Abstract
The invention relates to a tobacco filter, which comprises a carrier material, which comprises an immobilized ionic fluid. The term tobacco filter may refer in particular to all types of filters that are suitable for removing harmful substances, particles, gases, or the like from tobacco smoke. In particular, the tobacco filter may be suitable for forming cigarette, cigarillo, and pipe filters.
Description
Technical field
The present invention relates to a tobacco articles filter, particularly have ion liquid tobacco product filter.Also relate to a kind of method that is used for reducing the tobacco smoke harmful substance in addition.
Invention field
Cigarette filter should reduce material such as the condensation product that is detrimental to health, the gas in promptly so-called tar and the smoke from cigarette.In addition, make smog softer a little, eliminate thus or shortened the dense taste of smoker through filter.Filter is surrounded by the cigarette holder of cork look for traditional cigarette with filter tip, makes that cannot to see that filter becomes brown.The cigarette that present most of industry is made has filter.The people of own cigarette can buy filter in cigar store.The stock great majority of making cigarette filter are the celluloses from timber.Cellulose is transformed into cellulose acetate through complicated chemical process.Acetate-flocculate is dissolved in the acetone subsequently, and from spinning solution
, spins long line.The diameter of said fiber is 30 to 50 microns.A lot of lines are put together formation long fibre bundle.For example use the triacetin pointwise bonding fiber in order to form filter, thereby obtain gas permeability.It is about 0.2 micron particle that such filter can hinder diameter.Can hold back about particle of 40% to 70% thus and until 80% phenols.Extra active carbon filter is held back the gaseous component until 85%.
The invention summary
But have the demand to the tobacco product filter that substitutes, it can have improved filtration.
This demand is through according to the tobacco product filter of independent claims, is used for removing the method for harmful substance and the purposes of tobacco product filter solves from tobacco smoke.Other exemplary embodiment is described in the dependent claims to some extent.
According to an illustrative aspects of the present invention, the filter of the tobacco product with carrier material is provided, said carrier material comprises immobilized ionic liquid.The notion of " tobacco product filter " is interpreted as being applicable to all or part of all types of filters of from tobacco smoke, removing harmful substance, particle, gas etc.Said tobacco product filter is particularly useful for constituting cigarette filter, cigarlet filter and tobacco pipe filter.Should also be noted that the concept and range of " tobacco " is very wide and should comprise the material that all can be taken out.
According to an illustrative aspects; Be provided for from tobacco smoke, removing the method for harmful substance; Wherein said method comprises provides the tobacco product of the illustrative aspects according to the present invention filter, and guiding tobacco product smog is through said tobacco product filter.
Said harmful substance can utilize ionic liquid from tobacco smoke, to remove or extract by physics mode especially.Said physics extracts and the difference of chemical extraction is that harmful substance is combined on the for example ion liquid cation or crystal structure in the chemical extraction process, for example on the cation of zeolite.
According to an illustrative aspects of the present invention, the said purposes that the filter that comprises immobilized ion liquid carrier material is used for removing from tobacco product smog harmful substance that has is provided.
The notion of " immobilization " is interpreted as gathering on carrier structure or carrier material especially.Said gathering especially distinguished with the fixedly introducing when constructing crystal structure mutually.This fixedly introducing for example as the cation of zeolite, in general utilize ionic bond to accomplish, and said gathering can also be passed through other power, and for example Van der Waals force is accomplished.Generally speaking, be immobilized in and be interpreted as not being the fixedly introducing in the crystal structure on the application's meaning.
Ionic liquid is at the document of generally acknowledging (Wasserscheid for example, Peter; Welton, Tom (Eds.); " Ionic Liquids in Synthesis ", Verlag Wiley-VCH 2003; ISBN 3-527-30515-7; Rogers, Robin D.; Seddon, Kenneth R. (Eds.); ,, Ionic Liquids-Industrial Applications to Green Chemistry ", ACS Symposium Series 818,2002; Be liquid organic salt or the salt mixture of being made up of organic cation and organic or inorganic anion on the meaning that ISBN 0841237891 "), fusing point is lower than 100 ℃.In said salt, can extraly be dissolved with inorganic salts, also have the molecule auxiliary agent in addition.On the application's meaning, the fusing point limit of arbitrarily confirming as 100 ℃ is interpreted as the ionic liquid on the wideer meaning, therefore comprises that also fusing point surpasses 100 ℃, but is lower than 200 ℃ ionic liquid.They other characteristic is as broad as long.
Ionic liquid has makes us interested characteristic especially, for example low-down near vapour pressure, very large liquefaction line (Liquidusbereich), good electrical conductivity and the unusual solvation characteristic that can not perceive.These characteristics make it can be used in various technical applications.Therefore can be for example (organic and inorganic when synthetic, transition metal-catalyzed, living things catalysis is during phase transfer catalysis (PTC), during heterogeneous reaction as solvent; In photochemistry, polymer synthetic with nanosecond science and technology in), as extractant (when liquid-liquid extracts with liquid-gas extraction, during oil desulfurization, when from waste water, removing heavy metal; When liquid film extracts), as electrolyte (in battery, in the fuel cell, in the capacitor, in the solar cell; In the sensor, in electrochemistry, in the electroplating technology, in the processing of electrochemistry metal; During electrochemistry is synthetic, in the nanometer technology), as lubricant, as hot fluid (thermofluide); As gel, as the reagent that is used for organic synthesis, in " Green Chemistry " (replacement VOC), as antistatic additive; In the special applications of analyzing (gas-chromatography, mass spectrum, Capillary Electrophoresis), as (not listing fully) such as liquid crystal.This for example consults following document: " Rogers, Robin D.; Seddon, Kenneth R. (Eds.); Ionic Liquids-Industrial Applications to Green Chemistry, ACS Symposium Series 818,2002; ISBN 0841237891 " and " Wasserscheid, Peter; Welton, Tom (Eds.); Ionic Liquids in Synthesis, Verlag Wiley-VCH 2003; ISBN 3527305157 ".
In addition, ionic liquid demonstrates outstanding characteristic as liquid or extractant, is used for polymer, biopolymer (for example cellulose, chitin), living beings (timber for example; Also have cellulose+lignin, also have polyphenol, protein); Metal in the aqueous solution for example; Gas is CO2 for example, and NOx, polar organic compound be alcohol, carboxylic acid, ether, ester, ketone and amine, aromatic hydrocarbon etc. for example.For example see WO2003029329, " Ionic liquids for aromatic extraction:Are they ready? " Anjan, Sachin; Chemical Engineering Progress (2006), 102 (12), 30-39, Chitin and chitosan dissolved in ionic liquids as reversible sorbents Of CO2.“Xie，Haibo；Zhang，Suobo；Li，Shenghai.Green?Chemistry(2006)，8(7)，630-633，Wood?liquefaction?by?ionic?liquids.”。Honglu, Xie; Tiejun, ShL; Holzforschung (2006), 60 (5), 509-512 with " Ionic liquids as extraction solvents:where do we stand? ", Dietz, Mark L.; Separation Science and Technology (2006), 41 (10), 2047-2063.
To the optimization of the ionic liquid characteristic of various application in the wide region, to accomplish through the combination that changes anion and cationic structure or change them, ionic liquid is introduced the address of " designer's solvent " usually and (is seen for example Freemantle, M.; Chem.Eng.News, 78,2000,37).
