Abstract

The cigarette filter contains Al metahydroxide in a rhombic crystalline form and pref. in an amt. 5-50 (20-35)% in order to improve the effectiveness of the filter in removing harmful constituents such as nicotine and other condensable and/or absorbable cpds. The amphotime nature of the additive also allows acid constituents such as malic or citric acid to be removed. Typically nicotine retention levels are increased from 33% to 51%.

Description

" Zigarettenfilter Seit: vielen Jahren erden Zigarettenfilter aus Celluloseacetat, vorzugsweise in Form von Faskabeln, verwendet, um aus dem Zigarettenrauch Nicotin und andere Verbindungen durch Kondensieren, Niederschlagen der Kondensatteilchen und/oder Absorbieren zu entfernen. Da die genannten Filter jedoch nur bis zu einem gewissen Grade die erwähnten Stoffe zu absorbieren vermögen, hat man zur Erhöhung der Absorbierwirkung die Mitverwendung von Zusätzen in oder auf dem Celluloseacetatfilter empfohlen. Als derartige Zusätze sind beispielsweise Aktivkohle, Siliciumdioxid, Aluminiumhydroxid und Aluminiumoxid bekanntgeworden. Insbesondere bei Aluminiumhydroxid als Zusatzstoff zu Zigarettenfiltern strebte man bisher eine möglichst amorphe Form mit großer Oberfläche an."Cigarette filters For many years, cigarette filters have been grounding out Cellulose acetate, preferably in the form of thread cords, is used to get out of cigarette smoke Nicotine and other compounds through condensation, precipitation of the condensate particles and / or absorbing. Since the filters mentioned only up to one To be able to absorb the substances mentioned to a certain extent, one has to increase the absorption effect, the use of additives in or on the cellulose acetate filter recommended. Such additives are, for example, activated carbon, silicon dioxide, Aluminum hydroxide and aluminum oxide became known. Especially with aluminum hydroxide As an additive to cigarette filters, the aim has so far been as amorphous as possible with a large surface.

Dennoch vermochte die bisher verwendeten Zusatzstoffe noch nicht voll zu befriedigen. Die Suche nach geeigneten Zusatzstoffen zu Zigarettenfiltern auf Celluloseacetatbasis, um Nicotin und andere kondensierbare und/oder absorbierbare Verbindungen zu binden, ist deshalb fortgesetzt worden.Nevertheless, the additives used so far were not yet fully capable to satisfy. The search for suitable additives to cigarette filters on Cellulose acetate base to nicotine and other condensable and / or absorbable Tying links has therefore continued.

Überraschend ist nun gefunden worden, daß diese Aufgabe nicht durch eine Vergrößerung der Oberfläche und damit verbunden durch eine noch weitgehendere Amorphie beim Aluminiumhydroxid einer Lösung nähergebracht wird, sondern daß ein ganz bestimmtes Aluminiunihydroxid noch dazu in kristalliner Form das Retentionsvermögen von Zigarettenfiltern auf Celluloseacetatbasis zu steigern vermag.Surprisingly, it has now been found that this task does not go through an enlargement of the surface and, associated with it, an even more extensive one Amorphism in aluminum hydroxide is brought closer to a solution, but that a very specific aluminum hydroxide even more in crystalline form to increase the retention capacity of cigarette filters based on cellulose acetate able.

Gegenstand der Erfindung ist daher ein Zigarettenfilter, das durch einen Gehalt an Aluminium-metahydroxid in rhombisch kristalliner Form gekennzeichnet ist.The invention is therefore a cigarette filter that by a content of aluminum metahydroxide in rhombic crystalline form is.

Bei dem Aluminium-metahydroxid der Formel A1O(OH) handelt es sich um kiinstlich hergestelltes Aluminium-metahydroxid, das auch unter der Bezeichnung Böhmit bekannt ist, Das rhombisch kristalline Aluminium-metahydroxid liegt in den Filtern aus Celluloseacetat in einer Menge von 5 bis 50 %, vorzugsweise von 20 bis 35% vor.The aluminum metahydroxide of the formula A1O (OH) is man-made aluminum metahydroxide, also known as Boehmite is known, The rhombic crystalline aluminum metahydroxid lies in the Filters from cellulose acetate in an amount of from 5 to 50%, preferably from 20 to 35% before.

Das Zusatzmittel nach der Erfindung ist amphoter und vermag deshalb sowohl alkalische Verbindungen, wie Nicotin, als auch saure Verbindungen, wie Äpfelsäure und Zitronensäure, zu binden.The additive according to the invention is amphoteric and therefore capable both alkaline compounds, such as nicotine, and acidic compounds, such as malic acid and citric acid, to bind.

Die Verwertung der Erfindung kann durch gesetzliche Bestimmungen, insbesondere durch die "Verordnung über Tabak und Tabakerzeugnisse", beschränkt sein.The exploitation of the invention can through legal provisions, in particular by the "Regulation on Tobacco and Tobacco Products" be.

Das Beispiel erläutert die Erfindung.The example illustrates the invention.

Ein Celluloseacetatkabel mIt einem Gesan.ttiter von 48 000 den und einem Einzeltiter von 5 den wird in an sich bekannter Weise, z.B.A cellulose acetate tow with a total titre of 48,000 den and a single titer of 5 den is used in a manner known per se, e.g.

durch Bestäuben mit Aluminium-metahydroxid' in rhombisch kristalliner Form versehen. Dann wird das Kabel in üblicher Weise zu Filtern verarbeitet. Nach dem Anbringen der Filterstöpsel an einen Tabakstrang werden die erhaltenen Zigaretten in einer standardisierten Rauchanalysiervorrichtung abgeraucht. Zum Vergleich werden Zigaretten ohne den Aluminium-metahydroxid-Gehalt im Filter mit abgeraucht. Die Ergebnisse sind in der nachstehenden Tabelle angegeben.by dusting with aluminum metahydroxide in rhombic crystalline Shape. The cable is then processed into filters in the usual way. To After attaching the filter plug to a tobacco rod, the cigarettes obtained are smoked in a standardized smoke analyzer. Be for comparison Cigarettes smoked without the aluminum metahydroxide content in the filter. the Results are given in the table below.
