    The invention relates to a method for preparing an additive for smoking tobacco or a filter element, wherein the additive consists of various metal oxides.
    and / or hydrates of metal oxides with a large specific surface.

If such combinations of metal oxides and / or gi Drates of metal oxides are obtained by mixing. shake and so on, then from comp. No homogeneous mixture is formed. This heterogeneity (inhomogeneity) is manifested in the adhesion of individual particles and in the formation of lumps. Lumps of particles of metal oxides and / or hydrates of metal oxides cause poor flowability, dispersibility and spreadability of the mixture, which makes it difficult to add several metal oxides and / or hydrates of metal oxides together to smoking products and their filter elements. This results in an uneven distribution of the additive on / or in the base materials from which these smoking tobacco products or filter elements are made. There is also known a method for preparing an additive for smoking tobacco or filter elements by mixing the following metal oxides and / or metal oxide hydrates; silica (silicic acid) precipitated amorphous and aluminum oxide hydroxide (aluminum hydroxide) precipitated crystalline (gamma structure), or silica (silicic acid) pyrogene amorphous and alumina pyrogenic crystalline (partially delta structure, mainly gamma structure), or silicon dioxide silicic acid) precipitated amorphous on and silica (silicic acid) pyrogenic amorphous, nly dioxide. titanium pyrogenic crystalline (partially modified rutile, mainly anatas modification) and silica (silicic acid) pyrogen is amorphous, or silica (silicic acid) is pyrogenic amorphous and 1924 alumina hydrate (aluminum hydroxide) precipitated crystalline (gamma structure) or crystalline alumina (aluminum hydroxide) precipitated crystalline (gamma structure) or crystalline alumina (aluminum hydroxide) 19 silicon (silicic acid) precipitated amorphous and magnesium oxide calcined crystalline (cubic), or silicon dioxide (silicic acid) precipitated amorphous and calcium oxide calcined crypt tallic (cubic) or silica (silicic acid) precipitated amorphous and alumina monohydrate (A100H, boehmite), crystalline (gamma structure), or magnesium oxide, calcined crystalline (cubic) and alumina, calcined crystalline (gamma structure), or silica (silicic acid) pyrogenic amorphous and alumina monohydrate (A100H, be-, mit) crystalline (gamma-structure), or silicon dioxide (silicic acid) pyrogenic amorphous and alumina monohydrate (A100H, boehmite) cris tallic (gamma-structure), or silicon two-oxide (silicic acid) precipitated amorphous and titanium dioxide precipitated crystalline (anatas modification) 23. However, tobacco smoke with these additives is not sufficiently purified from harmful substances. The purpose of the invention is to improve the quality of cleaning tobacco smoke from harmful substances. The goal is achieved by the fact that according to the method of preparing an additive for smoking tobacco or filter elements by mixing the following metal oxides and / or metal oxide hydrates, - silica (silicic acid) precipitated amorphous and aluminum hydroxide (aluminum hydroxide) precipitated crystalline (gamma -structure), or silica (silicic acid) is pyrogenic amorphous and alumina is pyrogenic crystalline (partially delta-structure, mainly gamma-structure), or dioxide belts (silicic acid) precipitated amorphous and silica (silicic acid) pyrogenic amorphous, or titanium dioxide pyrogenic crystalline (partially modified rutile, mainly anatas modified) and silicon dioxide (silicic acid) pyrogenic amorphous, or silicon dioxide (silicic acid) pyrotechnic) silicon dioxide (silicic acid) pyrogenic amorphous, or silicon dioxide (silicic acid) pyrotechnic acid (silicic acid) pyrogenic amorphous, or silicon dioxide (silicic acid) pyrotechnic acid). on and alumina hydrate (aluminum hydroxide) precipitated crystalline (gamma structure) or silica (silicic acid) precipitated amorphous and magnesia calcined crystal or copper (silica), or silicon dioxide (cross-neva acid) precipitated amorphous and calcium oxide calcined. crystalline (cubic) or silicon dioxide (silicic acid precipitated amorphous and xyuminium oxide monohydrate (A100H, boehmite) crystalline (gamma structure), or magnesium oxide, calcined crystalline (cubic) and alumina calcined crystalline (gamma structure), or 2% crystalline (cubic) and alumina; silicon (silicic acid) is pyrogenic amorphous and monohydrate of aluminum oxide (A1OOH, boehmite) crystalline (gamma-structure) or silicon dioxide (silicic acid) precipitated amorphous and titanium dioxide on precipitated crystalline (modified anatas), 50–84 wt.% dispersed silicon dioxide (silicic acid) is amorphous with a particle size of 5–40 µm and t6–50 wt.% highly dispersed hydrate of aluminum oxide (aluminum hydroxide) precipitated crystalline ( gamma structure) with a particle size of 0.1-1 μm, or 5084 wt.% highly dispersed silicon dioxide (silicic acid), amorphous pyrogenic with a particle size of 0.008-0.016 microns and 16-50 wt.% highly dispersed alumina, pyrogenic crystalline (partially delta structures, mainly gamma structures) with a particle size of 0.005-0.04 m m, or 30-70 wt.% highly dispersed silicon dioxide (silicic acid) precipitated amorphous with a particle size of 5-40 microns and 30-70 wt.% highly dispersed silicon dioxide (silicic acid) pyrogenic amorphous with a particle size of 0.008-0.0166 microns, or 30-70 masl of highly dispersed titanium dioxide pyrogenic crystalline (partially modified rutile, mainly anatas modification) with a particle size of 0.015-0.04 microns and 30 to 70 wt.% Highly dispersed silica (silicic acid) pyrogenic amorphous with a particle size of 0.008-0.096 microns, or 30-80 wt% high dispersion Noah silicon dioxide (silicic acid) pyrogenic amorphous with a particle size of 0.0080, 016 microns and 20-70 wt.% highly dispersed aluminum oxide hydrate (aluminum hydroxide) precipitated crystalline (gamma-structure) with a particle size of 0.1-1 microns, or 70 wt.% highly dispersed silicon dioxide (silicic acid) precipitated amorphous with a particle size of 5-40 microns and 30 wt.% highly dispersed magnesia calcined crystalline (cubic) with a particle size of 0.5-2 microns, or 80. wt.% highly dispersed silica (silicic acid) precipitated amorphs particles with a particle size of 5–40 µm and 20% by weight of dispersed calcium oxide calcined crystalline (cubic) „with a particle size of 0.2–1 µm, or 30 wt.% highly dispersed magnesia calcined crystalline (cubic)) with a particle size of 0.5-2 microns and 70 wt.% Highly dispersed alumina calcined crystalline (gamma structure) with a particle size of 1-6 microns, or 50-84 wt.% Highly dispersed silica (silicic acid) precipitated amorphous with a particle size of 5- 40 μm and 16-50 wt.% Highly dispersed oxide monohydrate, alk Ini (А100Н, boehmite) crystalline (gamma struktT5fa) with a particle size of 0.060, 2 microns, or 30-80 wt.% highly disintegrant silicon dioxide (silicic acid) pyrogenic amorphous with a particle size of 0, 016 microns and 20-70 % By weight of high dispersed alumina monohydrate (A100H, boehmite) crystalline (gamma-structure) with a particle size of 0.06-0.2 μm, or 80 wt.% Highly dispersed silica (silicic acid) precipitated amorphous with a particle size of 50 -40 µm and 20 wt.% Highly dispersed titanium dioxide precipitated crystalline (anatas modification) with a size ohm 0.1-0.6 µm particles after mixing is introduced at room temperature and a pressure of 1000 mbar in a three-tenfold by weight amount of dispersant. By mixing the resulting mixture at a speed of 6003000 rpm, followed by stirring the mixture at the same rate at a room temperature or a temperature corresponding to the boiling point of the dispersant and a pressure of 20-1000 mbar and complete removal of the dispersant by evaporation; liquid air is used as the dispersant, as well as a mixture of 24 ob.h. ethanol and 1 ob.h. water.

    Products mixed in a ratio of 70% by weight of silica and 30% by weight of alumina hydrate are added to five times the weight of the mixture of 24 parts by volume. ethanol and 1 ob.h. water, with vigorous stirring at a speed of 800 rpm for 3 hours. With further stirring, the suspension is heated, at the same time a reduced pressure is created using vacuum, while the dried air is constantly sucked through the mixture and the IMM continues to operate until the liquid is completely removed.
    The creeping powder is conditioned at 20 ° C and relative air humidity of 60%. At the same time, it precipitates in a loose, very fine form. The bulk density of the obtained product is 62 g / l, the specific surface area is 163, the absorption of water vapor is 7.5 wt.%.

    In tab. 1 shows the results of pyrolysis of smoking tobacco with inorganic additives.
    In tab. 2 shows the results of smoking a filter cigarette with inorganic additives in an amount of 3 wt.% In the filter.
    Example 2. For the preparation of the proposed additive, the following are used: a) silica as in Example 1; b) silicon dioxide (krenic acid) pyrogenic amorphous, the average size of individual particles is 12 nm.
    The products are mixed in a ratio of 30% by weight of precipitated silica and 70% by weight of pyrogenic silica and added to 3 times the weight of liquefied air with vigorous stirring.
    The subsequent stages of the method correspond to Example 1, and the use of liquid air makes it possible to refuse pumping out and losing air.
    Get the powder, which has properties similar to the liquid, as obtained according to example 1.
    The substance obtained from precipitated silica and pyrogenic silica is an excellent additive (see Table 5).
    Other liquids can be used to prepare the additive, as long as they do not have the properties of solvents for the products used.
    The initial products dp for preparing the additive have the following sizes of individual particles:
    Titanium dioxide
    30 pyrogenic, nm Titanium dioxide
    20 pyrogen, nm. Magnesium oxide to al tsinovarnana, mkm
    Calcium oxide to alcanium n500 on, nm Aluminum oxide calcined, mkm3
    Since the initial products used are metallic compounds, they all have a polar nature, so that a variety of interactions between their surfaces are possible, namely: the complexation of various metal ions, the formation of hydrogen bridges, partial salt formation, ion exchange, electrical electrostatic effects that can lead to particle repulsion. For example, after shaking in a glass vessel, pyrogenic silicic acid carries a negative charge on the surface, precipitated silicic acid is positive, pyrogenic titanium dioxide is positive, crystalline aluminum hydroxide is positive, and aluminum oxide obtained by calcining aluminum hydroxide is negative, pyrogenic oxide not charged and magnesia also carries no charge. The additive can be applied or powdered onto the surface of the base materials of which the smoking tobacco products and filter elements are made. In tab. Figure 3 shows the results of Smoking cigarettes (without filter) from natural tobacco with inorganic additives taken in an amount of 10% by weight. The natural tobacco mentioned in table. 1 and 3, is a mixture of light and dark tobacco varieties. Inorganic additives are homogeneously distributed on its surface. Cigarettes with a length of 70 mm are prepared without a filter from pretreated tobacco and selected to smoke by the same weight and flow resistance of gases. The table below. 1, the results of pyrolysis were obtained under certain conditions, namely, at an air flow rate of 17.5 ml / s. Cigarettes (Table 3) are smoked up to the remainder of a length of 8 mm with the help of a cigarette smoking machine that includes 30 cigarettes with electrostatic discharge of condensate from the smoke. From tab. 1 and 3, it follows that the reduction of harmful components in tobacco smoke does not depend on the high or low specific surface of the additives introduced, but is always associated with the participation of special substances, due to which the best results are achieved. This is important both for natural tobacco, which contains the added material on the surface, as well as for artificial tobacco, in which the additive is added to the mass, or its mixtures with natural tobacco (Table 1). In tab. 2-8 shows the results of comparative experiments on cigarettes with a filter containing various additives. For filter cigarettes, always the same cigarette extrusion is used, tobacco corresponds to a tobacco mixture of light and dark varieties of tobacco (Tables 1 and 3). Filters for cigarettes have a hydraulic resistance to the flow of gases of 80 mm of water. Art. and have a diameter of 7.9 mm and a depth of 20 mm. For them, a bundle of twisted yarns of cellulose 2,5-acetate is used with a titer of separate yarns of 2.1 denier and a Y-shaped cross section of the yarn. The length of cigarettes (Tables 2, 4-8) is 85 mm. Smoking of cigarettes (Tables 2, 4-7) is carried out up to a residue of 28/20 mm of filter length and 8 mm of tobacco residue (under the conditions specified in Table 3). The results table. 8 are obtained using a dp smoking machine that can hold only one cigarette, with condensation on the filter. The entire gaseous phase of tobacco smoke, to determine the proportion of tobacco smoke passing through the filter, is trapped in the collecting cylinder of the smoking machine, and then analyzed by chromatography. The column used for gas-chromatic separation of individual substances is 2 m long. All filters contain inorganic additives in an amount of 3% by weight, which are evenly distributed on the surface of the base materials, filters, i.e. cellulose acetate yarns. From tab. 2, 4-8, it can be seen that the decrease in the number of harmful components in tobacco smoke does not depend on the high or low specific surface of the additive used, but is associated with the introduction of the proposed additive. According to the table. 8, the proposed additive not only reduces the amount of condensate in the smoke, but also greatly reduces the amount of polar components of the organic gas phase of tobacco smoke, nalimer acetapedehyde, acetonitrile, and acrolein. Instead of alumina hydrate, alumina monohydrate (А100Н, crystalline boehmite (gamma structure) with an average size of individual particles 100 nm can be used without loss. The same is true when the calcium oxide described is replaced by precipitated crystalline titanium dioxide (anatase modification) with an average size of individual particles of 300 nm. Table 4-8 shows the results of smoking cigarettes with a filter with inorganic additives in an amount of 3 wt.% in the filter. The components of the proposed additive are as follows: a) a mixture of two silica (silicic acid) pyrogenic amorphous and aluminum oxide hydrate (alcmini hydroxide) precipitated crystalline (gamma structure) in the following ratio, wt.% .: Silica 25-85 Alumina hydrate 15-75 b) mixture of silica (silicic acid ) precipitated amorphous and hydrated alumina (aluminum hydroxide) precipitated crystalline (gamma structure) in the following ratio, wt.%: Silica 45-90 Alumina hydrate 10-55 c) mixture of silica (silicic acid) amorphous pyrogenic and aluminum oxide and pyrogenic crystal (a little delta, mainly gamma structure) in a general ratio, wt.%: silicon dioxide alumina g) a mixture of silica (silicic acid) precipitated amorphous and silica (pyrogenic silicic acid amorphous in the following relation , weight,%: Silicon dioxide precipitated pyrogenic silicon dioxide d). mixture of silicon dioxide (silicic acid) pyrogenic amorphous titanium dioxide and pyrogenic crystalline (partially rutile, mainly anatase modification) in the following Determination, wt.%: Silica 25-75 Titanium Dioxide 25-75 e) a mixture of silica (silicic acid) precipitated amorphous and magnesia calcined crystalline (cubic) in the following ratio, wt.%: Silica (MgO) g) mixture silica (silicic acid) precipitated amorphous and calcium oxide calcined crystalline (cubic) in the following ratio, wt.%: silicon dioxide calcium oxide g) a mixture of magnesia calcined crystalline (cubic) and alumina calcined crypt steel (gamma structure) in the following ratio, wt.%: Magnesium oxide 20-40 Ashomini oxide 60-80 After the action has become known on these metal oxides, hydrates of metal oxides and the proposed mixtures, it is clear that these mixtures are also combined with each other and / or with other components. By combining suitable highly dispersed metal oxides and / or their hydrates as additives to tobacco products and their filament elements, it is more convenient to manipulate, making it possible to evenly distribute them on or in the main materials of tobacco smoking products and fnlters. The use of the proposed additive ensures the reduction of harmful components of tobacco smoke.
