BACKGROUND OF THE INVENTION

1. The technical field to which the invention relates.

The present invention relates to a smoking article containing a filter element and / or smoking material containing a highly structured mesoporous molecular sieve, and more specifically, to a smoking article containing a filtering element and / or smoking material containing highly porous amorphous silicon dioxide (hereinafter referred to in this definition, as "MSM-41") as a highly structured mesoporous molecular sieve for filtering out the vapor phase components contained in the mainstream smoke .

2. The level of technology

Typical smoking articles, such as cigarettes, comprise a cylindrical filter element located on one axis with a cylindrical rod filled with tobacco. The filter element and even the tobacco-filled rod include various materials that remove certain components from the mainstream smoke. Often these materials are non-selective, and therefore remove components that should not be removed from the main stream of smoke and lead to an undesirable taste.

Some cigarettes contain filter elements that include materials such as coal. Typical cigarettes and filters are described in US Patent Pub. No.2003 / 0159703 issued by Yang, et al., And US Patent Pub. No.2003 / 0154993 issued by Paine, III et al. Typically, the surface area is inversely proportional to the size of the coal particles. If the particle size is too large, then the surface area may not be sufficient to carry out the necessary filtration. This factor must be carefully considered when choosing a specific particle size of coal. In addition, filter elements that contain charcoal often give a metallic taste while smoking. In an attempt to mask the metallic taste, the coal is often impregnated with a flavor that can clog pores and impede filtration and determining the preferred flavor is difficult and inefficient. In addition, filter elements that contain carbon differ in the ratio of the number of micropores to the number of mesopores, the term “microporous” usually refers to such materials having a pore size of about 20 Å or less, and the term “mesoporous” usually refers to such materials having a pore size of about 20-500 Å. A uniform pore size distribution is preferred. In the case of a more uniform pore size distribution, it can be guaranteed that a larger number of pores will belong to the mesoporosity range (2-50 nm), which provides a more efficient smoke filtration than when using microporous materials. In the case of pores of different sizes, filtering off of various compounds is more likely and filters intended for specific analytes are more desirable.

A smoking article is required with a filter element capable of filtering out the vapor phase components, which is cost-effective to manufacture and does not impart a metallic taste.

SUMMARY OF THE INVENTION

Due to the known difficulties associated with the filter elements of previous smoking articles, a smoking article with a mesoporous molecular sieve has been developed for filtering out the vapor phase components contained in the main stream of tobacco smoke.

According to the invention, it was found that a group of highly ordered mesoporous molecular sieves manufactured by Mobil Corporation, designated as M41S, is applicable to filter elements of a smoking article. M41S materials are non-crystalline silicon dioxide, collected using a matrix of a surfactant, with a narrow pore size distribution. MCM-41 is a highly porous silica gel, assembled using a matrix of a surfactant, belonging to the M41S group and comprising a highly ordered hexagonal system of homogeneous pores with adjustable diameters from about 15 to about 100 Å. The term "hexagonal" includes materials that have mathematically rigorous hexagonal symmetry, and materials with significant observable deviations from ideality. MSM stands for Mobil Composition of Matter (composition manufactured by Mobil) or Mobil Crystalline Material (crystalline material manufactured by Mobil) and is developed by Mobil as a support for catalysts.

The surface of the silicon-containing MCM-41 includes silanol groups (SiOH), which can be synthesized using cetyltrimethylammonium chloride (CTAHL), H ₂ O, Na ₂ O and SiO ₂ . The obtained MCM-41 can be used as a mesoporous molecular sieve in smoking articles. MCM-41 has a highly condensed surface containing fewer SiOH groups than silicon dioxide, and its peculiarity is the shape that it acquires around the matrix, which is then removed. The use of mesopores for absorption is described in US Patent No.5580370. issued by Kuma, et al. In addition, the MCM-41 has a large surface area and for it the BET surface area is approximately 1000 m ² / g, therefore it has a large sorption capacity. (“BET” means Brunauer, Emett, and Teller, three scientists who optimized the theory of measuring surface area). MCM-41 is effective in reducing the content of alcohols, aldehydes, ketones, nitriles and naphthalene.

The object of the present invention is a smoking article with a filter element containing a mesoporous molecular sieve, MCM-41. A preferred smoking article is a cigarette containing MCM-41 located in the filter element.

Another object is a smoking material in a smoking rod of a smoking article containing a mesoporous molecular sieve, MCM-41. The preferred smoking article is a cigarette and the preferred smoking material is tobacco. In this embodiment, the MCM-41 is located in the smoking material in the core.

Another object is a filter element and smoking material in a smoking rod of a smoking article, each of which contains a mesoporous molecular sieve, MCM-41. In this embodiment, the MCM-41 is located in the filter element and in the entire smoking material in the rod.

Another object is a filter element and / or smoking material in a smoking rod of a smoking article containing a mesoporous molecular sieve, MCM-41, in combination with charcoal and / or ion exchange resin.

Another object is a filter element and / or smoking material in a smoking rod of a smoking article containing an impregnated mesoporous molecular sieve, MCM-41. Copper oxide can be included in MCM-41 to better remove HCN and H ₂ S.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Although a wide variety of embodiments are possible for the present invention and the preferred embodiments of the present invention are presented and will be described in detail below, the present description should be considered as containing examples of the principles underlying the present invention, and not as limiting the general objects of the present invention to the illustrated variants implementation.

The present invention relates to a smoking article comprising a mesoporous molecular sieve, MCM-41, for filtering vapor phase components from a mainstream smoke stream. The components of the vapor phase that must be filtered, interact with the MCM-41 and are retained in the pores, thereby separating unwanted components from the rest of the vapor. MCM-41 is usually a black or white granular material having a density of ≈0.3 g / cm ³ and a BET surface area of ≈1000 m ² / g. Although the pore wall thickness may vary, MCM-41 typically has uniform pore diameters of ≈3.7 nm when cetyltrimethylammonium bromide is used.

The following examples are provided for illustration only and are not intended to limit the scope of the present invention.

Example 1

Adsorption characteristics of MCM-41

To determine the adsorption characteristics of the MCM-41, it is examined in hand-made chamber filters and a comparison is made with semoline (inert flour granules used to simulate a chamber filled with granules). Chamber filters can be made manually by first removing the cellulose acetate (AC) filter of the cigarette. The shortened AC segments at the end of the cigarette filter facing the mouth form a chamber for holding the granular material.

Sets of samples MCM-41 were obtained by the usual method of synthesis with slight changes. MCM-41 was developed by Exxon / Mobil, but sets of samples for experiments were developed in the laboratory. Water, the surfactant cetyltrimethylammonium bromide (CTAB) and terraethylorthosilicate (TEOS) were successively mixed in a 250 ml glass vial until a cloudy white suspension formed. CTAB and TEOS were combined in a molar ratio of surfactant: silica equal to 1: 2. The concentration of surfactant in solution in terms of the total mass was 25%. Concentrated sulfuric acid was added dropwise until the mixture turned into a clear liquid. The solution was stirred at approximately 400 rpm for 0.5 h and then autoclaved under static conditions (121 ° C, 18 lbf / in) for 1 h. The resulting gel was removed from the autoclave and cooled, and then thoroughly washed with deionized water. The washed material was heated in air at 570 ° C for 6–8 h and a porous material was obtained having a BET surface area of ≈1300 m ² / g.

Sets of cigarette samples containing 50 mg of a granular additive in a hand-made chamber filter were prepared using either MCM-41 synthesized as described above or semolines. For each set of samples, a pressure differential is set so as to reduce the variation in smoke emission. The samples were conditioned (at a relative humidity of 65% and 75 ° C for 48 h) and the analysis determined the total amount of vapor phase (PVPF), HCN content in the mainstream smoke (HSD) and carbonyl compounds in the HFS.

For cigarettes with chambers containing 50 mg of semolina or MCM-41, smoke released from PVPF was analyzed. Table A shows the data for some compounds contained in the vapor phase of the smoke and compares the semolina with MCM-41:

TABLE A.
Smoke Vapor Analysis Data (μg / cigarette) Analyte Semolina (50 mg / mouthpiece) MSM-41 (50 mg / mouthpiece) Hydrogen sulfide 21.0 22.3 Hydrogen cyanide 76,4 68.1 Methanol 79.5 30,4 Acetaldehyde 647.0 536.1 Vinyl chloride 0,0 0,0 1,3-butadiene 55.6 54,2 Acetonitrile 69.6 33.6 Propylene oxide 2.9 1.8 Acrolein 82.0 45.8 Furan 27.9 22.4 Propionic Aldehyde 62.7 33.3 Acetone 228.5 91.1 Acrylonitrile 10.3 6.0 Carbon disulphide 3.8 4.0 Isoprene 396.4 371.5 Propionitrile 11.6 4,5 Isobutyric Aldehyde 18.1 10.0 Methacrylonitrile 2.2 1,2 n-butyric aldehyde 6.5 3,5 Methyl ethyl ketone 48.3 15.0 Crotonic aldehyde 12.6 6.8 Benzene 35.1 33.3 Toluene 35.1 28.1 Styrene 3.0 1.3 Total PVPF 1936.1 1424.3 PTC (mg / cigarette) 13.1 12.7 PVPF / PTC (μg / mg) 147.8 112.1

MSM-41 led to a more significant decrease in the content of the analytes with a value of PVPF / PTC equal to 112.1 μg / mg. In the case of semoline, the value of PVPF / PTC was large (147.8 μg / mg).

Figure 1 shows the percentage expressed and normalized to the total amount of solid particles (PTC) reduction in the content of various components of the vapor phase. These data show that the MCM-41 sample is more effective at filtering out nitriles, ketones, and aldehydes than the control sample of semolina. A large decrease in the content of the analyzed substances propionitrile (58%), methanol (59%), methyl ethyl ketone (66%) and propionic aldehyde (43%) was found. In general, when using MSM-41, the content in PVPF decreased by 24%.

The content of carbonyl compounds in the mainstream smoke (HDM) after the use of semolina and MCM-41 are compared in Table B:

TABLE B.
The content of carbonyl compounds in GDM (μg / cigarette) Analyte Semolina (50 mg / mouthpiece) MSM-41 (50 mg / mouthpiece) Acetaldehyde 701.7 444.8 Acetone 276.4 72,4 Acrolein 115.1 46.2 Butanon 84.6 17.9 Butyraldehyde 45.8 14.1 Crotonic aldehyde 28.0 10.9 Formaldehyde 55.7 34,4 Propionic Aldehyde 58.2 24.5 Total (mcg) 1366.0 664.0 PTC (mg / cigarette) 13.1 12.7 Total / PTT (μg / mg) 104.3 52.3

MCM-41 resulted in a lower content of carbonyl compounds in the mainstream smoke than semoline: 52.3 μg / mg and 104.3 μg / mg, respectively. Expressed as a percentage and normalized to the PTD, the decrease in the content of carbonyl compounds in the mainstream smoke is shown in FIG. 2. The data show that the MCM-41 sample has a more significant affinity for the carbonyl compounds contained in the HDM than the control sample of semoline. Sample MCM-41 reduced the content of carbonyl compounds in the mainstream smoke by 49% compared to the semolina sample. For the analyzed substances, acrolein, acetone, butanone, and butyric aldehyde, according to the calculations of MCM-41, reduced the content by more than 50% compared to the control. The measured formaldehyde content decreased by 34% compared with the use of semolina.

Table C summarizes the average content of polycyclic aromatic hydrocarbons (PAHs) in the solid smoke phase:

TABLE C.
The average PAH content for cigarette samples Semolina MSM-41 Naphthalene 365.6 284.5 Fluoren 127.2 134.9 Phenanthrene 103,4 113.7 Anthracene 40.3 43.6 Fluorantent 58.7 61.5 Pyrene 38,4 39.1 Benzofluoren 30.3 32,0 Benzanthracene 16.8 17,2 Chrysen 17,2 18.2 Benzofluoranthene 7.0 7.3 Benzo [e] pyrene 3,7 3.8 Benzo [a] pyrene (BAP) 5.8 6.1 Perylene 0.6 0.7 Dibenzanthracene 0.2 0.2 Benzoperylene 1,1 1,2 Total PAH (ng / cigarette) 816.4 763.9 PTC (mg / cigarette) 11.3 11.8 Number of puffs 6.9 6.8 PAH in terms of PTC (ng / mg) 72.0 64.6 BAP in terms of PTC (ng / mg) 0.52 0.51

When comparing semolina with MSM-41, the values normalized to the total amount of solid particles (PTC) show that the naphthalene content is reduced by ≈29%. This effect may be due to the fact that naphthalene has the smallest molecule and is the most volatile of the PAHs studied and shows that MCM-41 has a high affinity for small molecules and volatile compounds. For all other PAHs studied, no markedly improved affinity was found for the MCM-41 sample compared to the control sample.

As a result, it was found that MCM-41 samples are effective adsorbents for selected components found in the mainstream smoke. A significant decrease in the content of nitriles, aldehydes and ketones was found. In addition, in the study of PAHs, a significant decrease in the naphthalene content was found. MCM-41 has an affinity for molecules that form strong intermolecular bonds and, therefore, a decrease in the content of analytes not detected is 1,3-butadiene, isoprene, furan and benzene. MSM-41 samples are more effective at filtering out nitriles, aldehydes and ketones than the control sample of semolina. In addition, MCM-41 detects selectivity for naphthalene.

Example 2

Comparison of MSM-41 with sorbitol as an additive to a cigarette filter

To determine the filtering efficiency for MSM-41, it is sorbitol, i.e. activated carbon obtained from semanthracite and manufactured by Calgon Carbons was placed in hand-made cigarettes with chamber filters, the characteristics of which are discussed above, and their filtering characteristics are compared. Semoline was used as a control. The highly porous structure of the MCM-41 prompted a comparison with activated carbon, such as sorbitol. Samples of MCM-41 were prepared according to the above procedure. Sorbitol was used without modification.

Three sets of samples were prepared using handmade cigarettes with chamber filters. Table D shows the filter additives and their contents for each sample.

TABLE D.
Filter Component Content Filter components Content (mg) MSM-41 / Semolina 50/50 Sorbitol / Semolina 50/50 Semolina as a control one hundred

For the samples, a pressure differential is set so as to reduce the change in aerosol emission. After conditioning, the samples determined the total amount of vapor phase (PVPF), the content of polycyclic aromatic hydrocarbons (PAHs) and carbonyl compounds in the mainstream smoke (HSD).

PVPF was investigated for all three samples. Table E shows the vapor phase contents after using each sample:

A direct comparison of vapor phase data for MCM-41 and sorbitol shows that although activated carbon is generally a good adsorbent for a wide range of analytes, MCM-41 is selective for more polar analytes, such as nitriles, aldehydes, ketones and alcohols. This affinity for polar molecules can be explained by its strong intermolecular binding to protruding hydroxy groups located on the surface of silicon dioxide, and FIG. 3 shows the selectivity of MCM-41.

For all three samples, the content of carbonyl compounds in the mainstream smoke was also determined and the results are shown in Table F:

TABLE F.
The content of carbonyl compounds in GDM (μg / cigarette) Semolina Sorbitol / Sem * MCM41 / Sem * Acetaldehyde 641.5 561.2 539.8 Acetone 256.7 164.2 104.9 Acrolein 106.7 64,4 67.4 Butanon 74.7 33.0 24.8 Butyraldehyde 40.8 19.8 18.5 Cretonaldehyde 27,2 16.7 11.6 Formaldehyde 51.8 43.6 40.1 Propionic Aldehyde 53.9 33.6 35.0 Total carbonyl compounds 1253.3 936.6 842.0 Total Carbonyl Compounds / PTC 99.5 73,2 67.4 * Sem = semolina

Table F compares the content of carbonyl compounds in the mainstream smoke after using semolina, sorbitol / semolina, and MCM-41 / semolina. MCM-41 leads to a total carbonyl content of 842.0 μg / cigarette, and sorbitol passes a greater amount of carbonyl compounds: 936.6 μg / cigarette. Figure 4 shows the percentage and normalized decreases in the content of carbonyl compounds in the mainstream smoke after using MCM-41 and sorbitol. These results are consistent with vapor phase analyzes. The decreases observed for silica collected from a surfactant matrix were (at least) comparable to those for sorbitol samples. For some analytes, such as acetone and crotonaldehyde, the reductions were more significant.

Since a decrease in the naphthalene content is observed when using MSM-41 samples, the content of polycyclic aromatic hydrocarbons (PAHs) was also studied. Table G provides a complete list of research results for PAHs:

Polycyclic Aromatic Hydrocarbon (PAH) Analysis Data (μg / cigarette) PAH - FTC Semolina Sorbitol / Sem MCM41 / Sem Anthracene 40.8 41,4 42.1 Benzanthracene 16,4 16.9 17,2 Benzo [a] pyrene 6.2 6.2 6.2 Benzo [e] pyrene 4.4 4.6 4,5 Benzofluoranthene 7.4 7.5 7.4 Benzofluoren 28.5 28.7 30.6 Benzoperylene 1,2 1,2 1,2 Chrysen 18.8 19.0 19,4 Dibenzanthracene 0.2 0.2 0.2 Fluorantent 47.0 45.8 49.4 Fluoren 130.0 126.0 131.5 Naphthalene 453.0 198.0 271.0 Perylene 0.6 0.6 0.6 Phenanthrene 111.0 110.5 111.0 Pyrene 39.5 39.0 39.9 PAH PTCH 13.3 12.7 13,2 Total PAHs 904.9 645.3 732.0 Total PAH / PTCH 68.3 50.7 55,4

The decrease in the naphthalene content normalized to the total amount of solid particles (PTC) compared to the control (semolina) for MSM-41 was ≈40% and for sorbitol was ≈54%. A decrease in the content of other PAHs was not observed. Although naphthalene has the smallest molecule and is the most volatile of the PAHs studied, a decrease in the content of naphthalene is apparently due to its volatility, and not the size of the molecule. The pore diameter of MCM-41 is large compared to the size of the anthracene molecule, the next largest analyte to be studied by the size of the molecule, for which no decrease in content was detected. These data characterize the ability of sorbitol to adsorb nonpolar molecules.

As a result, it was found that MCM-41 samples are more selective with respect to the polar components of smoke and are superior to sorbitol when removing nitriles, ketones, alcohols, and aldehydes. A sorbitol sample was more effective against non-polar smoke components such as benzene, toluene, styrene, isoprene and naphthalene. MCM-41 can complement sorbitol and other additives, such as ion exchange resins, when used as an auxiliary additive.

Example 3

MCM-41 with inclusion of copper oxide

Sample MCM-41 was prepared according to the procedure described in example 1. When preparing MCM-41, copper (II) nitrate was additionally introduced into the solution of the reaction mixture at a concentration of 3%. The resulting gel was calcined at 400 ° С and MCM-41 was obtained with the inclusion of copper oxide having the same large surface area and the ability to absorb the vapor phase as pure MCM-41, but additionally having the ability to reduce the content of hydrogen cyanide and hydrogen sulfide. Compared to semolina, as a control sample, MCM-41 with the inclusion of copper oxide resulted in a 56% reduction in HCN and a 35% decrease in H ₂ S.

The above detailed description is provided primarily to improve understanding and it should be understood that it does not impose unnecessary restrictions on changes that should be obvious to specialists in this field of technology after reading this description and which can be made without deviating from the essence of the present invention and the scope of the attached claims.
