Problems solved by technology

CN101336752A directly adds or adsorbs alkaline substances in the fiber substrate, but lacks selectivity for the removal of hydrogen cyanide
To sum up, the current research has a certain effect on reducing the release of hydrogen cyanide in the mainstream smoke of cigarettes, but there are also problems such as weak selective adsorption of hydrogen cyanide, affecting the sensory quality of cigarettes, and the cost of harm reduction materials is expensive and difficulty in industrialization and many other problems, so it has not really been widely used

Embodiment 1

[0017] Example 1. Wash, degas, dry, pulverize and sieve Radix Radix to prepare (20 mesh-100 mesh) granules; add 10g of Radix Radix to 30g of anhydrous pyridine, then slowly add 10g of succinic anhydride, and after reflux for 5 hours, Cool to room temperature, filter with suction and wash with anhydrous pyridine, dry at 60°C for 12 hours, and sieve to select product particles of 20 mesh to 100 mesh. Take 5 g of the carboxylated product, add it to 100 mL of 0.2 mol / L ferric chloride aqueous solution, react at room temperature for 4 hours, dehydrate, wash with water, dry at 60°C for 12 hours, sieve, and select product particles of 20 mesh to 100 mesh to obtain materials needed.

Embodiment 2

[0018] Example 2. Wash the poria cocos, remove impurities, dry, pulverize and sieve to prepare (20 mesh-100 mesh) granules; add 10g of poria cocos granules to 40g of anhydrous pyridine, then slowly add 20g of maleic anhydride, and reflux reaction After 6 hours, cool to room temperature, filter with suction and wash with anhydrous pyridine, dry at 60°C for 12 hours, and sieve to select product particles of 20 mesh to 100 mesh. Take 5 g of the carboxylated product, add it to 200 mL of 0.1 mol / L ferric sulfate aqueous solution, react at room temperature for 5 hours, dehydrate, wash with water, dry at 60°C for 12 hours, sieve, and select 20 mesh-100 mesh product particles to obtain the obtained Need materials.

Embodiment 3

[0019] Example 3. Remove the sponge from the corn cob, wash, remove impurities, dry, crush and sieve to prepare (20 mesh-100 mesh) granules; add 10g corn cob granules to 50g anhydrous pyridine, and then slowly add 20g Phthalic anhydride, after reflux reaction for 5 hours, cooled to room temperature, suction filtered and washed with anhydrous pyridine, dried at 60°C for 12 hours, sieved, and selected 20 mesh-100 mesh product particles. Take 5 g of the carboxylated product, add it to 200 mL of 0.15 mol / L copper sulfate aqueous solution, react at room temperature for 4 hours, dehydrate, wash with water, dry at 60°C for 12 hours, sieve, and select 20-100 mesh product particles to obtain the obtained Need materials.

Abstract

A modified natural plant-based filter additive material that selectively reduces the hydrogen cyanide release in mainstream cigarette smoke and a preparation method thereof. The natural plant-based material is used as a carrier, which is prepared by carboxylation and loading transition metal ions in sequence. become. In the present invention, the filter tip additive material prepared by using natural plant material as a carrier has porous adsorption properties and is rich in transition metal ions. Since CN- has a strong complexation effect with transition metal ions, the filter tip additive material of the present invention can effectively absorb and complex hydrogen cyanide, thereby selectively reducing the amount of hydrogen cyanide released in mainstream cigarette smoke the goal of. The invention has wide sources of raw materials and is environmentally friendly, and the prepared filter tip additive material has high safety, simple preparation process, low cost and easy realization of large-scale production. Applying the material to cigarette filters can selectively reduce the amount of hydrogen cyanide released in cigarette mainstream smoke by more than 35%, while having no negative impact on the sensory quality of cigarettes.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and relates to a modified natural plant filter additive material for selectively reducing the hydrogen cyanide release in mainstream smoke of cigarettes and a preparation method thereof. Applying the material to cigarette filter rods can effectively and selectively reduce the amount of hydrogen cyanide released in mainstream smoke of cigarettes without negatively affecting the sensory quality of cigarettes. Background technique [0002] Hydrogen cyanide is an important harmful component in cigarette smoke and one of the seven representative harmful components in mainstream cigarette smoke. All phases are distributed, and the gas / particle ratio is generally greater than 1:1. Hydrogen cyanide is the most toxic substance in cigarette smoke. Hydrogen cyanide in the smoke quickly enters the body after being absorbed by the respiratory tract, causing harm to human health. Therefore, it is of great...
