Definitions

• the invention relates to a tobacco product filter, in particular to a tobacco product filter comprising ionic liquids. Further, the invention relates to a method of reducing harmful substances in the tobacco smoke.
• a cigarette filter shall reduce the fraction of harmful substances, e.g. condensate, the so called tar, and gases in the smoke of the cigarette. Furthermore, the smoke is getting somewhat milder thus some smokers remove or shorten it for a more intense taste.
• the filter is wrapped with a cork coloured mouthpiece in order to hide the brown colouring of the filter.
• most of the cigarettes manufactured in an industrial way are provided with a filter. People rolling cigarettes on their own could buy the same in a tobacco store.
• the base material for manufacturing of the cigarette filter is mostly cellulose which is obtained from wood. The cellulose is converted into cellulose acetate in a complex chemical process.
• the acetate flocs are solved in acetone and are spun into long fibres from the dope.
• the diameter of the fibres is about 30 to 50 micrometers.
• a great deal of fibres is merged to an endless band.
• the fibres are punctually glued, e.g. by triacetin, in order to maintain gas permeability.
• Such a filter can hold back particles as far as about 0.2 micrometers. Thereby, approximately 40% to 70% of the particles and up to 80% of the phenols of the tobacco smoke are hold back. Additional activated charcoal filters hold back up to 85% of the gas phase components.
• a tobacco product filter comprising a carrier material which comprises an immobilized ionic liquid.
• tobacco product filter may particularly be meant all sorts of filters which are suitable to remove harmful substances, particles, gases or the like from tobacco smoke partially or in total.
• the tobacco product filter may be suitable to form cigarette, small cigars and smoking pipes.
• tobacco has to be interpreted in a broad way and shall encompass all smokable materials.
• a method of removing harmful substances from tobacco smoke comprises providing a tobacco product filter according to an exemplary aspect and conducting tobacco product smoke through the tobacco product filter.
• the harmful substances may be removed or extracted from the tobacco smoke in a physical manner.

• a filter which comprises a carrier material having an immobilized ionic liquid, for removing of harmful substances out of tobacco product smoke.
• immobilize may here particularly denote an accretion on a carrier substrate or a carrier material. Such an accretion may particularly to be distinguished from an incorporation during the forming of a crystalline structure. Such an incorporation, e.g. as the cation of a zeolite, is typically caused by ionic bonds, while an accretion is possible due to other forces, e.g. van de Waals bonds. Summarizing, the term immobilizing, in the sense of the application, may particularly not denote a firm incorporation in a crystalline structure.

In these salts additionally organic salts and furthermore molecular auxiliary substances may be solved. In the sense of this application we see the arbitrarily defined limit of 100° C. of the melting points of ionic liquids in a broader sense and include as well such liquefied salts having a melting point of above 100° C. but below 200° C. Because they do not differ in their characteristics aside from that.
• Ionic liquids exhibit some very interesting characteristics, e.g. having a very low, virtually non measurable, vapor pressure, a high liquidus range, good electrical conductivity, and interesting solvation characteristics. These characteristics predestine ionic liquids for different fields of technical applications.
