Embodiment 1

[0025] Take a certain amount of p-[1-(4-hydroxyphenyl)-1-methylethyl] calix[8]arene, add it in the tip stick with 10mg / cigarette, and make the filter tip containing the additive of the present invention. Test cigarettes are compared with control cigarettes. Except that the control cigarettes did not contain additives, other materials such as auxiliary materials, size specifications, mouth sticks, etc. were exactly the same as the test cigarettes.

[0026] The test cigarettes and control cigarettes were smoked with an SM400 automatic smoking machine under standard smoking conditions, and smoke samples were collected according to the standards and general smoke detection methods in the tobacco industry, and the smoke-related harmful components were tested according to the requirements of different test items. analysis detection. The amount of tar is detected according to the national standard GB / T 19609-2004; polycyclic aromatic hydrocarbons are detected by gas chromatography-m...

Embodiment 2

[0034] Take a certain amount of p-[1-(4-hydroxyphenyl)-1-methylethyl] calix[8]arene, add it in the tip stick with 8mg / cigarette, and make the filter tip containing the additive of the present invention. Test cigarettes are compared with control cigarettes. Except that the control cigarettes did not contain additives, other materials such as auxiliary materials, size specifications, mouth sticks, etc. were exactly the same as the test cigarettes.

Embodiment 3

[0041]Take a certain amount of p-[1-(4-hydroxyphenyl)-1-methylethyl] calix[8]arene, add it in the tip stick with 12mg / cigarette, and make the filter tip containing the additive of the present invention. Test cigarettes are compared with control cigarettes. Except that the control cigarettes did not contain additives, other materials such as auxiliary materials, size specifications, mouth sticks, etc. were exactly the same as the test cigarettes. The evaluation method and technology of additives on the harm reduction effect of cigarette smoke are the same as in Example 1, and the harm reduction effect data is close to that of Embodiment 1.

Abstract

The invention discloses a calixarene additive capable of simultaneously and optionally reducing benzo (a) pyrene and phenol contents in cigarette smoke and an application method thereof. In the invention, deep-cavity P-(1-(4-hydroxyphenyl)-1-methylethyl) calyx (8) aromatic compound is selected as the additive material, and the compound is added in a common and conventional filter tip which bettercan be suitable for a compound filter, with the additive amount being arbitrarily adjusted according to the needs. By using the molecular recognition function and the cavity size select effect of thecalyx (8) aromatic compound, the additive can be optionally combined with the benzo (a) pyrene and phenol molecules in the cigarette smoke. When the additive is added into the filler with the amount of 10mg/per cigarette, 33.2 percent of benzo (a) pyrene content and 41.4 percent of phenol content in the cigarette smoke can be simultaneously reduced, and other chemical compositions in the smoke arebasically not influenced, thus achieving the goal of selective harm reduction.

Description

technical field [0001] The present invention relates to a method for selectively reducing the content of benzo[a]pyrene and phenol in cigarette smoke by using calixarene compounds, in particular using calix[8]arene compounds to selectively reduce benzo[a]pyrene in cigarette smoke and phenol content method techniques. Background technique [0002] The tar and harm reduction of cigarette products is an important issue related to the health of smokers and passive smokers, which has attracted great attention from the tobacco industry. Over the years, domestic and foreign tobacco research institutes and cigarette manufacturers have been devoting themselves to research on cigarette tar reduction and harm reduction, and have achieved a large number of research results. The harmful components in cigarette smoke have been relatively greatly reduced. However, the harm reduction methods used in the past are not very selective, which partially affects the original style and taste of ci...
