Problems solved by technology

However, the production cost is relatively high, and in the production process, there will be uneven distribution in a single cigarette, which is difficult to control
[0004] The above technologies can reduce tar and other harmful substances at the same time through the blocking and adsorption of solid substances, but the effect is not as obvious as reported when applied to medium and low tar cigarettes. The reduction rate of tar is higher than that of harmful substances, and cannot reach high Requirements for Selective Reduction of Harmful Components in Cigarette Smoke

Embodiment 1

[0024] Add N-methylimidazole, n-chlorobutane and toluene into the three-necked flask in sequence, and heat and stir for reaction. After the reaction is finished, it is washed and recrystallized, and the obtained product is dried in a vacuum oven. This gives 1-butyl-3-methylimidazole chloride (BMIC). Use ethanol as a solvent to prepare a solution with a mass fraction of 12%, and use the existing coating process to coat cellulose paper at a load of 5%, and dry it online at 85°C. The cellulose paper is used as The forming paper and the tow are prepared into a mouth stick, which is rolled up into a cigarette. The removal rates of the tar and hydrocyanic acid of the mouth stick are 0 and 23.7% respectively. After smoking the sample cigarettes, it basically does not change the taste of smoking.

Embodiment 2

[0026] Under nitrogen protection, 1-methylimidazole and γ-chloropropyltrimethoxysilane were refluxed at 65°C for 72h to obtain an ionic liquid, which was prepared into a solution with a mass fraction of 12% using ethanol as a solvent. According to the coating process of 5% load, it is coated on cellulose paper and dried on-line at 85°C. The cellulose paper is used as forming paper and tow to prepare mouth rods, which are wound into cigarettes. The removal rates of tar and hydrocyanic acid were 0 and 37.4%, respectively.

Embodiment 3

[0028] Under nitrogen protection, 1-methylimidazole and γ-chloropropyltrimethoxysilane were refluxed at 65°C for 72h to obtain an ionic liquid, which was prepared into a solution with a mass fraction of 12% using ethanol as a solvent. According to the coating process of 3% load, it is coated on the cellulose paper, and it is dried on-line at 85°C. The cellulose paper is used as forming paper and tow to prepare a mouth rod, which is wound into a cigarette. The mouth rod The removal rates of tar oil and hydrocyanic acid are 1.4% and 32.4% respectively.

Abstract

The invention provides cellulose paper for reducing formonitrile content of cigarette smoke. Forming paper of the cellulose paper loaded with ionic liquid is applied to an acetate fiber filter tip to reduce the formonitrile content of the cigarette smoke obviously and selectively, and the mouthfeel of cigarettes is not influenced while the harm to smokers is reduced. The cellulose paper has the advantages of simple preparation technology, convenient addition and suitability for the requirement of industrial production.

Description

technical field [0001] The invention belongs to the technical field of cigarette preparation, and in particular relates to a cellulose paper for reducing the content of hydrocyanic acid in cigarette smoke, a preparation method and an application thereof. Background technique [0002] Hydrogen cyanide is a colorless or light blue liquid or gas with a slightly bitter taste and an almond-like odor. It is easily soluble in water, ethanol, and slightly soluble in ether. Its aqueous solution is weakly acidic, and it is a highly volatile Class A Highly toxic, hydrocyanic acid in cigarettes is mainly produced by the cracking of amino acids and related compounds at 700-1000°C, with a content of about 30-200 μg / cigarette. After inhalation, HCN can be combined with ferric cytochrome oxidase in the body to become Cytochrome oxidase with high ferric cyanide loses the function of transmitting itching, causing tissue hypoxia and poisoning, which is extremely harmful to the human body. The...
