Problems solved by technology

However, none of the above methods and substances can selectively reduce phenolic compounds
[0004] At present, there are few relevant reports related to the reduction of phenol. Only CN 102266123 A reports a β-cyclodextrin composite particle and its application for selectively reducing phenolic compounds in smoke. The selectivity of phenol is reduced by more than 40%, but This method needs to make functional materials into binary composite filter rods, which will not only change the production and processing technology of the filter rods of most cigarette industrial enterprises at present, but also increase the cost of cigarettes significantly, making it difficult to apply in industry

Embodiment example 1

[0014] Implementation case 1 (reduce the release of phenol in the flue gas by increasing the suction resistance of the filter rod)

[0015] Select the same cigarette formula leaf group, fix other auxiliary material parameters unchanged, only change the suction resistance of the acetate fiber filter rod, the filter rod suction resistance range is gradually increased from 3600 Pa to 4800 Pa. Then the determination of phenol and tar in the flue gas was carried out, and the results are shown in Table 1. It can be seen from the results that: taking the filter rod suction resistance of 3600Pa as the control sample, with the increase of the filter rod suction resistance, the release amount of phenol in the flue gas selectively decreased, and the highest drop was 12.6%.

Embodiment example 2

[0018] Implementation case 2 (selectively reducing the release of phenol in the flue gas by increasing the length of the filter rod)

[0019] The same cigarette formula leaf group was selected, other auxiliary material parameters were fixed unchanged, only the length of the acetate fiber filter rod was changed, and the length of the filter rod was increased from 24 mm to 27 mm. Then the determination of phenol and tar in the flue gas was carried out, and the results are shown in Table 2. It can be seen from the results that: taking the filter rod length of 24 mm as the control sample, when the filter rod length increased from 24 mm to 27 mm, the selective release of phenol in the flue gas decreased by 16.7%.

Embodiment example 3

[0022] Implementation case 3 (selectively reducing the release of phenol in smoke by increasing the content of triacetin)

[0023] The same cigarette formula leaf group was selected, other auxiliary material parameters were fixed unchanged, only the application amount of triacetin in the acetate fiber filter rod was changed, and the application amount of triacetin was gradually increased from 3.06% to 10.35%. Then the determination of phenol and tar in the flue gas was carried out, and the results are shown in Table 3. It can be seen from the results that: taking 3.06% of triacetin as the control sample, with the increase of triacetin, the release of phenol in the flue gas selectively decreased, with a maximum decrease of 33.5%.

Abstract

The invention discloses a method for selectively reducing phenol in smoke, which is characterized by being realized through optimizing the parameter of a cigarette filter stick, wherein the parameter of the cigarette filter stick contains the suction resistance optimization range of the filter stick, which is 3600-4800Pa. The length optimization range of each filter stick is 24-27mm, and the plasticizer content optimization range of the filter stick is 3.06-10.35%. The release amount of the phenol in the smoke of a cigarette can be selectively reduced, harm to smokers is reduced, and meanwhile, the taste of the cigarette is not affected. The method provided by the invention is simple and convenient for process and application, easy to implement and remarkable in harm reducing effect; and the current cigarette processing technology is not changed.

Description

technical field [0001] The invention belongs to the field of cigarette harm reduction, in particular to a method for optimizing parameters of cigarette filter rods for selectively reducing phenol in smoke. Background technique [0002] Phenolic compounds are a common class of compounds in nature, which are present in water, fuel, automobile exhaust, air, alcohol and cigarette smoke. There are more than 50 kinds of phenolic substances in cigarette smoke that have been reported, among which the most important phenolic compounds include 7 kinds of phenol, catechol, resorcinol, hydroquinone, o,m,p-cresol, etc. Element. Phenolic compounds can directly enter the blood circulation through contact with the skin and mucous membranes, resulting in protein denaturation, cell destruction and loss of vitality. And alkylphenols have endocrine disrupting activity, which affects the reproductive development of mammals and aquatic organisms, and are called phenolic environmental estrogens....
