    摘要： A unitary pack of smoking tobacco products is provided in which a flavorant is incorporated in some of the smoking tobacco products in the form of a polymeric alcohol flavorant-release composition which has the general formula: ##STR1## wherein R is selected from aliphatic, alicyclic, heterocyclic and aromatic hydrocarbon radicals; R.sup.1 and R.sup.2 are selected from hydrogen and aliphatic, alicyclic, heterocyclic and aromatic hydrocarbon radicals; and n is an integer. These polymers release a flavorant when heated. Such polymers include polymers formed from .alpha.-substituted vinyl menthyl carbonate esters, such as poly(.alpha.-methylvinyl .alpha.-menthyl carbonate) and poly(.alpha.-styryl .alpha.-menthyl carbonate), which release menthol when heated. Smoking tobacco products which are made with tobacco which has been treated with a particular alcohol flavorant-release composition have been found to show no significant loss in delivery of flavor. Other smoking tobacco products which are packaged therewith do not acquire the flavor of the flavorant which is contained in the alcohol flavorant-release composition, despite the absence of internal vapor barriers between the different flavored tobacco products.

    摘要翻译： 提供了一整套烟草制品，其中一些吸烟烟草制品中的风味剂以聚合醇醇调味剂释放组合物的形式并入，其具有以下通式：其中R选自脂族，脂环族 ，杂环和芳族烃基; R1和R2选自氢和脂族，脂环族，杂环和芳族烃基; 并且n是整数。 这些聚合物在加热时释放食用香料。 这样的聚合物包括由α-取代的乙烯基薄荷酯碳酸酯形成的聚合物，例如聚（α-甲基乙烯基α-碳酸酯）和聚（α-苯乙烯基α-碳酸亚乙酯）），其在加热时释放薄荷醇。 已经发现用特定的酒精调味剂释放组合物处理的用烟草制成的吸烟烟草制品在风味递送中没有显着的损失。 尽管在不同调味烟草制品之间没有内部蒸汽屏障，但与其一起包装的其它吸烟烟草制品也不会获得酒精调味剂释放组合物中所含的风味剂的风味。

    摘要： A process is provided for the improved removal of nicotine from tobacco. An essentially nicotine-free solvent in the supercritical or liquid state is fed into a first end of an extraction flow system containing tobacco and a nicotine-rich solvent is discharged from a second end of the extraction flow system. Periodically a portion of extracted tobacco is discharged from the first end of the extraction system while simultaneously a portion of an unextracted tobacco is charged to the second end of the extraction system. Nicotine is then entrapped in an entrapment material or otherwise removed from the solvent and solvent is recycled through the extraction flow system. Various materials are provided as entrapment materials. Among the entrapment materials provided are aqueous solutions containing absorbent selected from various acids and salts. Among the acids and salts provided as entrapment materials are sulfuric acid, phosphoric acid, nitric acid, tartaric acid, citric acid, malic acid, lactic acid, malonic acid, succinic acid, acetic acid, glutamic acid and monopotassium citrate.

    摘要： A method of forming a filter for a smoking article which includes exposing cellulose acetate fibers to an electron beam process, wherein electron beam process deacetylates the cellulose acetate fibers to render the cellulose acetate fibers water-permeable; and forming a cellulose acetate rod from a tow of the cellulose acetate fibers. Filter plugs of the cellulose acetate fibers are water-permeable and allow discarded filtered smoking articles to rapidly degrade and expose the components to the environment.
