Embodiment 1

[0034] This embodiment provides the degree of reduction of harmful substances when 4 kinds of pyruvic acid compounds are present in 4 cigarette filters in a uniformly dispersed state, and the uniformly dispersed state is shown in figure 1 . The cigarette of present embodiment adopts the cigarette of certain brand, and filter tip is 3 centimeters long, and diameter is 8 millimeters, and cigarette filter tip part is cut off, and the amount fraction of immersing substance is 6% pyruvic acid solution, 6% sodium pyruvate respectively solution, 6% magnesium pyruvate solution, and 6% calcium pyruvate solution were taken out and vacuum-dried to constant weight at room temperature. Among them, the additives pyruvate, sodium pyruvate, magnesium pyruvate, and calcium pyruvate exist in a solid state of dispersion and are not fixed on the cigarette filter at all, and the particle size of the additive is less than 0.6 mm. Then connect the treated filter tip to the shredded tobacco with a s...

Embodiment 2

[0041] This embodiment provides the degree of reduction of harmful substances when different contents of sodium pyruvate exist in a uniformly dispersed state in cigarette filters, see figure 1 . Using a certain brand of cigarettes, the filter tip is 3 cm long and 8 mm in diameter. Cut off the filter tip of the cigarette and immerse it in 1% sodium pyruvate solution, 6% sodium pyruvate solution, and 12% sodium pyruvate solution respectively. Sodium pyruvate solution and 18% sodium pyruvate solution were taken out and vacuum-dried to constant weight at room temperature. Wherein, the additive sodium pyruvate exists in a solid dispersion state and is not fixed on the cigarette filter at all, the amount of the additive is between 0.05mg-1.2g, and the particle diameter of the additive is less than 0.6mm. Then connect the treated filter tip to the shredded tobacco with a short glass tube, the weight of the shredded tobacco is 600±10mg, and use the untreated filter cigarette of the s...

Embodiment 3

[0049] This example provides the degree of reduction of harmful substances when sodium pyruvate and activated carbon are used in combination in cigarette filters. Adopt a certain brand of cigarette, the filter tip is 3 centimeters long, and the diameter is 8 millimeters, and the cigarette filter tip part is cut off, and the sodium pyruvate solution of immersion material fraction 6% is vacuum-dried to constant weight under normal temperature after taking out. Cut the filter tip from the middle, spread 1mm thick activated carbon on the cut place, and then connect the filter tip with a short glass tube. Wherein, the additive sodium pyruvate exists in a solid dispersion state and is not fixed on the cigarette filter at all, the amount of sodium pyruvate is between 0.05mg-1.2g, and the particle size of sodium pyruvate is less than 0.6mm. The additive activated carbon exists in a state of layered aggregates and is not fixed on the cigarette filter at all, see figure 2 . Then conn...

Abstract

The invention provides an application of a pyruvic acid compound in cigarette filter tip preparation as an additive for reducing the inhalation amount of harmful substances in smoke. Compared with the prior art, the application of the invention has the characteristics as follows: (1) a small-molecule compound is adopted to react with harmful substances, so that the harmful substances are absorbed, part of the harmful substances is removed efficiently, and the combustion performance of cigarettes is not affected; (2) a small amount of pyruvic acid compound is consumed, and the cost is low; and (3) the pyruvic acid compound in an abandoned filter tip is easily degradable, and does not cause great harm to the environment.

Description

technical field [0001] The patent of the invention relates to the application of pyruvate compounds as cigarette filter additives for reducing the intake of harmful substances in smoke, and belongs to the technical field of cigarette filters. Background technique [0002] There are thousands of harmful substances in the smoke produced by burning cigarettes, including gas phase and particulate phase substances. Among them, nicotine, tar, carbon monoxide, nitrosamines, aldehydes, radioactive substances, arsenic, cadmium, cyanide, free radicals etc. Nicotine is the main dependent substance of smoking addiction, and it can also promote the proliferation of cancer cells. Tar contains multiple carcinogens, of which benzopyrene is one of the most typical three-causing (carcinogenic, teratogenic and mutagenic) poisons. Carbon monoxide makes people hypoxic, and nitrosamines are also typical triple poisons. [0003] According to public information, the methods to reduce the harm of ...
