Abstract
The invention discloses an application of a halogenated alkylimidazolium ionic liquid as a cigarette filter additive. The halogenated alkylimidazolium ionic liquid adopts chlorinated 3-propyl (diethoxymethylsilane)-1-methylimidazole or chlorinated 1-methyl-3-buthylimidazole or dibrominated 1,6-bis3-(1-methylimidazole). The invention further discloses a cigarette filter capable of selectively reducing the content of aromatic phenols in smoke, and the halogenated alkylimidazolium ionic liquid is added to the cigarette filter. According to the application, the content of ingredients such as tar, CO, phenol, crotonaldehyde and the like in the cigarette smoke can be reduced, and especially the effect of reduction of the aromatic phenols content is quite remarkable, so that the harm of smoking to human health is reduced greatly.
Description
Technical field
The present invention relates to cigarette filter, especially can the cigarette filter of fragrant phenol content in selective reduction flue gas, the invention still further relates to the purposes of halogenated alkyl glyoxaline ion liquid as cigarette filter-tip additive agent.
Background technology
Large quantity research shows that smoking and some diseases have the positive correlation determined, in order to reduce the harm of smoking to human body, a large amount of scientific worker have carried out studying very widely to the method reducing cigarette harm from different perspectives both at home and abroad.Fragrance phenol is can to one of material that health works the mischief in flue gas, and it has inhibitory action to central nervous system, the toxic chemical substance of energy loss victimization body Liver and kidney function.After phenol enters human body, also can be oxidized into the larger hydroquinones of toxicity and catechol.Countries tobacco administrative department recent by one of phenol priority target being classified as cigarette harm-reducing.
In order to reduce the fragrant phenol in cigarette smoke, the method for selection is can be used for generally to have following two kinds.One is start with from source, by reducing the fragrant phenol produced in cigarette burning process, reduces the fragrant phenol content in flue gas.Existing research report proves at present, under the condition of simulated combustion, by the sugar that reduces in pipe tobacco or add specific catalyst can reduce in cigarette burning process the fragrant phenol produced to a certain extent in cigarette, but, the technical process relative complex involved by the method, the impact of taste inhaled on cigarette be difficult to hold.Another method is then the terminal at cigarette, utilizes the sorbing material specific components removed in flue gas to reach and falls harmful object.The advantage of adopting in this way be selective sorbing material more, be easy to implement aborning.But, because common commercial adsorbent does not have optionally adsorption capacity to fragrant phenol, be difficult to avoid sorbing material focusing wet goods and the strong adsorption of inhaling the closely related component of taste, must have a negative impact to cigarette odor-absorbing, as can be seen here, current material cannot meet the object of fragrant phenol content in selective reduction flue gas.
Summary of the invention
An object of the present invention is to provide one and can reduce harmful constituents in cigarette flue gas, especially can fragrant phenol content and do not change cigarette style and inhale the cigarette filter of taste in selective reduction flue gas.
Halogenated alkyl glyoxaline ion liquid is with the addition of in cigarette filter provided by the present invention.
Preferably, described halogenated alkyl glyoxaline ion liquid is chlorination 3-propyl group (methyldiethoxysilane)-1-methylimidazole or chloridization 1-methyl-3-butyl imidazole or the two 3-(1-methylimidazole) of dibrominated 1,6-.Its structural formula is respectively such as formula shown in I, II, III.
Further preferably, the addition of described halogenated alkyl glyoxaline ion liquid in cigarette filter is that 1 ~ 1.5mg/ props up.
Second object of the present invention is to provide the preparation method of the cigarette filter of fragrant phenol content in a kind of energy selective reduction flue gas, the method is: be dissolved in by halogenated alkyl glyoxaline ion liquid in plasticizer triacetyl glycerine, directly be sprayed in filter stick in filter stick wire-beam forming process, described halogenated alkyl glyoxaline ion liquid accounts for 5 ~ 20% of triacetyl glycerine weight, and the addition of described halogenated alkyl glyoxaline ion liquid in cigarette filter is that 1 ~ 1.5mg/ props up.
3rd object of the present invention is to provide the purposes of halogenated alkyl glyoxaline ion liquid as cigarette filter-tip additive agent.
The invention has the beneficial effects as follows:
Halogenated alkyl glyoxaline ion liquid provided by the present invention has the effect of strong hydrogen bonding alkalescence, dipole effect and lower dispersion force effect in separation process, the compound of the larger polarity of energy selective absorption, after being added to cigarette filter, the equal decrease to some degree of content of the compositions such as the tar in cigarette smoke, CO, phenol, crotonaldehyde, especially reduce the effect highly significant of fragrant phenol content, thus greatly reduce the harm that smoking causes health.Ionic liquid can not have any impact with suction taste to the style of cigarette adding in mouth rod simultaneously.
