Abstract
The invention discloses a preparation method of an electronic cigarette juice. The preparation method is characterized by comprising the following steps of using an organic solvent to extract tobacco water or alcohol extract, collecting organic phase, removing the organic solvent by distilling, preparing a tobacco extract, dissolving the extract by a mixture solvent of ethanol, propylene glycol and glycerol according to certain proportion, removing undissolved substances, and obtaining supernatant liquid, namely the electronic cigarette juice. The preparation method has the characteristic that the ethanol and the water extraction solution of tobacco are subject to reextraction by the solvent which does not dissolve sugar, extraction phase completely not containing sugar is obtained, and the electronic cigarette juice is prepared, so as to well solve the problems that electronic cigarette juice of the prior art has high sugar content and is easily converted into harmful carbonyl compounds, such as formaldehyde, after being heated.
Description
Technical field
The present invention relates to a kind of preparation method of tobacco juice for electronic smoke, belong to tobacco chemical field.
Background technology
Electronic cigarette has another name called virtual cigarette, primarily of holding the cigarette bullet of nicotine solution, atomizer and lithium battery three part composition.Atomizer is battery-powered, the liquid nicotine in cigarette bullet can be transformed into fog, thus allows user have a kind of sensation of similar smoking when inhaling.
The main component of electronic cigarette liquid is propane diols, glycerine and extract from tobacco cause perfumery, then be equipped with essence, the spices of the various tastes such as such as chocolate, peppermint is in order to meet the hobby of consumer.Wherein the overwhelming majority utilizes to cause perfumery in water and alcohol extract tobacco.It is reported, some medicinal herb componentses can also be added wherein, play certain health care etc.Also having some to get around control, directly dissolving all kinds of essence with glycerine, propane diols and making, completely not containing nicotine composition.
The patent report of existing many related electronic cigarette tobacco juices at present, such as 1. CN103622154A electronic cigarette liquid and preparation method thereof, 2. the tobacco juice of CN103610229A electronic cigarette, 3. the preparation method of a CN102349699B electronic cigarette liquid, 4. CN102960852A simple and elegant odor type electronic cigarette atomizing tobacco juice and preparation method thereof, 5. CN103054172A tobacco juice for electronic smoke utilizing strong-flavor tobacco leaf to prepare, 6. the CN103070473A mono-kind tobacco juice for electronic smoke that utilizes delicate fragrance type tobacco leaf to prepare, 7. CN103070472A mono-kind effectively improves the tobacco juice for electronic smoke of electronic cigarette aesthetic quality, 8. CN103054173A tobacco juice for electronic smoke etc. utilizing discarded tobacco leaf to prepare.But it is that tobacco extract by ethanol, ethylene glycol and water is prepared from that these tobacco juices have, and also has and uses essence and flavoring agent and glycerine, propane diols to blend the tobacco juice formed described in invention completely.Use polar solvent when such as ethanol, ethylene glycol and water extract tobacco, in extract, the content of sugar is often higher, and time particularly using Virginia tobacco as extraction raw material, sugar content is higher.For hot type electronic cigarette, these sugars, when being heated, easily transform into harmful carbonyls such as formaldehyde.
Summary of the invention
Object of the present invention provides a kind of preparation method of tobacco juice for electronic smoke just based on above-mentioned current condition, strip with the ethanol of solvent to tobacco, the aqueous extract that do not dissolve sugar, obtain completely not sugary extraction phase, make tobacco juice for electronic smoke with this, well solve the deficiencies in the prior art.
The object of the invention is to be achieved through the following technical solutions: a kind of preparation method of tobacco juice for electronic smoke, comprises following concrete steps:
(1) extract: adopt the mode of soaking, stir or refluxing to extract tobacco leaf or offal, Extracting temperature is room temperature-70 degrees Celsius, and extraction time is 0.5-48h;
(2) remove the ethanol in extract: the mode adopting decompression distillation, by the ethanol removing in extract, if adopt water as Extraction solvent, then do not need this process;
(3) extract: with the solvent of certain volume, extract is extracted, water phase separated and organic phase, the ratio of solvent for use and extract is 0.5-10:1, and described solvent comprises cyclohexane, carrene, benzinum, ethyl acetate, dichloroethanes, or the mixture of these solvents;
(4) solvent is removed: the mode adopting decompression distillation, by the solvent in organic phase and micro-moisture evaporate to dryness, obtained tobacco extract medicinal extract;
(5) dissolve medicinal extract with a certain proportion of ethanol, propane diols, glycerine mixed solvent, the clarified solution obtained after removing insoluble matter is tobacco juice for electronic smoke of the present invention.This is because medicinal extract solubility is in ethanol greater than its solubility in propane diols, glycerine, and ethanol is as the solvent of tobacco juice for electronic smoke, but aesthetic quality is not as propane diols and glycerine, therefore, dissolve with a certain proportion of mixed solvent, ethanol can play the effect of hydrotropy medicinal extract on the one hand, has taken into account again the impact of solvent on tobacco juice for electronic smoke aesthetic quality on the other hand.
In the present invention, described Extraction solvent is water, ethanol or ethanol water, and ethanol water concentration range is 5%-95%
.solid-liquid ratio in leaching process is 1: 5-20.
The ratio of the ethanol described in step (5), propane diols, glycerine mixed solvent is 1: 9-0: 0-9, and namely when ethanol 1 part, propane diols, glycerine add up to 9 parts.
Feature of the present invention is: propose to strip with the ethanol of solvent to tobacco not dissolving sugar, aqueous extract, obtain completely not sugary extraction phase, make tobacco juice for electronic smoke with this, well solve electronic cigarette liquid sugar content in prior art high, be heated after be easily converted into formaldehyde etc.
