Example Embodiment

[0024] Example 1:

[0025] Add N-methylimidazole, chloro-n-butane and toluene sequentially into a three-necked flask, and heat and stir for reaction. After the reaction is completed, washing and recrystallization are performed, and the resulting product is dried in a vacuum drying oven. This gives chloro 1-butyl-3-methylimidazole (BMIC). AlCl 3 Slowly add BMIC in proportion and stir for 20 hours in a dry box. To prevent AlCl 3 Decomposition, the reaction proceeds in an inert atmosphere. Synthesis of 1-butyl 3-methylimidazole chloroaluminate ([BMIM]-AlCl 4 ), add it slowly to the SiO which has been pre-dried and calcined at 500℃ for 3h according to the loading amount of 10% 2 On the carrier, stir overnight until the surface of the carrier turns from dry to wet. The excess ionic liquid was extracted with dichloromethane in a Soxhlet extractor. After extraction, it was dried under vacuum at room temperature for 16 hours and stored in an inert atmosphere. To get [BMIM]-AlCl 4 / SiO 2 A...

Example Embodiment

[0026] Example 2:

[0027] Take 10ml of ethyl orthosilicate, heat it to 70℃ in an oil bath while stirring, then take 1ml of ionic liquid DMImBF4 (1-decyl-3-methylimidazole fluoroborate), add 8ml of absolute ethanol, and mix well Then transfer to ethyl orthosilicate, then add 3ml of concentrated hydrochloric acid, 3.5ml of water, 12 hours to form a gel and continue to age for 24 hours, and finally vacuum drying at room temperature for 24 hours to prepare the catalyst DMImBF 4 / SiO 2 -gel is about 4.8g. Then add it to the cellulose acetate filter to make a binary composite tip. The addition amount is 10mg. The composite filter is rolled into a cigarette. The composite tip is tar, CO, phenol, catechol, and resorcinol. 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%, and 5.98%, respectively.

Example Embodiment

[0028] Example 3:

[0029] Activate MCM-41 first, then add toluene without water, after stirring and dispersing, add the iodide salt of 1-ethyl(triethoxysilyl)-3-methylimidazole, stir at 90℃ for 10h, toluene and The produced ethanol is removed by distillation. After adding dichloromethane, the excess 1-ethyl(triethoxysilyl)-3-methylimidazole can be removed by vacuum distillation. Join FeCl 3Stir for 6 hours. Excess halide can be removed by Soxhlet extraction method. The loading amount of ionic liquid is 10%, and then it is added to the cellulose acetate filter tip to make a binary composite tip rod. The addition amount is 40mg. The mouth is rolled into a cigarette, and the removal rates of the composite tip stick are tar, CO, phenol, catechol, resorcinol, hydroquinone, p-cresol, and (o+m)-cresol, respectively 0.0%, 0.0%, 32.58%, 19.46%, 22.13%, 15.98%, 8.91%, 10.5%.

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...
