- Figure 1 shows the SEM image of a fibrous SBA-15 (A) and a spherical SBA-15 (B).
- Figure 2 shows N 2 adsorption isotherms obtained for SBA-15 materials synthesized in different ways.
- the SBA-15 was synthesized following the following procedure: initially a solution of pluronic P 123 in acidic medium was prepared to which an amount of tetraethylorthosilicate (TEOS) was added. The resulting solution was aged under stirring at 38 ° C for 20 h. It was subsequently transferred to an autoclave with a Teflon jacket and kept at 100 ° C for 24 hours. The resulting suspension was washed with water, dried overnight at 100 ° C and finally calcined at 550 ° C for 5h (F. Zhang, Y. Yan, H. Yang, Y. Meng, C. Yu, B Tu, D. Zhao, Journal of Physical Chemistry B.109 (18), (2005), 8723).
- TEOS tetraethylorthosilicate
- the SBA-15 eS was obtained under the following conditions. An amount of Pluronic P 123 was dissolved in HCI. A second suspension was prepared with CTABr and water, and added to the first. Subsequently a small amount of ethanol was added, followed by an addition of TEOS. The resulting solution was aged at 35 ° C for 45 min. Subsequently, it was transferred to an autoclave with a Teflon jacket at 75 ° C for a few hours and finally treated at 105 ° C. The resulting suspension was washed with water, dried overnight at 100 ° C and finally calcined at 550 ° C, (A. Katiyar, S. Yadav, PG. Smirniotis, NG. Pinto, Journal of Chromatography A, 1122 (1-2), (2006), 13.).
- SBA-15 materials fi xed U was obtained in similar conditions SBA-15, but in the final stage a flask containing the suspension connected obtained a reflux condenser at 100 ° C was used. The resulting solid was washed with water, dried overnight at 100 ° C and finally calcined at 550 ° C.
- SBA-15 material at 125 ° C was prepared in the same way as SBA-15 but by modifying the temperature at which it is maintained during the final process temperature, 125 ° C instead of 100 ° C.
- the AISBA-15 material was prepared using a gel of molar composition: 1 TEOS: 0.02 Al 2 0 3 : 0.016 P123: 0.46 HCI: 190 H 2 0, according to the procedure described by Vinu A., Hartmann M., Devassy BM, Halligudi SB, Bohlmann W., Applied Catalysis A: General, 281, (2005), 207.
- the Na-AISBA-15 material was prepared by ion exchange from the AISBA-15 material, where 1 gram of material is stirred 24 h with a 1 M solution of NaCI. The resulting material is filtered, washed with water and dried in an oven at 100 ° C.
- the FeNa-AISBA-15 material was prepared by ion exchange of the Na-AISBA-15 material, where in 1 liter of distilled water with 1.26g of Fe (N0 3 ) 9H 2 0 and 4.5g of Na-AISBA- is added fifteen. The resulting solution is stirred for 24 hours, and then filtered, washed with water and dried in an oven at 100 ° C.
- Table 1 shows the chemical and structural characteristics of some of the additives studied in this application, as representative examples of this type of materials, which correspond to samples of SBA-15 prepared under different synthesis conditions or subjected to post-synthesis modifications.
- Figure 2 shows the corresponding isotherms of N 2 to 77 K corresponding.
- the cigarettes were conditioned at room temperature and 60% relative humidity, keeping them in a desiccator provided with a saturated solution of sodium nitrite, at least for 48 hours before being smoked.
- smoke including CO, C0 2 and other non-condensable products
- a trap fiberglass filter located before the gas collection bag.
- the non-condensable products were collected in a Tediar gas bag, which was reserved for further analysis by gas chromatography (GC) and the condensable products were collected in the cigarette filter and in the subsequent trap, where the condensable products were retained They were directly inhaled by smokers.
- GC gas chromatography
- the condensable products retained in the post filter trap were extracted with 2-propanol, ensuring that all the compounds retained in the trap are recovered.
- the extract is then dried with sodium sulfate and reserved for further GC analysis.
- the determination of the CO and C0 2 content in the non-condensable fraction was carried out by GC, using a thermal conductivity detector (GC-TCD) and a concentric CTRI column, which was also used for the analysis of 0, 2 2 and CH 4 , in a SHIMADZU GC-14A device, using a calibration using external standards. Quantification was performed by calculating the response factor (grams of compound / peak area) of these compounds by injecting different volumes (between 0.5 and 2.5 mL) of the corresponding standard (carbon monoxide, carbon dioxide, hydrogen, methane and oxygen).
- Carrier gas He Injector temperature: 28 ° C
- GC-FID flame ionization detector
- Injector temperature 150 ° C
- Carrier gas Helium
- the condensable compounds (extracted with 2-propanol from cigarette filters and smoke traps) were analyzed by GC with mass spectrometry detector (GC-MS), using an HP-5MS column and the following conditions :
- Carrier gas Helium
- nicotine standards of different concentrations were prepared. They were injected into the equipment and from the slope of the line obtained from the graphic representation of the amount of compound injected against the peak area, the corresponding response factor value was obtained. The response factor obtained for nicotine was used for the rest of the compounds analyzed, since nicotine was the majority compound. Quantification was carried out analogously for gases, where an average response factor was used in cases where the corresponding response factor was not available.
- cigarettes were prepared in which the tobacco fibers were mixed by hand with the catalyst, with the help of a few drops of ethanol. This operation was performed on a sieve that allowed to separate the catalyst that was not adhered to the tobacco, so that a percentage of catalyst was obtained in the nominal mixtures, which corresponded to the amount of initially heavy catalyst, and a real one, which was the retained by the sample.
- Other agents that are alternative to ethanol that can help in the tobacco-catalyzed mixing process are water, glycerin and other similar compounds, usually present in tobacco preparations and that evaporate with relative ease. However, mixtures can also be carried out satisfactorily without using any of these substances.
- Cigarettes were prepared using the procedure described in "cigarette preparation conditions" and using the additives indicated below. Table 2 shows the mixtures carried out in the different tests performed. Mixes
- Tables 3, 4, 5 and 6 present the results obtained when smoking cigarettes using the conditions of preparation of cigarettes, smoking conditions and analysis of the products generated and the examples corresponding to different tobacco-additive mixtures. The values obtained for:
- TPM Total particulate matter
- m 0 is the mass of the post filter trap, in mg, before smoking
- ⁇ is the mass of the post-filter trap, in mg, after smoking a q number of cigarettes.
- Tables 3 to 6 show that, in general, the proposed additives, mixed with tobacco in the proportions described, provided a significant reduction in the amount of most of the toxic compounds that appear in tobacco smoke. This reduction in turn meant a decrease in the potential negative effects caused by tobacco smoke in smokers and passive smokers, without causing appreciable changes in organoleptic properties and taste and consistency of tobacco, and without apparent generation of other undesirable compounds.
- the toxic compounds were reduced, but in general, the total amount of gases and liquids formed by smoking the cigarette (total particulate matter, TPM, plus the liquids retained in the filter) while The solid residue increased along with the ashes. At the end of the process of smoking the cigarette, the additives were retained in the ashes or in the tobacco that has not been smoked.
- Table 3 shows the yields obtained for CO and C0 2 to smoking cigarettes prepared with the described mixtures are presented.
- SBA-15 when used in nominal proportions of 6 and 8%.
- the materials SBA-15 eS Férica, SBA-15 eS Férica and SBA-15 at 125 ° C also provide significant reductions for CO. This is especially interesting since CO is one of the substances regulated by the regulations applicable to commercial cigarettes.
- the other additives also provide a reduction in CO, although minor, with the sole exception of FeNa-SBA-15, which causes a slight increase.
- Table 5 shows, as an example, the results obtained for the production of some toxic and carcinogenic compounds that appear in tobacco smoke.
- all additives provided a reduction in the formation of propionaldehyde with respect to the reference cigarette.
- Toluene interesting reductions were also observed, with the sole exception of the NaFe-SBA-15 material, which caused a slight increase.
- Similar considerations can be made for benzene and acetaldehyde: reductions are observed for benzene in all cases, except for SBA-15 eS and ferric SBA-15 eS at 125 ° C, which cause a Black increase.
- the only additive that causes reductions with respect to the reference cigarette is SBA-15.
- Table 6 shows the results obtained for other compounds present in tobacco smoke in the case of reference tobacco and with 4 of the additives studied. Again, the excellent behavior shown by the SBA-15 sample can be verified, with reductions ranging between 95% for phenol and 39% for nicotine.
- the SBA-15 eS ferric material also caused reductions for the 7 compounds studied, while FeNa-SBA-15 caused an increase in all of them, except benzaldehyde.
- All of the described mixtures can also be prepared by using fast mixers, fluidized or entrained beds and any other type of equipment that favors the mixing between tobacco fiber and the additive. Sieves can also be used to separate and recirculate the additive that had not been fixed on the tobacco fibers.
- a dispenser can be used that provides the appropriate amount of catalyst for the preparation of blond tobacco , black, leaf bite, rolling tobacco, pipe tobacco and any other product that can be smoked.
- This dispenser can consist of a blister pack, where each cavity contains the selected quantity (between 5 and 70 mg, so that it is obtained between 0.5 and 7% with respect to tobacco, which will usually be consumed in portions of about 1 g of tobacco ), individual capsules containing said amounts, a container that includes a calibrated or graduated teaspoon or any other calibrated dispenser.
- the ready-to-smoke product MYO, RYO, pipe or other forms
- the content of the calibrated dispenser is poured onto the tobacco fiber and carefully mixed by hand. This procedure guarantees excellent results, as good as those presented in Tables 3 to 6.
- Cigarettes were prepared using the procedure described in "cigarette preparation conditions" and using the nominal concentrations (weight percentage) of 4, 6 and 8%.
- Results obtained corresponding to tobacco-additive mixtures with different concentration of additive were also studied.
- concentration of the additive in the additive-tobacco mixtures was also studied.
- mixtures with a nominal percentage of catalyst between 4 and 8% were prepared, using the procedure described above.
- tables 7 and 8 show the results obtained when SBA-15 is used as an additive. As can be seen, the best results were achieved when the maximum concentration of additive was used, although in the mixtures with intermediate concentrations excellent results were also obtained, which can be adjusted according to the reduction of the desired toxic compounds.
