10 Levels of Technology

It is known that tobacco smoke contains, in addition to nicotine, aldehydes, benzopyrene and tar, having a cancer-causing effect. Therefore, cigar manufacturers will constantly reduce the quantity of smiles and other

15 foreign substances that come with tobacco smoke into the lungs. The filters offered for this purpose are very diverse, and all of them are contained in the main component of the product, which is most susceptible to the incidence of

20 filters containing an activated carbon component. Of the many patent documents relating to smoke filters containing a coal smoke, it is possible to mention, for example, patent 2413. Α 24 0 3/16, May 29, 1981. Smoke filter,

25 Sprayed in the indicated patent, it protects part of the foreign substances from tobacco smoke, as well as nitrous oxide, nicotine, 3, 4-benzopyrene, and aromatic. Nevertheless, it is desirable to increase the efficiency of coal filters. It is also advisable not to increase or

30 to even reduce the pressure drop across the filter, which should be quick to pull and pull, pulling it for a short time will cause the pressure to pull off Unsatisfactory, short-circuited make the puller tighten more and more often.

Thus, the task of the invention is to further increase the efficiency of the smoke filter 5, containing a carbon-containing material.

SUMMARY OF THE INVENTION In order to solve the above problem, the present invention provides a cigarette filter material that contains a high mixture of carbon dioxide.

10 facilities, including the carbon dioxide of the C ₆ and the carbon dioxide C ₃ , C ₄ , C ₅ . The indicated carbon mixture may be obtained in different ways. Β Particularly, the indicated carbon mixture may be obtained by a clean heating mixture.

15 products and acids, as in

Russian Patent 2128624, CL С01Β 31/04, 04/10/1999, included in the present description by reference.

When such a heating occurs between a group of scales, a large number of electrical discharges occur,

Not wanting to be bound by theory, I propose

25th of this mixture possesses a very high reactive welfare, thanks to the fact that it is obtained from the charcoal free process.

30 The indicated carbon mixture is exceptionally suitable for inclusion in traditional materials of cigarette filters, such as paper or cellulose acetate materials, and also in the quality of a separate component of the cigar filter. Due to its structure, the particles of the carbon mixture exhibit a good clutch with the carrier material. Previously, including the inclusion of 5 activated charcoal in cigarette filters, there was such a problem when pulling small coal particles away from the filter. For the most part of the indicated carbon mixture, the primary mixture is retained by a paper or acetate cellulose,

10 this avoids the intentional problems in the filters that contain the material of the invention. In addition, the indicated carbon mixture does not add up to the filter and, therefore, does not complicate the delay.

15 In addition, it follows also that the indicated carbon mixture is harmless to humans and is environmentally friendly.

Efficiency of filtering tobacco smoke by the material containing the invention

20 carbon mixture, was tested on a cigarette with a coal filter "President".

Tobacco smoke from smoked cigarettes was emitted through a system of absorbers filled with hexane. The speed of smoking one cigarette was 3-4

25 minutes. Βyκuρivali sigaρeτy τρeχ gρuππ: remote φilτροm, sο sτandaρτnym ugοlnym φilτροm and sigaρeτy with κοmbiniροvannym φilτροm and imennο in κοτορyχ ugοlny κοmποnenτ sτandaρτnοgο φilτρa it was removed and vmesτο negο isποlzοvalas uκazannaya ugleροdnaya mixture vzyaτaya

30 in the amount of 30 mg per cigarette and placed in a glass mouthpiece.

The customer system has two inquiries

The combined Zaitsev absorber with 3 ml of hexane each.

In the process of smoke emission through the system of absorbers, the Hexane exhaustively extinguishes in yellow. The potency was 5 the highest for the cigarette from the filter and the smallest for the cigarette;

After a 4-5 quick wash of hexane, a combined after smoking a cigarette with a combined filter,

10, a fluorescence pattern was obtained with an average of 3,4-benzopyrene, a concentration of hexane in Hexane amounted to only 3 nanograms per 1 ml. In the case of a cigarette without a filter and with a standard coal filter, the content of 3, 4-benzene was rather high, so that it wasn’t

15 I have removed the quantitative method of EZhZh (ZHC) with a fumigation.

To determine the efficiency of the filters, we also examined the combined extracts of the extracts. These extracts diluted water to a volume of 25 ml, and then

20 were obtained for the UF spectrum in the region of 220-350 nm. A peak at 260 nm was used to determine the presence of aromatic hydrocarbons in the product, and intensive absorption was used for the absorption of products. Β The results of these studies have been established,

25 that the standard coal filter saves about 80% of the aromatic substances, while the combined filter containing the material is 90%.

Otherwise, the replacement of the coal component with the standard coal filter does not replace the carbon mixture.

30 increased the efficiency of the filter, while the efficiency of the filter increased by half. Although an embodiment of the invention is illustrated in the art, a specific embodiment of this invention will show a variety of non-hazardous products.

5 of the present invention.
