Problems solved by technology

These materials are some broad-spectrum adsorption materials, and the selectivity is not strong. While adsorbing the main volatile carbonyl compounds in the smoke, they also adsorb some flavor components in the smoke, which makes the sensory quality of cigarettes change greatly.

Abstract

A tobacco additive and the preparation method and application thereof for selectively reducing the amount of volatile carbonyl contained in the smoke of cigarette is characterized in that APTES, TEOA, SA and sodium hydroxide are reacted in ethanol / water to get the additive. The preparation method comprises stirring, crystallization, deacidification, cleaning and drying. The device puts the tobacco additive into the filter to selectively reduce the amount of volatile carbonyl contained in the smoke of cigarette, because amine functional group can react with carbonyl. Consequently the invention can reduce the danger of cigarette.

Description

technical field [0001] The present invention relates to the field of research on tobacco additives, in particular to a tobacco additive that selectively reduces volatile carbonyl compounds in cigarette smoke and its preparation method and application. Using the additive of the present invention to add to cigarette filters can selectively Reducing the content of volatile carbonyl compounds in mainstream cigarette smoke. Background technique [0002] Volatile carbonyl compounds are one of the main pollutants in the atmosphere. They play an important role in atmospheric chemistry. These pollutants are not only primary pollutants, but more importantly secondary pollutants. They are the main source of photochemical smog. ingredients. It has been proved that aldehydes and ketones in the atmosphere have a strong stimulating effect on human eyes, skin and respiratory tract, and formaldehyde and acrolein have carcinogenic effects on animals. The new clean air law of the United Stat...
