoffen ist praktisch überall dort möglich, wo eine Geruchsbeseitigung erwünscht ist. Bevorzugte Anwendungsgebiete sind die Kosmetik bzw. Körperpflege, die technische Geruchsbeseitigung und die Raumluftverbesserung. So kann Polyethylenimin zum Eeispiel in Körperdeodorantien verwendet werden. Ferner können Schuheinlegesohlen mit Polyethylenimin imprägniert werden. Von besonderer Bedeutung ist die Verwendung von Polyethylenimin zur Geruchsbekämpfung bei Kläranlagen, insbesondere der bei diesen anfallenαen Abluft. Die Erfindung gibt insbesondere den Kommunen die Möglichkeit, die Anlieger von kommunalen Kläranlagen in einfacher und billiger Weise von oft sehr unangenehmen Geruchsbelästigungen zu befreien. Weitere Anwendungsbereiche, die sich zur Geruchsbeseitigung mittels Polyethylenimin eignen, sind unter anderem Ställe, Tierverwertungsanstalten, Krankenhäuser und chemische Betriebe.The use of polyethyleneimine to absorb odor-active substances is practically possible wherever odor elimination is desired. Preferred areas of application are cosmetics and body care, technical odor elimination and room air improvement. For example, polyethyleneimine can be used in body deodorants. Furthermore, shoe insoles can be impregnated with polyethyleneimine. Of particular importance is the use of polyethyleneimine for odor control in sewage treatment plants, in particular the waste air that accumulates in these. The invention in particular gives the municipalities the possibility of freeing the residents of municipal sewage treatment plants from often very unpleasant odors in a simple and inexpensive manner. Other areas of application that are suitable for odor elimination using polyethyleneimine include stables, animal processing plants, hospitals and chemical companies.
Ein weiterer Schwerpunkt der erfindungsgemäß-en Verwendung von Polyethylenimin als Geruchsabsorptionsmittel liegt auf dem Gebiet der Raumluftverbesserung. So können in die luftführenden. Leitungen, Kanäle und Schächte von Klimaund Luftumwälzungsanlagen Polyethyleniminlösungen eingesprüht werden, was zu einer kontinuierlichen Beseitigung störender und unerwünschter Geruchsstoffe führt. Andererseits können in die genannten Anlagen sowie in Abluftreinigungsanlagen Filter eingesetzt werden, die mit Polyethylenimin imprägniert sind. Auf diese Weise verringert sich die erforderliche Frischluftzufuhr, was wiederum zu einer Energieersparnis führt. Im Bereich der privaten Haushalte bietet sich insbesondere die Verwendung von Polyethyleniminlösungen in Form von Sprays zur Geruchsverbesserung in zum Beispiel Toiletten und Küchen an.Another focus of the use according to the invention of polyethyleneimine as an odor absorbent is in the field of indoor air improvement. So can in the air duct. Lines, ducts and shafts of air conditioning and air circulation systems are sprayed with polyethyleneimine solutions, which leads to a continuous elimination of unwanted and undesirable odors. On the other hand, filters which are impregnated with polyethyleneimine can be used in the systems mentioned and in exhaust air purification systems. In this way, the required fresh air supply is reduced, which in turn leads to energy savings. In the area of private households, the use of polyethyleneimine solutions in the form of sprays to improve the odor in, for example, toilets and kitchens is particularly suitable.
Beispiel 1example 1
Es wurde die Absorption einer Reihe geruchsaktiver Stoffe mit Hilfe von Polyethylenimin untersucht. Dazu wurden etwa 50 g Verbandsmull mit 100 ml einer 1,5 %igen wäßrigen Polyethyleniminlösdng getränkt und anschließend 24 Stunden luftgetrocknet. Der so imprägnierte Verbandsmull wurde in ein geschlossenes System mit einem Volumen von etwa 300 ml eingebracht. Die Zirkulation der in dem geschlossenen System vorhandenen Luft erfolgte durch eine integrierte Membranpumpe. Es wurden jeweils 0,01 g eines geruchsaktiven Stoffes in den Kreislauf eingegeben.The absorption of a number of odor-active substances was investigated with the help of polyethyleneimine. For this purpose, about 50 g of gauze were impregnated with 100 ml of a 1.5% aqueous polyethyleneimine solution and then for 24 hours air dried. The gauze impregnated in this way was introduced into a closed system with a volume of approximately 300 ml. The air in the closed system was circulated by an integrated diaphragm pump. In each case 0.01 g of an odor-active substance was introduced into the circuit.
Der Gasstrom wurde jeweils vor und nach dem Passieren des mit Polyethylenimin imprägnierten Verbandsmulls gaschromatographisch und organoleptisch geprüft. Die erhaltenen Ergebnisse sind in der folgenden Tabelle zusammenαefaßt.The gas flow was checked by gas chromatography and organoleptic before and after passing through the gauze impregnated with polyethyleneimine.

Die obigen Versuchsergebnisse zeigen, daß Fettsäuren, Aldehyde und Ketone vom Polyethylenimin praktisch vollständig gebunden werden, während Amine und Sulfide nur teilweise angelagert werden. Durch längere Verweilzeiten der Gase in der Absorberphase können jedoch auch diese Substanzen weitgehend entfernt werden, so daß organoleptische Befunde zwischen 0 und 2 erhalten werden.The above test results show that fatty acids, aldehydes and ketones are almost completely bound by the polyethyleneimine, while amines and sulfides are only partially added. However, these substances can also be largely removed by longer residence times of the gases in the absorber phase, so that organoleptic results between 0 and 2 are obtained.

Die Wirkung des Polyethylenimins kann durch Zugabe anderer Absorptionsmittel wie zum Beispiel Zinksulfat, Zinkrizinoleat, Soda und Zinkcarbonat unterstützt werden. Das austretende Luftgemisch (vgl. Beispiel 1) ist dann frei von allen eingesetzten geruchsaktiven Stoffen. Eine typische Formulierung setzt sich wie folgt zusammen:The action of the polyethyleneimine can be supported by adding other absorbents such as zinc sulfate, zinc ricinoleate, soda and zinc carbonate. The exiting air mixture (see Example 1) is then free of all odor-active substances used. A typical wording is as follows:

Alternativ wurde Aktivkohle mit einer 1,0 bis 2,0 %igen Polyethyleniminlösung getränkt oder besprüht und in Rahmen in einen Luftstrom gegeben.For air filters, porous support materials such as cotton mats, felt mats, paper or plastic mats were treated with a 1.0 to 2.0% aqueous solution of polyethyleneimine and arranged in an air stream. Alternatively, activated carbon was soaked or sprayed with a 1.0 to 2.0% polyethyleneimine solution and placed in a frame in an air stream.
