Problems solved by technology

[0005] The above technologies can reduce tar and other harmful substances at the same time through the blocking and adsorption of solid substances, but the effect is not as obvious as reported when applied to medium and low tar cigarettes, and cannot meet the requirement of highly selective reduction of single harmful components in cigarette smoke

Embodiment 1

[0025] Add N-methylimidazole, n-chlorobutane and toluene into the three-necked flask in sequence, and heat and stir for reaction. After the reaction is finished, it is washed and recrystallized, and the obtained product is dried in a vacuum oven. This gives 1-butyl-3-methylimidazole chloride (BMIC). AlCl 3 Slowly add to BMIC in proportion, and stir in a dry box for 20 hours. To prevent AlCl 3 Decomposition, the reaction is carried out in an inert atmosphere. 1-butyl 3-methylimidazolium chloroaluminate ([BMIM]-AlCl 4 ), according to 10% load, it was slowly added dropwise to the pre-dried and calcined SiO 2 until the surface of the carrier turns from dry to wet, stirring overnight. The excess ionic liquid was extracted with dichloromethane in a Soxhlet extractor, dried under vacuum at room temperature for 16 hours after extraction, and stored in an inert atmosphere. Get [BMIM]-AlCl 4 / SiO 2 Add it to the cellulose acetate filter to make a binary composite tip stick, the...

Embodiment 2

[0027] Take 10ml of ethyl orthosilicate, heat it to 70°C with an oil bath while stirring, then take 1ml of ionic liquid DMImBF4 (1-decyl-3-methylimidazolium fluoroborate), add 8ml of absolute ethanol, and mix well Then transfer it to ethyl orthosilicate, then add 3ml of concentrated hydrochloric acid and 3.5ml of water, after 12 hours to form a gel, continue aging for 24 hours, and finally dry it in vacuum at room temperature for 24 hours to obtain the catalyst DMImBF 4 / SiO 2 -gel about 4.8g. Then add it to the cellulose acetate filter to make a binary composite tip stick, the addition amount is 10mg, and the composite filter tip is rolled into a cigarette. The composite tip stick has tar, CO, phenol, catechol, resorcin The removal rates of phenol, hydroquinone, p-cresol and (o+m)-cresol were 0.0%, 0.0%, 16.64%, 20.71%, 10.23%, 10.10%, 9.83%, 5.98%, respectively.

Embodiment 3

[0029] First activate MCM-41, then add non-aqueous toluene, stir and disperse, add 1-ethyl (triethoxysilyl)-3-methylimidazole iodide salt, stir at 90°C for 10h, toluene and The generated ethanol is removed by distillation, and excess 1-ethyl (triethoxysilyl)-3-methylimidazole can be removed by vacuum distillation after adding dichloromethane. Add FeCl 3Stir for 6 hours, the excess halide can be removed by Soxhlet extraction method, wherein the load of ionic liquid is 10%, and then added to the cellulose acetate filter to make a binary composite nozzle stick, the addition amount is 40mg, and the composite filter Mouth rolled into cigarettes, the removal rates of tar, CO, phenol, catechol, resorcinol, hydroquinone, p-cresol, and (o+m)-cresol were respectively 0.0%, 0.0%, 32.58%, 19.46%, 22.13%, 15.98%, 8.91%, 10.25%.

Abstract

This invention provides an additive which can reduce the phenols content of cigarette fumes selectively; the additive is an inorganic carrier or acetate fiber which can load ionic liquid, is added into the filter of acetate fiber so as to produce a binary complex filter, thus being capable of reducing the phenols content of cigarette fumes high selectively and having no effect on the cigarette mouth-feel in the process of reducing the damage to smokers. The additive preparation technology of the invention is simple, and the additivity is convenient and the additive can meet the requirement of industrial production.

Description

technical field [0001] The invention belongs to the technical field of cigarette preparation, and in particular relates to an additive for reducing the content of phenolic substances in cigarette smoke, a preparation method and an application thereof. Background technique [0002] Affected by the World Health Organization and the anti-smoking campaign, the contradiction between smoking and health has become increasingly prominent. Cigarette combustion is a complex reaction. As one of the main components in smoke, there are 40 kinds of phenolic compounds, the most important of which are phenol and catechol. The phenolic compounds in cigarette smoke are mainly derived from the cracking of polyphenolic compounds (chlorogenic acid and rutin) in tobacco leaves. There is evidence that the presence of phenolic compounds can significantly increase the carcinogenic activity of polycyclic aromatic hydrocarbons, especially phenol, O-, m-, and hydroquinones, and o-, m-, and p-cresols a...
