Embodiment 1

[0026] A two-phase extraction method for nicotine, comprising the following steps:

[0027] Pretreatment: Grinding the collected tobacco, crushing the tobacco stems and tobacco leaves through a grinder, and then sieving for later use to obtain tobacco powder, leaching the tobacco powder, and mixing the tobacco powder with water at a ratio of 1:7 At this time, the temperature of the water needs to be kept at 60°C to obtain a tobacco solution, put the tobacco solution into a vertical leaching tank and let it stand for 10 minutes, then take it out and heat the tobacco solution to maintain its temperature at 60°C to obtain a high-temperature tobacco solution, Put the high-temperature tobacco solution into a horizontal spiral extractor to accelerate the leaching of the high-temperature tobacco solution, and last for 50 minutes to obtain a tobacco leaching solution.

[0028] Concentration treatment: put the tobacco extract into the multi-effect concentrator, control the vacuum degree ...

Embodiment 2

[0037] The two-phase extraction method of a kind of nicotine of this embodiment is the same as embodiment 1, and its difference is only, comprises the following steps:

[0038] Pretreatment: Grinding the collected tobacco, crushing the tobacco stems and tobacco leaves through a grinder, and then sieving for later use to obtain tobacco powder, leaching the tobacco powder, and mixing the tobacco powder with water at a ratio of 1:7 At this time, the temperature of the water needs to be kept at 20°C to obtain a tobacco solution, put the tobacco solution into a vertical leaching tank and let it stand for 10 minutes, then take it out and heat the tobacco solution to maintain its temperature at 30°C to obtain a high-temperature tobacco solution, The high-temperature tobacco solution is put into a horizontal spiral extractor to accelerate the leaching of the high-temperature tobacco solution, and lasts for 60 minutes to obtain a tobacco leaching solution.

Embodiment 3

[0048] The two-phase extraction method of a kind of nicotine of this embodiment is the same as embodiment 1, and its difference is only, comprises the following steps:

[0049] Pretreatment: Grinding the collected tobacco, crushing the tobacco stems and tobacco leaves through a grinder, and then sieving for later use to obtain tobacco powder, leaching the tobacco powder, and mixing the tobacco powder with water at a ratio of 1:7 At this time, the temperature of the water needs to be kept at 70°C to obtain a tobacco solution. Put the tobacco solution into a vertical leaching tank and let it stand for 10 minutes, then take it out and heat the tobacco solution to maintain its temperature at 70°C to obtain a high-temperature tobacco solution. Put the high-temperature tobacco solution into a horizontal spiral extractor to accelerate the leaching of the high-temperature tobacco solution, and last for 10 minutes to obtain a tobacco leaching solution.

Abstract

The invention discloses a two-phase extraction method of nicotine, and particularly relates to the technical field of two-phase extraction. According to the method, the obtained tobacco powder is put into a distillation device, a proper amount of liquid is added after the tobacco powder is put into the distillation device, the distillation device is started, the liquid is in a boiling state by increasing the temperature of the liquid in an accelerated mode, the internal pressure intensity of the distillation device is adjusted, and n-hexane or petroleum ether is added in the steam liquefaction process to serve as an extraction phase, and two-phase extraction of liquefied steam is achieved, the liquefied steam can be immediately enriched in the oil phase while nicotine is generated, the nicotine extract is obtained, only n-hexane or petroleum ether needs to be added to serve as an extraction phase in the method, target nicotine can be immediately enriched in the oil phase while the target nicotine is generated, and thus the effects that products can be separated and purified in time, and the reaction process is more efficient can be realized, generation of by-products is greatly reduced, tedious steps during nicotine extraction are reduced, and the nicotine extraction effect of the method is guaranteed.

Description

technical field [0001] The invention relates to the technical field of two-phase extraction, more specifically, the invention relates to a two-phase extraction method of nicotine. Background technique [0002] Natural tobacco leaves generally contain 1-3% nicotine. Nicotine is commonly known as nicotine. Adequate intake can stimulate the spirit, eliminate fatigue, increase thinking ability, improve work efficiency, and has a certain anesthetic effect. This is the reason why many smokers smoke. However, nicotine has certain toxicity, and excessive intake will damage human health, such as chronic pharyngitis, respiratory diseases, cardiovascular diseases, certain digestive tract diseases, headaches, insomnia and other nervous system disorders. In the current reality that it is impossible to completely quit smoking, regulating and reducing the nicotine content in ordinary cigarettes has become the goal pursued by the tobacco industry. In addition, in order to meet the differe...
