Absorbing agent for reducing released amount of HCN and crotonaldehyde in mainstream smoke of cigarettes

Abstract

The invention belongs to the technical field of cigarette production and particularly relates to an absorbing agent for reducing the released amount of HCN (Hydrogen Cyanide) and crotonaldehyde in mainstream smoke of cigarettes. The absorbing agent belongs to a molecular-sieve and polyethersulfone composite material and is prepared by the following specific steps: preparation of molecular sieves ZSM-5 and MCM-41, modification of the molecular sieves and blended spinning and the like. The composite material provided by the invention has the advantages that the surface is loose and porous and contains a large amount of micropore, mesopore and macropore channel structures so as to be beneficial to improving the absorbing active sites and the transmission efficiency of absorbed substances; in the prepared composite material, the modified alkaline and transition metal ion dual-functionalized molecular sieve material better utilizes the weak acidity of the HCN and the complexing action of -CN, and is added in a cigarette filter according to the added amount of 20mg / p after being used for the cigarette filter to prepare a composite filter, so that the released amount of the HCN and the crotonaldehyde in the mainstream smoke of the cigarettes can be effectively reduced, and the promotion and application values are better.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, and in particular relates to an adsorbent for reducing the release of HCN and crotonaldehyde in mainstream smoke of cigarettes. Background technique [0002] Tobacco is one of the important economic crops in our country and occupies an important position in the national economy. However, as people pay more and more attention to health, the smoking safety of cigarettes has become a research hotspot in recent years, which has attracted great attention from governments all over the world. [0003] Hydrocyanic acid, one of the main harmful components in mainstream cigarette smoke, is an important environmental pollutant, and its toxic mechanism is: the combination of cyanide ion and ferric iron in oxidative cytochrome oxidase blocks the oxidation process The electron transfer of ferric iron in the medium makes the tissue cells unable to use oxygen, forming internal suffocation, coma, re...

AI Technical Summary

Problems solved by technology

[0005] In the existing technology, in order to reduce the release of harmful components in the mainstream smoke of cigarettes, it is usually carried out from many aspects such as filter tip processing and tobacco pretreatment, among which the development of new materials with adsorption and decomposition functions is also one of the commonly used harm reduction measures , but due to the long development cycle and certain variability of new harm-reducing and tar-reducing materials, it is difficult, especially for composite harm-reducing adsorbent materials that reduce the release of HCN and crotonaldehyde in mainstream cigarette smoke. In the research stage, further in-depth exploration and research are needed
