Embodiment 1

[0015] Sieve the porous hydroxyapatite to take 10g of 20-100mesh particles, add 100ml dimethyl sulfoxide, 20g trimethylammonium acetylhydrazide chloride and 3~5 drops of acetic acid to it, stir and react at 30°C for 24h, After the reaction, wash with water until neutral, soak in 1mol / L NaOH solution for 2h, wash with water until neutral, and then vacuum dry at 30-50°C for 10-30min to obtain quaternary amine alkalized porous material 1.

[0016] The porous material 1 is used as a composite filter additive material, the additive amount is 40 mg / cig, and the cigarette without any filter modified material is used as a control sample, and the cigarette smoking test is carried out on a smoking machine according to the standard smoking conditions, and according to The standard YCT253-2008 is used to detect the amount of hydrogen cyanide released. Three parallel samples were taken for each sample, and the results are shown in Table 1.

Embodiment 2

[0021] Sieve porous silica (commercially available) to take 10g of 20-100 mesh particles, add 180ml of methanol and 20g of (2-bromoethyl)trimethylammonium bromide, and stir at room temperature for 1h to make (2-bromoethyl) Base) trimethylammonium bromide was fully dissolved, then heated to 65°C, and reacted for 24h. After the reaction, wash with water until neutral, soak in 2mol / L NaOH solution for 1 h, wash with water until neutral, and then vacuum dry at 30-50° C. for 10-30 min to obtain quaternary amine alkalized porous material 2 .

[0022] The porous material 2 is used as a composite filter additive material, the additive amount is 20 mg / cig, and the cigarette without any filter modified material is used as a control sample, and the cigarette smoking test is carried out on a smoking machine according to the standard smoking conditions, and according to The standard YCT253-2008 is used to detect the amount of hydrogen cyanide released. Each sample has three parallel sampl...

Abstract

The invention relates to a filter additive material for selectively reducing the hydrocyanic acid emission amount in the mainstream smoke of cigarettes and a preparation method thereof. The filter additive material for selectively reducing the hydrocyanic acid emission amount in the mainstream smoke of cigarettes is characterized in that the filter additive material is a novel material that can effectively absorb acidic gas and is obtained by chemically modifying a porous material and introducing different alkali groups. The preparation method of the filter additive material comprises the following steps: respectively carrying out surface chemical modification on the selected porous carrier material with trimethylamine chloride acethydrazide or (2-bromomethyl)trimethyl ammonium bromide, soaking with sodium hydroxide solution, washing with water and drying to obtain the modified porous material containing ammonium hydroxide group. Adding the material in a cigarette filter rod can reducethe hydrocyanic acid content in the mainstream smoke of cigarette by more than 30%, and no negative influence is caused on the taste quality of cigarette, thus achieving the purpose of selectively reducing harm.

Description

technical field [0001] The invention relates to a filter tip additive material for selectively reducing the release of hydrocyanic acid in mainstream smoke of cigarettes, a preparation method and application thereof. Applying the material to cigarette filter rods can effectively reduce the content of hydrocyanic acid in mainstream smoke without negatively affecting the smoking quality of cigarettes. Background technique [0002] Hydrocyanic acid (HCN) is a highly volatile and highly toxic substance, and the poisoning effect is mainly through CN - occur. After hydrocyanic acid enters the human body, it dissociates into cyanide ion (CN - ), CN - It can inhibit the activity of 42 kinds of enzymes, and at the same time, it can combine with ferric cytochrome oxidase to generate cyanide ferric cytochrome oxidase and lose the function of transferring oxygen, causing tissue hypoxia and suffocation. Hydrocyanic acid in cigarettes is mainly derived from the oxidative decomposition...
