Embodiment 1
[0025] (1) Take 100 grams of tobacco stems with a chloride ion content of 2.61% and add them to a 2000 mL round bottom flask, add 5 times of 40% ethanol aqueous solution, stir and extract at 50°C for 20 minutes, then filter, and separate to obtain an extraction 365 grams of liquid and 235 grams of primary solids;
[0026] (2) Concentrate the primary extract to obtain a primary extract, adjust the pH of the primary extract to 10 with 5% aqueous sodium hydroxide solution, then extract with solvent dichloromethane to obtain crude nicotine, add malic acid to adjust the pH to 3 ~5% organic acid aqueous solution is back-extracted and concentrated to obtain 1.15 grams of organic acid nicotine;
[0027] (3) The primary solid part was dried to obtain 74.6 grams of absolute dry matter, and the chloride ion content in the absolute dry matter was detected to be 1.03%. After one extraction treatment, the chloride ion in tobacco stems decreased by 60.5%;
[0028] (4) Extract the dry produ...
Embodiment 2
[0031] (1) Take 100 grams of tobacco stems with a chloride ion content of 2.61% and add them to a 2000 mL round bottom flask, add 3 times of 60% ethanol aqueous solution, stir and extract at 60°C for 15 minutes, then filter, and separate to obtain an extraction 374 grams of liquid and 226 grams of primary solid part;
[0032] (2) Concentrate the primary extract to obtain a primary extract, adjust the pH of the primary extract to 8 with 5% aqueous sodium hydroxide solution, then extract with solvent dichloromethane to obtain crude nicotine, add malic acid to adjust the pH to 3 ~4 organic acid aqueous solution was back-extracted and concentrated to obtain 1.32 grams of organic acid nicotine;
[0033] (3) The primary solid part was dried to obtain 76.1 grams of absolute dry matter, and the chloride ion content in the absolute dry matter was detected to be 1.10%. After one extraction treatment, the chloride ion in tobacco stems decreased by 57.8%;
[0034] (4) Extract the absolu...
Embodiment 3
[0037] (1) Take 100 grams of tobacco stems with a chloride ion content of 2.61% and add them to a 2000 mL round bottom flask, add 2 times of 80% ethanol aqueous solution, stir and extract at 30°C for 10 minutes, then filter, and separate to obtain an extraction Liquid 437 g and a solid part;
[0038] (2) Concentrate 200 grams of primary extract to obtain 22.3 grams of primary extract, measure its water content to 64%, detect the chloride ion content of the extract as 7.17% on an absolute dry basis, and remove 1.26 grams of chloride ions in total; Use 5% sodium hydroxide aqueous solution to adjust the pH value to about 9, then extract with solvent dichloromethane to obtain crude nicotine, add malic acid to adjust the pH to 4-5 organic acid aqueous solution for back extraction, and concentrate to obtain organic acid nicotine 2.27 grams of alkali;
[0039](3) Extract the primary solid part obtained in step (1) with 7 times of water at 60 °C for 30 minutes, and separate to obtain...
