Definitions
- the invention relates to a tobacco product filter, in particular a
- Tobacco product filter which has ionic liquids. Furthermore, the invention relates to a method for the reduction of pollutants in tobacco smoke.
- a cigarette filter is intended to reduce the amount of harmful substances such as condensate, the so-called tar and gases in the smoke of the cigarette.
- the filter makes the smoke a bit milder, which is why some smokers remove or shorten it for a more intense taste.
- the filter is wrapped in a cork-colored mouthpiece to prevent the filter's brown color from becoming visible.
- most manufactured cigarettes are provided with a filter. You can buy home-makers in the tobacco trade.
- Cigarette filters are mostly cellulose, which is obtained from wood. The cellulose is converted into cellulose acetate in a complex chemical process. Subsequently, the acetate flakes are dissolved in acetone and spun out of a spinning solution to long threads. The diameter of the fibers is 30 to 50 microns. Very many threads are merged into an endless band. To form the filter, the fibers are selectively glued, for example by means of triacetin, to obtain the gas permeability. Such a filter can retain particles up to a diameter of about 0.2 microns. About 40% to 70% of the particles and up to 80% of the phenols of the tobacco smoke are retained. Additional activated carbon filters retain up to 85% of the gas phase components. Brief description of the invention
- a tobacco article filter comprising a substrate having an immobilized ionic liquid.
- tobacco product filter may in particular be understood to mean all types of filters which are suitable for removing all or part of harmful substances, particles, gases or the like from tobacco smoke.
- the tobacco product filter may be suitable for forming cigarette, cigarillos and pipe filters.
- tobacco is to be interpreted broadly and includes all smokable substances.
- a method of removing pollutants from tobacco smoke comprising providing a tobacco product filter according to an exemplary aspect of the invention and passing tobacco product smoke through the tobacco product filter.
- the pollutants may be physically removed from the tobacco smoke by means of the ionic liquid or be extracted.
- Such physical extraction may in particular be distinguished from a chemical extraction in which the pollutants are chemically bound to, for example, the cation of an ionic liquid or a crystal structure, for example a zeolite.
- a filter comprising a carrier material with an immobilized ionic liquid to remove contaminants from tobacco product smoke is provided.
- immobilizing may in this case be understood in particular to be an attachment to a carrier structure or a carrier material. Such an addition may in particular be distinguished from incorporation in the construction of a crystal structure. Such solid incorporation, e.g. as a cation of a zeolite is usually carried out by means of ionic bonds, while an addition by other forces, e.g. van der Waals ties, is possible. Overall, therefore, immobilization in the sense of the application may not be understood to be a solid incorporation into a crystal structure.
- Ionic liquids are - in the sense of recognized literature (eg Wasserscheid, Peter, Welton, Tom (Eds.), "Ionic Liquids in Synthesis", published by Wiley-VCH 2003, ISBN 3-527-30515-7, Rogers, Robin D. ; Seddon, Kenneth R.

In these salts may be additionally dissolved inorganic salts and further molecular Excipients.
- Ionic liquids have very interesting properties, such as a very low to almost non-measurable vapor pressure, a very large liquidus range, good electrical conductivity and unusual solvation properties. These properties predestine them for use in various areas of technical applications. For example, they can be used as solvents (in organic and inorganic synthesis in general, in transition metal catalysis, biocatalysis, phase transfer catalysis, in multiphase reactions, in the
- ionic liquids have excellent properties as solvents or extraction agents for polymers, biopolymers (eg cellulose, chitin), biomass (eg wood, ie cellulose + lignin, ie a polyphenol, proteins), metals in eg aqueous solution, gases such as CO 2 , NO x , polar organic compounds such as alcohols, carboxylic acids, ethers, esters, ketones and amines, aromatic hydrocarbons, etc. show.
