Additive agent selectively reducing aldehydes matter in cigarette flue gas, production method and application thereof

Abstract

The invention discloses an additive to selectively lower the aldehydes substances in cigarette smoke, which uses the silica gel with thick holes as the carrier and introduces the functional group through modification to coat a layer of chemical compounds provided with amidogen, carbamido or amide and capable of reacting with aldehydes substances on the carrier surface and the hole channel surface, wherein the modified carrier is applied in the cigarette filter up and can selectively lower the contents of the aldehyde substances in the cigarette smoke, such as formaldehyde, aldehyde, propanal,acrylic aldehyde, crotonaldehyde and the like.

Description

technical field

[0001] The invention belongs to the technical field of cigarette preparation, and in particular relates to an additive for selectively reducing aldehydes in cigarette smoke, a preparation method and application of the additive. Background technique

[0002] At present, at least 20 kinds of aldehydes and 6 kinds of ketones have been found in the gas phase of cigarette smoke. Some aldehydes and ketones in the gas phase of smoke are the result of direct transfer of tobacco components, and the highest content is formaldehyde, acetaldehyde, propionaldehyde and acrolein. , crotonaldehyde, furfural and acetone. Some of the volatile carbonyl compounds, especially formaldehyde, acrolein and crotonaldehyde, are toxins of respiratory cilia, which inhibit the removal of lung excretions after inhalation, which can lead to lung diseases.

[0003] In order to increase the smoking safety of cigarettes, various methods can be used to reduce harmful aldehydes in cigarette smo...
