Embodiment 1

[0027] Mix 0.005mol manganese nitrate, 0.05mol cerium nitrate and 100mL deionized water uniformly, add 160mL1.0mol / L potassium hydroxide solution dropwise, keep it under stirring for 1 hour, suction filter, wash with deionized water 3 times, and dry Dry in a box at 80°C for 12 hours, calcinate in a muffle furnace at 550°C for 2 hours, cool to room temperature naturally, then mix it with 170g chitosan, add 50mL 0.5mol / L potassium chloride solution, stir, Dry under a lamp, sieve to remove fine powder, take 40-60 mesh particles for later use.

[0028] The prepared additive was added to the cigarette filter at a rate of 40 mg / piece, and the filter without adding the filter rod additive of the present invention was used as a control. The smoke test results showed that the filter rod additive of the present invention can effectively reduce smoke compared with the control sample. The phenol content is 10.8%.

Embodiment 2

[0030] Mix 0.005mol manganese nitrate, 0.05mol cerium nitrate and 100mL deionized water uniformly, add 160mL 1.0mol / L potassium hydroxide solution dropwise, keep for 2 hours under stirring, suction filter, wash with deionized water 3 times, and dry Dry in a box at 100°C for 10 hours, calcinate in a muffle furnace at 500°C for 4 hours, cool to room temperature naturally, then mix it with 150g chitosan, add 50mL 0.5mol / L potassium chloride solution, stir, Dry under a lamp, sieve to remove fine powder, and take 40-60 mesh particles for later use.

[0031] The prepared additive was added to the cigarette filter at 30 mg / piece, and the filter without the filter rod additive of the present invention was used as a control. The smoke test results showed that the filter rod additive of the present invention can effectively reduce smoke compared with the control sample. The phenol content is 9.6%.

Embodiment 3

[0033] Mix 0.005mol manganese nitrate, 0.05mol cerium nitrate and 100mL deionized water uniformly, add 160mL1.0mol / L potassium hydroxide solution dropwise, keep it under stirring for 1 hour, suction filter, wash with deionized water 3 times, and dry Dry in a box at 120°C for 8 hours, calcinate in a muffle furnace at 450°C for 3 hours, cool to room temperature naturally, then mix it with 180g chitosan, add 50mL 0.5mol / L potassium chloride solution, stir, Dry under a lamp, sieve to remove fine powder, take 40-60 mesh particles for later use.

[0034] The prepared additive was added to the cigarette filter at a rate of 20 mg / piece, and the filter without the filter rod additive of the present invention was used as a control. The smoke test results showed that the filter rod additive of the present invention can effectively reduce smoke compared with the control sample. The phenol content is 8.8%.

Abstract

The invention discloses a filter stick additive with the function of reducing the content of phenol in the cigarette mainstream smoke and a preparation method and application thereof. The additive is a composite material prepared by loading Mn-Ce oxide with potassium ions on carriers. The method includes dissolving soluble manganese salts and cerium salt in water, adding alkali solution in a dripped manner to obtain precipitation through reaction, filtering, and obtaining Mn-Ce oxide by drying and calcining the precipitate; after mixing the Mn-Ce oxide with the carriers evenly, adding potassium chloride solution, mixing evenly, drying, and obtaining the filter stick additive. The filter stick additive has high chemical stability, and the content of phenol in the cigarette smoke can be reduced; in addition, the the preparation process and operation of the filter stick additive are simple, cost is low, and the industrial production requirements can be met.

Description

Technical field [0001] The invention relates to a filter rod additive with the function of reducing the content of phenol in mainstream cigarette smoke, and a preparation method and application thereof, belonging to the field of cigarette manufacturing. Background technique [0002] Cigarette combustion is a complex reaction. As one of the main components in smoke, there are 40 kinds of phenolic compounds, the most important of which are phenol and catechol. The phenolic compounds in cigarette smoke mainly come from tobacco leaves. The cleavage of phenolic compounds (chlorogenic acid and rutin), there is evidence that the presence of phenolic substances can significantly improve the carcinogenic activity of polycyclic aromatic hydrocarbons, especially phenol, o-, m, and hydroquinone, o, m, and p These phenols of cresol are harmful. Among them, the catechol in the flue gas condensate can help promote cancer, and some phenols have a strong stimulating effect on the skin and respira...
