Abstract
The present invention be a kind of from tobacco the method for extraction nicotine, tobacco is soaked in basic solution, made nicotine enter immersion liquid, with extraction agent nicotine is extracted again, use the nicotine in the acids solution absorption extraction agent then, obtain nicotine salt solution, remove acid group in the nicotine salt solution, obtain the nicotine aqueous solution through purifying with hydrated barta, extract with extraction agent again, obtain the saturated extraction agent of nicotine, saturated extraction agent carried out multi-effect distilling, get final product pure nicotine.
Description
The present invention relates to a kind of from tobacco the method for extraction nicotine, belong to the chemical treatment field of tobacco.
The place of China plantation tobacco is a lot, some inferior tobacco can't utilize, in making the pipe tobacco process, also there are a large amount of cigarette muscle to be removed simultaneously, these inferior tobaccos and cigarette muscle all go out of use and have wasted, contain 1.5~3% nicotine in tobacco leaf and the cigarette muscle, nicotine belongs to nitrogenous alkaloid, have been widely used in fields such as medicine, agricultural chemicals, scientific research, cigarette, national defence, therefore, extraction nicotine progressively obtains people's attention from tobacco leaf and cigarette muscle, but do not produce sophisticated production technique so far as yet, can't form the above industrial production of whole examination scale level.
The object of the present invention is to provide and a kind ofly can carry out the extraction nicotine salt from tobacco of technical scale lot production and the method for pure nicotine, and the product purity height, color and taste just, quality is good.
The present invention realizes like this, certain hour is soaked in the tobacco fragmentation in basic solution, make nicotine enter immersion liquid, nicotine is extracted through breakdown of emulsion with extraction agent again and use contained nicotine in the acids solution absorption extraction agent then, obtain nicotine salt solution, remove acid group in the nicotine salt solution with hydrated barta, obtain the nicotine aqueous solution, reduce its pigment content and reject peculiar smell with gac again, carry out the extraction second time with extraction agent again, the saturated extraction agent of the nicotine that is purified carries out multi-effect distilling to this saturated extraction agent, can obtain pure nicotine.
Accompanying drawing 1 is a process flow sheet of the present invention.
Now the present invention is described in detail in conjunction with the accompanying drawings:
1, cigarette muscle and inferior tobacco being crushed to the length of side is 0.2 or the cubes of 0.3mm, the aqueous solution (the pH value is 12) with basic solution such as sodium hydroxide or calcium hydroxide soaks, and solid-to-liquid ratio is 1: 7, soaks 6~12 hours, the nicotine leaching yield can reach more than 90%, obtains nicotine-containing immersion liquid thus.
2, solid-liquid separation: the residue after the water flushing is soaked, push residue again, the immersion liquid of soaking, wash, pushing gained is mixed, filter with the Plate Filtration method again, obtain filtrate.
3, make extraction agent with hydrochloric ether or blended organic solvent (as trieline and kerosene), in the spray-type extraction tower, nicotine-containing filtrate is extracted, dose method with mechanical process again or distillation method is abolished the emulsification that produces in the extraction process.The percentage extraction that nicotine enters extraction agent can reach 80~90%.
4, absorb contained nicotine in the extraction agent with 0.5~1 normal acids solution (as dilute hydrochloric acid or dilute sulphuric acid), the pH value that absorbs acids solution reaches till 4, can obtain nicotine salt solution.As with this nicotine salt solution at negative pressure 400~600mmHg, distill under 70~85 ℃ of conditions of temperature, promptly obtain the nicotine salt of content more than 40%, be nicotine salt finished product (general international standard), the work in-process of pure nicotine.
5, remove acid group in the nicotine salt solution with hydrated barta, obtain the nicotine aqueous solution, with vacuum filtration process that the filter of the nicotine aqueous solution is clean then.
6, with the active carbon purifying nicotine aqueous solution, weight ratio is that gac equals 1 to 25 than the nicotine aqueous solution, to reduce pigment content, rejects peculiar smell, filters the nicotine aqueous solution that is purified once more with vacuum filtration process.
7, make extraction agent with hydrochloric ether, the nicotine in the nicotine aqueous solution is carried out the extraction second time, the saturated extraction agent of the nicotine that is purified.
8, at negative pressure 400~500mmHg, under the condition that temperature is 60~70 ℃ the saturated extraction agent that contains pure nicotine is carried out multi-effect distilling, obtain the pure nicotine of content more than 98% with molecular sieve dehydration again, be finished product (general international standard).
Method of the present invention can be used for producing in enormous quantities, and its product purity height, color and taste are just, kind is complete, the practical value height, and quality meets international standard, and equipment requirements is not high, and solvent loss is few, and is easy to operate, the extraction yield height.
