Two-phase extraction method of nicotine

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...

Problems solved by technology

[0008] In order to overcome the above-mentioned defects of the prior art, the invention provides a two-phase extraction method of nicotine. The technical problem to be solved by the invention is: currently in the process of extracting nicotine, it is necessary to extract the nicotine The extraction agent is used to assist the extraction of nicotine. However, after the extraction is completed, secondary separation or subsequent separation steps are required to distinguish nicotine and impurities, which leads to a cumbersome extraction process of nicotine in the actual operation process. It is difficult to achieve enrichment in oil items, resulting in the separation and purification of the product to be divided into multiple steps, which greatly increases the reaction time and the complexity of extracting nicotine. At the same time, adding a variety of reactants is likely to cause nicotine Problems with increased by-product generation in extraction
