Problems solved by technology

[0005] However, the time for the smoke to pass through the filter is very short, and at the same time the components in the smoke are mixed together and pass through the filter in the form of aerosols.
In addition to improving the taste or irritation, the existing additives cannot effectively remove harmful substances in the smoke, and the preparation process is complicated, which cannot quickly and selectively reduce the phenol content in the smoke

Abstract

The invention relates to a compound additive for reducing the release amount of phenol in flue gas and a preparation method and application thereof. The compound additive comprises, by weight, 1-20 parts of polymers, 0.1-5 parts of acid compounds, 0.1-5 parts of polyol and 20-50 parts of solvents; and the polymers are one or more of polyvinyl pyrrolidone and vinyl pyrrolidone-maleic acid copolymers with the molecular weight of 1,000 to 1,000,000. Suitable ligands are selected to be mixed with PVP, the amount of phenol in the flue gas is quickly and selectively reduced, the effect is obvious, the smoke flavor of cigarettes is not obviously affected, and the irritation is relieved. The preparation method is simple, the cost is low, and the harm reduction effect is obvious.

Description

technical field [0001] The invention relates to a compound additive, in particular to a compound additive for reducing the release of phenol in smoke, and also relates to a preparation method and application thereof, belonging to the field of cigarettes. Background technique [0002] Since the early 1950s, when the Royal Society of Medicine first reported the official report on the health hazards of smoking, smoking and health issues have always been highly valued by governments, the tobacco industry and the medical profession. In recent years, with the active promotion of the World Health Organization (WHO), many governments and various anti-smoking groups, the "Framework Convention on Tobacco Control" formulated by WHO not only stipulates that governments should adopt and implement effective legislation, administration and Other measures prevent and reduce tobacco consumption, nicotine addiction and exposure to tobacco smoke, etc., and also require restrictions on the cont...
