Embodiment 1
[0034] The pyrolysis product of tobacco leaf extract provided in this example is prepared by the following steps.
[0035] (1) Preparation of tobacco leaf extract
[0036] Take 30kg of tobacco leaves and grind them through a 20-mesh sieve, add 600L of extraction solvent ethanol (80% ethanol v / v), heat and reflux for 3 hours, filter, concentrate under reduced pressure until no more liquid flows out, and obtain 7.08kg of tobacco leaf extract;
[0037] The tobacco leaves are Luzhou-flavor tobacco leaves, specifically the tobacco leaves of China Tobacco 100B2F in Jiaxian County, Henan Province.
[0038] (2) cracking the tobacco leaf extract
[0039] Place the tobacco leaf extract prepared in step (1) in a cracking furnace, the side wall of the cracking furnace is connected to a receiving bottle through a connecting pipe, and the receiving bottle contains 3L of absorption solvent ethanol;
[0040] Introduce high-purity nitrogen (that is, neither oxygen nor hydrogen), adjust the n...
Embodiment 2
[0052] The pyrolysis product of tobacco leaf extract provided in this example is prepared by the following steps.
[0053] (1) Preparation of tobacco leaf extract
[0054] The prepared tobacco leaf extract is the same as in Example 1.
[0055] (2) cracking the tobacco leaf extract
[0056] The prepared tobacco leaf extract is placed in a cracking furnace, the side wall of the cracking furnace is connected with a receiving bottle through a connecting pipe, and 3L of absorption solvent n-hexane is filled in the receiving bottle;
[0057] Introduce nitrogen with an oxygen content of 10%, adjust the gas flow rate to 10L / min, and after passing the mixed gas for 5 minutes, the temperature of the cracking furnace is rapidly raised to 650°C, and the heating is stopped after 2 minutes of thermal cracking.
[0058] (3) Vacuum rotary evaporation concentration
[0059] Place the receiving bottle containing the cleavage product obtained in step (2) under vacuum at 25°C, and carry out va...
Embodiment 3
[0063] The pyrolysis product of tobacco leaf extract provided in this example is prepared by the following steps.
[0064] (1) Preparation of tobacco leaf extract
[0065] The prepared tobacco leaf extract is the same as in Example 1.
[0066] (2) cracking the tobacco leaf extract
[0067] The tobacco leaf extract is placed in the cracking furnace, the side wall of the cracking furnace is connected with a receiving bottle through a connecting pipe, and 3L of absorption solvent acetone is contained in the receiving bottle;
[0068] Introduce nitrogen gas with a hydrogen content of 8%, adjust the gas flow rate to 12L / min, and after introducing the mixed gas for 5 minutes, the temperature of the cracking furnace is rapidly raised to 750°C, and the heating is stopped after 1.5 minutes of thermal cracking.
[0069] (3) Vacuum rotary evaporation concentration
[0070] Place the receiving bottle containing the cleavage product obtained in step (2) under vacuum at 25°C, and carry o...
