The inventor finds, under adsorbent and the situation with active carbon and silica/alumina as cigarette filter, can remove special component in the mainstream smoke especially by these cooperative effects, thereby finish the present invention.
In the present invention, as filtering material, can use acetic acid esters, paper, nonwoven etc.As the active carbon in the adsorbent, can use common coconut slag (ャ シ ガ ラ) active carbon etc.As the silica/alumina in the adsorbent, for example, can use by consonance chemical industry production with the commercially available silica/alumina of キ ヨ-ヮ-De/700SN as trade name.This product, SiO 2Content is 63.0wt%, Al 2O 3Content is 10.3wt%, and dried reduction is 14.5wt%.
In the present invention, under the situation that contains adsorbent in the filtering material, active carbon and silica/alumina amount are drafted in the adsorbent total amount for every 10mm filtering material and are contained 1mg-150mg, be preferably 20mg-60mg, when containing in the space between the filtering material under the situation of adsorbent, draft in the adsorbent total amount for every 5mm space and contain 5mg-300mg, be preferably 30mg-120mg.
Below, embodiments of the invention are described.
Make the cigarette filter of benchmark (contrast) (no adsorbent) in contrast as follows.Prepare 2 acetic acid esters and be formed into the filtering material (common filter tip) of length 10mm, thereby coil paper forms 2 filter tip parts on rolling up around each filtering material silk size 2.2 Brittanies that, fibre bundle fiber number 40000 Brittanies that.The space of 5mm is set between 2 filtering materials, does not fill adsorbent in this space, paper formalizes on volume around 2 filter tip parts.This filter-tip aeration resistance is 80mmH 2O (1050mL/min).
In Fig. 1, represented a example according to the cigarette filter of the present invention's making.This cigarette filter is made according to following process.Prepare 2 acetic acid esters and be formed into the filtering material (common filter tip) 2 of length 10mm, thereby coil paper 3 forms 2 filter tip parts on volume around each filtering material 2 silk size 2.2 Brittanies that, fibre bundle fiber number 40000 Brittanies that.2 of 2 filtering materials the space is set, in this space, fill silica/alumina as the 30mg active carbon 41 and the 30mg of adsorbent 4 (42 the mixture of trade name キ ヨ-ヮ-De/700SN), under this state, setting paper 5 on volume around 2 filter tip parts.At this moment, regulate the space so that the appearance density of adsorbent is 100%.
In order to compare, make being filled with as the 30mg active carbon of adsorbent separately or being filled with the cigarette filter of 30mg silica/alumina separately.
In addition, double the adsorbent consumption, make the cigarette filter of filling the 60mg active carbon separately or filling the 60mg silica/alumina separately.
With paper tape above cigarette filter is connected to the cigarette position of going up tobacco leaf with the coil paper volume, as shown in table 1, make the various experiments of different adsorbents and use cigarette.At cigarette part commodity in use cigarette.About these cigarettes, carry out the absorption experiment of mainstream smoke according to following process.
Connect cigarette and automatic smoking apparatus by flexible pipe ( ィ go Application system).Do not put into Cambridge (ケ Application Block リ ッ ジ) filter tip.Burning length is set at 40mm, under standard smoking condition, cigarette is carried out smoking by automatic smoking apparatus.By the smoking exhaust outlet, in the air bag that adds He in advance (テ De ラ-system), absorb mainstream smoke, regulate so that cumulative volume is 8 liters with He.The 50mL gas that from this air bag, collects by gc analysis.
As the special component in the mainstream smoke, be mainly pyrazine class, phenol, hydrocarbon, ketone etc., carry out data analysis based on the peak area of the special component on the gas chromatogram.In table 1, represented the penetrance of pyrazine class and phenol.The peak area note of the special component on the gas chromatogram when will not have adsorbent (contrast) is made the peak area of the special component on A cnt, the gas chromatogram in the time of will using adsorbent a and is remembered that when making Aa, the penetrance Ta of these special components uses
Ta=Aa/A cnt represents.Measured value of experiment in the table 1 is based on that the peak area of the special component on the gas chromatogram tries to achieve.
In addition, using the predicted value of the filter-tip penetrance of 60mg active carbon is to use the measured value of experiment of the filter-tip penetrance of 30mg active carbon to multiply by 2 values that obtain.Equally, use the predicted value of the filter-tip penetrance of 60mg silica/alumina to be to use the measured value of experiment of the filter-tip penetrance of 30mg silica/alumina to multiply by 2 values that obtain.
On the other hand, be to predict the calculated value of the penetrance that obtains by the penetrance of independent separately adsorbent in table 1 and with the predicted value of the penetrance during adsorbent more than 2 kinds.That is, the penetrance of special component (measured value of experiment) note is made Ta in the time will using adsorbent a, the penetrance (measured value of experiment) of special component is remembered when making Tb in the time of will using adsorbent b, predicted value (Ta * Tb) expression.
Yet, and if the measured value of experiment of the penetrance during with 2 above adsorbents significantly littler than predicted value, can judge and adsorb those special components especially and shown cooperative effect by the adsorbent more than 2 kinds.In table 1, put down in writing above result jointly.
Table 1
Adsorbent Penetrance
The pyrazine class Phenol
Measured value Predicted value Measured value Predicted value
Do not have ??1.00 ??1.00
Active carbon (30mg) ??0.60 ??0.68
Silica/alumina (30mg) ??0.73 ??0.61
Active carbon (60mg) ??0.38 ??0.36 ??0.48 ??0.46
Silica/alumina (60mg) ??0.54 ??0.53 ??0.38 ??0.37
The mixture of active carbon (30mg)+silica/alumina (30mg) (amounting to 60mg) ? ??0.22 ? ??0.44 ? ??0.30 ? ??0.41
When the consumption that makes independent active carbon is that original 2 times situation or the consumption that makes independent silica/alumina are under the original 2 times situation, almost there is not difference between measured value and the predicted value.
In addition, though in table 1, do not demonstrate, thereby utilize the measured value of hydrocarbon and ketone and the difference between predicted value very little can not confirm by and with the cooperative effect of adsorbent more than 2 kinds.
Comparatively speaking, as shown in table 1, measured value for pyrazine class and phenol is littler than predicted value, shown by and be used as the active carbon of adsorbent and the cooperative effect of silica/alumina, known that this filter tip has adsorbed these special components especially.
Can know from above result, thereby if use separately active carbon or silica/alumina effectively absorption be called the special component of pyrazine class and phenol, then essentially further increase the adsorbent consumption, and then can have a significant impact fragrance.Comparatively speaking, when and be used as under the situation of the active carbon of adsorbent and silica/alumina, use a small amount of adsorbent also can effectively adsorb the special component that is called pyrazine class and phenol even can envision, also little for the influence of fragrance.
