Abstract
The present invention relates to a kind of from tobacco the method for extraction nicotine.The nicotine that contains 1-5% in the tobacco, the tobacco leaf of the annual results of tobacco grower, better-than-averagely can directly sell country, discarded tobacco leaf and tobacco rod are often thrown away, and cause waste, the invention is characterized in earlier tobacco leaf, tobacco rod are soaked, extruding obtains leaching liquid, use organic solvent extraction then, use sour backwash at last, obtain nicotine salt.
Description
The present invention relates to a kind of from tobacco the method for extraction nicotine, belong to chemical production field.
At present, tobacco leaf is all planted in a lot of places by China, the tobacco leaf of the annual results of tobacco grower, better-than-average tobacco leaf can directly be sold country, owing to reasons such as technology, weathers, annual also have the discarded tobacco leaf of some amount can not sell and can not burn, again can not as fertilizer sources, the peasant can't slip out of the hand, simultaneously, also have the tobacco rod of some amount, also waste because of can not get reasonable use.
The nicotine that contains 1-5% in tobacco leaf and the tobacco rod, nicotine are a kind of nitrogenous alkaloids, and chemical formula is
The purpose of this invention is to provide a kind of from tobacco the method for extraction nicotine, make these tobacco leaves that go out of use, tobacco rod obtain utilizing, turn waste into wealth.
The present invention is achieved in that and earlier tobacco and water is mixed in certain proportion, makes tobacco soak certain hour in water, pushes tobacco then, and nicotine has just entered immersion liquid like this, then immersion liquid is neutralized with alkali, makes it to be alkalescence.Also contain many impurity because of in the immersion liquid at this moment, so immersion liquid should be filtered, the immersion liquid after the filtration is carried out backwash with acid again, promptly obtains the dilute solution of nicotine salt, and the dilute solution with nicotine salt concentrates at last, promptly obtains the concentrated solution of nicotine salt, just salable finished product.
Accompanying drawing 1 is a process flow sheet of the present invention.
The present invention is described in detail below in conjunction with accompanying drawing:
Among the present invention earlier with tobacco leaf and tobacco rod and water with 1: 2～5(weight ratio) mixed, place and leach the pond, tobacco is soaked more than 24 hours in water, then tobacco is pushed, the liquid of extruding mixes with immersion liquid.
Immersion liquid is taken out, neutralize with alkali, making it pH value is 9～11, preferably makes PH=10, and in this course, the alkali of neutralization usefulness can be Ca(OH)
2, just white lime also can be Mg(OH)
2Immersion liquid after the neutralization can't extract because of containing certain impurity, therefore immersion liquid should be filtered, and during filtration, can adopt vacuum filtration earlier, carries out Plate Filtration again, can obtain clear filtrate through secondary filtration.
Make extraction agent with halogen-containing unsaturated hydrocarbons, extraction agent is fully contacted in extraction tower with clear filtrate, nicotine can be extracted the agent extraction like this, obtains nicotine-containing extraction agent, and used extraction agent can be among the present invention
, also can be
Use this extraction agent, extraction efficiency is more than 70%, and extraction agent still can be recycled after with sour backwash.
The extraction agent that will contain nicotine arrives PH=2～4 with sour backwash, and as PH＞4, then backwash efficiency is low, causes waste, and when PH＜2, it is big, nonconforming to concentrate back product acid content, preferably make PH=3, so just can obtain the dilute solution of nicotine salt, just work in-process.The acid that backwash is used can be dilute sulphuric acid, also can be dilute hydrochloric acid, gets nicotine sulfate salt with the dilute sulphuric acid backwash, obtains nicotine hydrochloride salt with the dilute hydrochloric acid backwash.Efficient with sour backwash can reach more than 90%.
The nicotine salt dilute solution that obtains with the diluted acid backwash can't be sold because of too rare, it should be concentrated the concentrated solution that obtains nicotine salt, be finished product.
This from tobacco the method for extraction nicotine, raw materials used wide material sources, and technology is simple, equipment requirement is not high, has economic and practical.
