Embodiment 1

[0021] Tobacco extract residues described in this example, Zimbabwean tobacco leaves are used as raw materials after extraction, the remaining residues are filtered, microwaved at a microwave power of 350W for 15 minutes, and then the microwave-treated materials are dried at 50°C, crushed and sieved A 20-mesh powder was obtained.

[0022] The preparation method of the tobacco extract residue porous material of the present invention specifically comprises the following steps: mixing the 20-mesh Zimbabwean tobacco leaf extract residue powder with a mass ratio of 1:5 and a NaOH solution with a concentration of 5% at 30 ℃, 100r / min conditions for 5h, filtered, washed with distilled water until the pH value is neutral, and dried at 50 ℃ to constant weight. Then it was fully mixed with a 5mol / L phosphoric acid solution at a mass ratio of 1:10, heated in microwave for 20min, then filtered and washed with distilled water to remove the phosphoric acid solution until the pH value was ne...

Embodiment 2

[0031] Tobacco extract residues described in this example are extracted from tabacum tabacum leaves as raw materials, and the remaining residues are filtered, microwave-treated at a microwave power of 500W for 10 minutes, and then the microwave-treated materials are dried at 60°C and pulverized. Sieve to obtain 40 mesh powder.

[0032] The preparation method of the tobacco extract residue porous material of the present invention specifically includes the following steps: mixing the 40-mesh tobacco leaf extract residue powder with a mass ratio of 1:7 and a NaOH solution with a concentration of 10%. After treatment at 40°C and 110r / min for 4h, filter, wash with distilled water until the pH value is neutral, and dry at 60°C until constant weight. Then it was fully mixed with 4mol / L phosphoric acid solution at a mass ratio of 1:12, and heated in microwave for 25min, then filtered and washed with distilled water to remove the phosphoric acid solution until the pH value was neutral....

Embodiment 3

[0041] Tobacco extract residues described in this example are extracted from the tobacco leaves of Hongda and Zimbabwe, and the remaining residues are filtered, treated with microwaves at a microwave power of 700W for 5 minutes, and then dried at 70°C and pulverized. After sieving, a 60-mesh powder was obtained.

[0042] The preparation method of the tobacco extract residue porous material of the present invention specifically comprises the following steps: mixing 60-mesh Hongda and Zimbabwe tobacco leaf extract residue powder with a mass ratio of 1:10 and a NaOH solution with a concentration of 15%, After being treated at 50°C and 120r / min for 3h, it was filtered, washed with distilled water until the pH value was neutral, and then dried at 70°C to constant weight. Then it was fully mixed with 2mol / L phosphoric acid solution at a mass ratio of 1:13, and heated in microwave for 30min, then filtered and washed with distilled water to remove the phosphoric acid solution until th...

Abstract

The invention discloses a preparing method of a residue porous material obtained after tobacco extraction and further discloses application of the residue porous material obtained after tobacco extraction in being mixed into cigarette filters to depress tar and reduce harmful substances of cigarette smoke and / or increase wetness of smoke.

Description

technical field [0001] The invention relates to a residue porous material after tobacco extraction and its application, and belongs to the technical field of additive materials for cigarette mouthpieces. Background technique [0002] Tobacco flavor and fragrance technology is one of the important core technologies of the tobacco industry, and plays an indispensable role in the formation of Chinese-style cigarettes, especially low-tar cigarettes. Tobacco extracts, tobacco essential oils and tobacco extracts are practical and effective in various types of cigarettes, and play an important role in forming the unique aroma style and taste characteristics of cigarettes. [0003] The tobacco industry is also looking for materials that can effectively absorb tar and other harmful substances in cigarette smoke to achieve tar reduction and harm reduction. At present, the conventional filter material in the tobacco industry is cellulose acetate tow. Although it can effectively absorb...
