Embodiment 1
[0023] Take 100g of tobacco with a particle size of 20 meshes, add 1-butyl-3-methylimidazolium chloride salt equivalent to 10 times the mass of tobacco, and carry out a dissolution reaction at 100°C for 4 hours to obtain a reaction solution. Liquid is carried out solid-liquid separation, gets liquid, and described liquid is cellulose solution; Add the deionized water that volume is 3 times in gained cellulose solution, filter after stirring for 30 minutes, gained filter residue is cellulose, and cellulose quality is 9.6g, the cellulose yield is 43.63%.
Embodiment 2
[0025] Accurately weigh 170 g of NaOH and dissolve it in 510 mL of distilled water to prepare a NaOH solution with a mass concentration of 25%. Weigh 120g of tobacco with a particle size of 20 mesh and put it into a three-necked bottle, then add 500mL of NaOH solution with a mass concentration of 25%, and stir it mechanically for 1 hour. After the reaction, wash and filter with distilled water until the filtrate is neutral. The filter residue was vacuum-dried at 70°C for later use. Take 100g of tobacco with a particle size of 20 meshes, add 1-butyl-3-methylimidazolium chloride salt equivalent to 10 times the mass of tobacco, and carry out a dissolution reaction at 100°C for 4 hours to obtain a reaction solution. Liquid is carried out solid-liquid separation, gets liquid, and described liquid is cellulose solution; Add the deionized water that volume is 5 times in gained cellulose solution, filter after stirring for 30 minutes, gained filter residue is cellulose, and cellulose ...
Embodiment 3
[0027] Weigh 120g of tobacco with a particle size of 20 mesh and put it into a three-neck bottle, then add 500mL of hydrochloric acid solution with a mass concentration of 10%, and stir it mechanically for 1.5h. After the reaction, wash and filter with distilled water until the filtrate is neutral. . The filter residue was vacuum-dried at 70°C for later use. Take 100g of tobacco with a particle size of 20 meshes, add 1-butyl-3-methylimidazolium chloride salt equivalent to 10 times the mass of tobacco, and carry out a dissolution reaction at 100°C for 4 hours to obtain a reaction solution. Liquid is carried out solid-liquid separation, gets liquid, and described liquid is cellulose solution; Add the deionized water that volume is 3 times in gained cellulose solution, filter after stirring for 30 minutes, gained filter residue is cellulose, and cellulose quality is 19.5g, which is 45.01% higher than the untreated raw cellulose, and the cellulose yield is 88.64%.
