Problems solved by technology

However, most of the flavors and fragrances are easy to volatilize. When added to the cigarette filter, the flavors and fragrances are easy to volatilize and escape during the process of cigarette processing and transportation, so that the flavors and fragrances cannot be effectively released when the cigarette is smoked.

Abstract

The invention discloses a method for adsorbing and slowly releasing phenylethanol by Fe-based silkworm excrement biochar, and belongs to the technical field of carbon material application. The Fe-based silkworm excrement biochar is used as an adsorption material to adsorb phenylethanol under the conditions that the pressure is -0.08 Mpa and the temperature is 48-50 DEG C, desorption is carried outunder the conditions that the pressure is normal pressure and the temperature is 45-50 DEG C, and the Fe-based silkworm excrement biochar has very good adsorption capacity and slow release performance on phenylethanol. The adsorption and desorption conditions of using Fe-based silkworm excrement biochar for adsorbing and desorbing phenylethanol are consistent with those of essence and perfume ina cigarette filter tip, the actual production requirements of cigarettes are met, and the method is suitable for being popularized and applied in the tobacco industry.

Description

technical field [0001] The invention belongs to the technical field of carbon material application, and in particular relates to an adsorption and slow-release method of Fe-based silkworm excrement biochar to phenylethanol. Background technique [0002] Phenylethyl alcohol, colorless viscous liquid, boiling point 219°C, relative density 1.0230, refractive index 1.5310-1.5340. Phenylethyl alcohol is an edible flavor that is allowed to be used in my country. The dosage is based on normal production needs. It is mainly used to prepare honey, bread and berry flavors. Fragrance flavors such as floral flavors are widely used in the deployment of soap and cosmetic flavors. In addition, they are also widely used in the tobacco industry. [0003] In the tobacco industry, adding flavors and fragrances to cigarette filters can improve the physical and chemical properties of cigarettes, round out the taste of smoke, and reduce the irritation of smoke. Adding flavors and fragrances can ...
