Abstract

The invention relates to a molecularly imprinted material for selectively reducing TSNA content in cigarette smoke and the application thereof. The molecularly imprinted material is prepared as follows: before synthesizing the molecularly imprinted material, template molecules are mixed with functional monomers which can generate intermolecular force with the template molecules in order to generate interaction and form molecule complex; then a cross linker is added to form a highly cross-linking polymer material; then the template molecules are removed from the polymer material by chemical or physical methods. A plurality of cavities which can match with the space of the template molecules and has multi-functional sites arranged specifically are formed in the polymer; the cavities has effective selectivity to TSNA molecule. When being used for the alternative damage-reduce of cigarette smoke, the invention is best used in a composite mouth wand, and the added amount of the invention can be freely regulated according to needs. The invented substance can be added to the mouth wand according to the standard of 40mg per cigarette and can reduce the TSNA content of smoke by 24.6 percent without impacting the other components of the smoke, thereby realizing alternative damage-reduce.

Description

technical field [0001] The invention relates to a molecularly imprinted material and an application method for selectively reducing the content of TSNA (tobacco-specific nitrosamine) 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] The research on tobacco-specific nitrosamines (TSNAs) was first started in the early 1960s. According to reports, eight kinds of tobacco-specific nitrosamines have been iden...
