Problems solved by technology

[0005] In the process of production, packaging and transportation, there are several troublesome problems: ①Usually, when dilute sulfuric acid is used for back extraction and enrichment, nicotine removal can be enriched In addition, other impurities will also dissolve in the acid at the same time, thus affecting the quality of the final product; ② Dilute sulfuric acid is generally obtained by diluting concentrated sulfuric acid, and there is a certain risk in the dilution process; ③ The product is liquid, and the storage time is slightly longer ( 2, 3 days), there are differences in the content of the upper, middle and lower parts (the more there are 3-5 points); ④The usual packaging for this product is a 200L standard iron drum, and it must be sprayed with PVF inside for anti-corrosion. The gross weight of a drum is about 222kg, and the net weight 200kg, it is troublesome to carry, and it is even more troublesome when getting on and off the bus; ⑤Generally speaking, 40% nicotine sulfate is called a crude product, and it needs to be further processed by the terminal manufacturer, which will generate a large amount of waste liquid and bring environmental problems
, the existing technology has the characteristics that the extraction process is relatively complicated, it is not conducive to storage and transportation, and it is volatile, and the nicotine after volatilization is also relatively harmful to the human body

Embodiment 1

[0025] Such as figure 1 A method for producing solid nicotine is shown. The technology includes freeing nicotine, extracting nicotine, stripping nicotine, separating the extract, testing, and obtaining solid nicotine. The specific steps are as follows:

[0026] Free nicotine: the nicotine-containing material is alkalized to obtain free nicotine;

[0027] Extract nicotine: add 6# solvent oil to free nicotine to extract nicotine;

[0028] Back extraction of nicotine: place oxalic acid crystal particles in the screen, put the screen into 6# solvent oil extracted with nicotine, and carry out back extraction, 6# solvent oil flows continuously relative to the screen, and carry out back extraction of nicotine ;

[0029] Separation of extraction liquid: After the nicotine in 6# solvent oil is back-extracted by oxalic acid crystals, 6# solvent oil continues to circulate back to the second step for recycling;

[0030] Inspection: Take out the oxalic acid crystal and dissolv...

Abstract

The invention discloses a solid nicotine production method. The technology includes free nicotine, extracting nicotine, back-extracting nicotine, separating the extraction liquid, testing, and obtaining solid nicotine. The extraction equipment required for this technology is simple and the extraction process can be When carried out at normal temperature and pressure, solid nicotine can be obtained directly, and the processing technology is simpler. The intermediate extract during the extraction process can be recycled multiple times. The production raw materials used are easy to obtain and are suitable for large-scale promotion and use.

Description

technical field [0001] The invention relates to a method for extracting heterocyclic compounds directly connected by ring atom-ring atom bonds in chemical organic chemistry, especially a method for producing solid nicotine. Background technique [0002] Tobacco is grown in many areas of our country. Most of the qualified tobacco leaves harvested by tobacco farmers are sold directly to tobacco companies, but most of the tobacco stems and inferior tobacco leaves are left every year. Due to the improvement of living standards, these remaining parts are no longer used. Household fire needs a suitable biogas digester if it is put into a biogas digester, and burning in the wild brings safety hazards and environmental pollution. [0003] In the prior art, the above-mentioned remaining materials can be used to extract nicotine, that is, nicotine, and nicotine is an important part of smoking cessation medicine and green environmental protection insecticide. A small amount of nicotin...
