The polymerisation degree of the sodium alginate alginic acid varies within the 500-900 range.EFFECT: fabrication of low flame propagation cigarette paper due to reduction of the cigarette carbon monoxide/resin ratio (C/T).5 cl, 1 dwg, 2 tbl

Reconstituted leaf tobacco and its production method (versions) // 2356458
FIELD: tobacco products.SUBSTANCE: methods proposed refer to reconstituted leaf tobacco production, as well as to production of modified reconstituted leaf tobacco. The methods are designed for cigarette manufacturing. One of the version refers to method of reconstituted leaf tobacco with binder production. The method implies production of suspension from tobacco and binder in given correlation. Preliminarily produced leaf of reconstituted tobacco, containing given quantity of wood paste, is enveloped with the suspension obtained. The suspension is complemented with a flavouring agent. The reconstituted leaf tobacco is supplemented with wetting reagent. A leaf of reconstituted tobacco is sliced into stripes. Several such stripes are placed into cigarette so that the stripes are adjacent to tobacco core. The other reconstituted leaf tobacco production version implies manufacturing of suspension from binder, wetting reagent, tobacco and flavouring agent, following defined proportions. The suspension is produced by sequential dispersion of tobacco, binder, wetting reagent and flavouring agent in water solvent. Then leaf production technological procedure is as described above. It also refers to cigarette, containing tobacco core, which is wrapped into outer envelopment, as well as to incomplete inner envelopment, presented by one or several stripes, made from reconstituted tobacco leaf. The inner envelopment is placed along the tobacco core, between the latter and outer envelopment. It also refers to reconstituted leaf tobacco, containing wood paste, binder and tobacco in defined proportion. The method of modified reconstituted leaf tobacco production includes the following operations. First, tobacco particle suspension is prepared in water solvent. The suspension obtained is then subjected to extraction processing at temperature of approximately 160°F for a period of approximately 30 minutes. Then the suspension is divided into extract with components, soluble in water, and solid fraction, which is mixed with wood paste and formed into leaf of reconstituted tobacco, using Fourdrinier machine. The extract is centrifugated, concentrated, supplemented with first binder and wetting reagent, applied to leaf of reconstituted tobacco and dried. Afterwards, the leaf is processed as described above.EFFECT: decrease of ignitability for smoking products with one-layer envelopment.50 cl, 8 dwg, 3 tbl, 3 ex

Reconstituted tobacco leaves and smokables made thereof // 2346629
FIELD: smokables.SUBSTANCE: strips of the inner wrap are coaxial to tobacco rod between that and internal surface of outer wrap of a cigarette. Tobacco mixture contains Burley tobacco and tobacco second type, e.g. flue-cured tobacco, Oriental tobacco, Maryland tobacco, rare tobacco, exotic tobacco or mixed.EFFECT: smoke aroma is closer to Burley tobacco smoke aroma without higher content of harmful components in smoke.63 cl, 11 dwg, 7 tbl, 4 ex

Tobacco articles with reduced burning capacity // 2313264
FIELD: tobacco articles and wrap for tobacco articles.SUBSTANCE: paper wrap is treated with film forming composition forming individual treated portions on wrap. Individual treated portions have permeability within predetermined range sufficient for reducing burning capacity of tobacco article manufactured with the use of wrap. Film forming composition contains film forming material having relatively low viscosity. Thanks to this property, film forming material may have relatively high content of solid substances and yet be fit for applying onto wrap by means of standard printing methods.EFFECT: increased efficiency in producing of tobacco articles capable of self-extinguishing upon falling onto inflammable materials.38 cl, 3 dwg
ethod of production of the microporous materials with the coating made out of the rare-earth metal oxide // 2306177
FIELD: chemical industry; oil-refining industry; other industries; methods of production of the catalytic microporous fine-dispersed materials.SUBSTANCE: the invention is pertaining to the method of production of the catalytic microporous fine-dispersed material, which is used in such processes, as purification of the oil fractions, purification of the sewage disposal, the catalytic conversion of the exhaust gases exiting from the combustion engines. The method allows to produce the catalytic microporous fine-dispersed material with the coating of the rare-earth metal oxide, in which the quantity of the metal oxide deposited on it is high without the risk for efficiency of the material. At that the rare-metal oxide is deposited on the outer surfaces of the indicated material and may be within the interval of 20-70 mass % with respect to with respect to the total equivalent content of the rare-earth metal oxide and the microporous fine-dispersed material. The method provides for the combination of the quantity of the colloid dispersion of the hydrate of the rare-earth metal oxide with the compatible microporous fine-dispersed material with formation of the suspension and the thermal treatment of the indicated suspension for the rare-earth metal oxide fixation on the outer surfaces of the indicated material. At that the indicated microporous fine-dispersed material has the average size of the pores less than 20 Å, and the indicated colloid dispersion has the particle size of the particles of not less than 20 Å. The invention also presents the catalytic free-loose fine-dispersed material with the rare-earth metal oxide coating containing the ceolite fine-dispersed material, the rare-earth metal oxide. At that the indicated ceolite fine-dispersed material has the average size of the pores less than the size of the particles of the indicated rare-earth metal oxide, and more than 20 mass % of the indicated rare-earth metal oxide is on the outer surfaces the indicated ceolite fine-dispersed material with respect to the total equivalent content of the rare-earth metal oxide and the ceolite. The ceolite free-loose fine-dispersed material having the high contents of the rare-earth metal oxide has the tendency to be the very stable material.EFFECT: the invention ensures production of the catalytic microporous fine-dispersed material with the coating of the rare-earth metal oxide without the risk for efficiency of the material and the ceolite free-loose fine-dispersed material having the high contents of the rare-earth metal oxide has the tendency to be the very stable material.31 cl, 11 ex, 3 tbl

Cigarette with low-level side-stream smoke, having ignitable paper with modified ash characteristics // 2305480
