Problems solved by technology

For example, in the patent CN1413529A, adsorbents such as activated carbon and charcoal are used, which claim that tar and nicotine are well absorbed; and benzopyrene can also be reduced in multiples; in CN1424879A, Jin Renzai and others have invented a method for treating tobacco leaves with water and alcohol, which is said to be able to reduce multiple harmful components in the smoke; yet they are all unsatisfactory Selectively reduce the nicotine content, greatly changing the original flavor of cigarettes
In addition, patents such as CN1408291A, CN1457709A, and CN1160515A all use different kinds of Chinese herbal medicines as tobacco substitutes. In this case, the nicotine content is extremely low or even does not contain nicotine, but at the same time, it cannot provide any tobacco flavor or taste, so it is difficult to be consumed accept

Abstract

The present invention discloses one kind of molecular engram material for lowering nicotine content in cigarette fume and its application. Before synthesizing molecular engram material, nicotine is first mixed with functional monomer for mutual reaction to form molecular compound, then reacted with added cross-linking agent to form high cross-linked high molecular material, and finally eliminated chemically or physically from the high molecular material. In the polymer, great amount of holes possessing high selectivity on nicotine molecule are formed. The molecular engram material is preferably applied in composite filter tip to reduce nicotine content in cigarette fume and reach the selective harm reducing aim.

Description

technical field [0001] The invention relates to a molecularly imprinted material and an application method for selectively reducing the nicotine content in cigarette smoke. Background technique [0002] Tobacco reduction and harm reduction is an important issue related to the health of smokers. For many years, various tobacco research institutions have been committed to the research of this work, and have achieved a large number of research results. The harmful components in smoke have been relatively greatly reduced. However, the selectivity of using these means to reduce harm is not high, which partially affects the original style and taste of cigarettes. Therefore, selective harm reduction has become a major development trend of cigarette industry harm reduction. [0003] A large number of research results have shown that nicotine is the main pharmacological factor causing tobacco use, that is, nicotine is addictive. At the same time, nicotine itself has great toxicity. ...
