Despite the widespread use of filters that remove tar and nicotine from cigarettes, the current situation is that they are not able to remove the harmful effects of cigarettes. In other words, although particulate matter such as tar and nicotine is a type of harmful substance, existing filters cannot remove other harmful substances present in cigarette smoke. This is because it is not possible.

oyment health Perspective
es, 1984.1 ~ 36) *Tobacco radicals, which are the residual substances, are present both in the cigarette smoke directly inhaled by smokers, that is, mainstream smoke, and in the rising smoke of cigarettes, that is, secondary smoke. It is also present in smoke. However, at present, there is no known filter that removes such radicals from cigarette smoke.

めて異なる。Radical is a general term for anything that has an unpaired electron. Therefore, different radicals are usually derived from different compounds, and the properties and reactivity of those radicals also naturally vary.For example, a methyl radical derived from a compound having a methyl group and a triphenylmethyl group react with each other. Their gender is extremely different.

ルについてのこれまでの常識から考えると驚くべきこと
である。For some radicals, scavengers are known as necessary. For example, it is a polymerization inhibitor for preventing radical polymerization reactions. However, this is only because the effect of inhibiting polymerization under specific conditions is known for specific radicals. The radicals present in cigarette smoke remain stable despite their high reactivity. This fact is surprising considering the conventional wisdom about radicals.
本発明の課題は、煙草の煙に存在するラジカルを喫煙す

As a result, it was discovered that a filter using the radical scavenger described later has a great removal effect even under smoking conditions, and the present invention was completed.

Examples include nitro compounds such as hydrazyl, and sulfur-containing compounds such as dimethyl carbamate.
煙草の燃焼ガス用フィルターとしては、代表的には直接

としては、ポリオキシ化合物、キノン類が好ましい。On the other hand, since the radical scavengers used in rational air purification filters are not of a nature that can be taken directly into the human body, their own safety is not as strict as that of the radical scavengers used in cigarette filters. However, since it is necessary to capture low concentration radicals diluted with air, it is necessary to use a highly reactive radical scavenger. Therefore, polyoxy compounds and quinones are preferred as radical scavengers used in rational air purification filters.

あればその含を方法は何等制限されない。If the radical scavenger is a solid, for example vitamin C, vitamin C is pre-supported on the activated carbon by dissolving the vitamin C in water, adding activated carbon, etc., which is known as a filler for filters, and drying under reduced pressure. do. Examples include a method of filling activated carbon or the like between filters, or a method of dissolving vitamin C in water or the like and impregnating filter fibers such as cellulose acetate fibers. Alternatively, a method may be mentioned in which filter fibers impregnated with vitamin C are freeze-dried, supported on the filter fibers, and used as is. Further, in the case where the radical scavenger is a liquid, for example, vitamin E, a method of directly impregnating the filter fiber with the radical scavenger may be mentioned. but,
There are no restrictions on the method of impregnating the filter as long as the effect of the present invention can be obtained by impregnating the radical scavenger with a method other than these methods.
また、本発明のフィルターに含有するラジカル捕捉剤は
、通常は細かく分散させたもの程ラジカルの除去効果が
良好であり好ましい。Further, the finer the radical scavenger contained in the filter of the present invention is, the more finely dispersed it is, the better the radical removal effect is, and therefore it is preferable.
したがって、ラジカル捕捉剤をフィルターに含有させる
方法としては、ラジカル捕捉剤を活性炭に担持して分散
させ、その活性炭をフィルター間に充填する方法が最も
好ましい。Therefore, the most preferable method for incorporating the radical scavenger into the filter is a method in which the radical scavenger is supported on activated carbon and dispersed, and the activated carbon is filled between the filters.
また、本発明のフィルターに含有させるラジカル捕捉剤
の量は、多い程、煙草のラジカル捕捉効果は大きいが、
多すぎるとフィルターの圧頃失が大きくなる。したがっ
て、フィルター付き煙草のフィルターに使用する場合に

。Furthermore, the greater the amount of radical scavenger contained in the filter of the present invention, the greater the effect of scavenging cigarette radicals.
If it is too large, the pressure loss of the filter will increase. Therefore, when used in the filter of a filter-equipped cigarette, an amount of 50 mg or less is sufficient for one cigarette.

以下、実施例により本発明のフィルターを更に詳細に説
明する。Below, the filter of the present invention will be explained in more detail with reference to Examples.
実施例１
５００＋＋ｇのベンゾキノンをガラスウールとともに充
填した長さ５ｃｍガラス管に市販の煙草（マイルドセブ
ン）を取りつけ、空気中で燃焼させた。この煙草の煙を
ガラス管からアスピレータ−で吸引し、スピントラップ
剤を調製した吸収液に直接、煙草が燃え尽きる迄導入し
た。Example 1 A commercially available cigarette (Mild Seven) was attached to a 5 cm long glass tube filled with 500++ g of benzoquinone together with glass wool and burned in air. The cigarette smoke was sucked through a glass tube with an aspirator and introduced directly into the absorption liquid prepared with the spin trap agent until the cigarette was burned out.
このスピン付加物をＥＳＲで観察し、ベンゾキノンを用
いていない場合と比較した結果、ベンゾキノンを用いた
場合のラジカル除去率は１１％であっ実施例 ２〜１２
実施例１と同様の方法で第１表のようにラジカル捕捉剤
およびその使用量を変化させてラジカル除去試験を実施
した。その結果を実施例１とともに第１表に示す。This spin adduct was observed by ESR and compared with the case where benzoquinone was not used. As a result, the radical removal rate when benzoquinone was used was 11%. A radical removal test was conducted by changing the radical scavenger and its usage amount as shown in the table. The results are shown in Table 1 together with Example 1.
