Description
Technical field
The present invention relates to a kind of electronic cigarette liquid, belong to electronic cigarette field.
Background technology
Along with the raising of people's living standard, smoking and health problem become the focus of social concerns.Under this background, the research of the novel tobacco product such as low temperature cigarette, electronic cigarette more and more receives publicity.
Electronic cigarette belongs to the one of novel tobacco goods, and its basic technique principle is, when sucking electronic cigarette, electronic cigarette battery is powered to electronic smoke atomizer, and atomizer is started working, and the tobacco juice atomization be stored in electronic cigarette is produced smog.Tobacco juice in electronic cigarette, also claims " tobacco tar ", is stored in sorbing material, is commonly called as " adsorption cotton ".Tobacco juice in electronic cigarette, is actually a formula essence, and when sucking electronic cigarette, atomization is " smog ", and smog comprises the material such as glycerine, propane diols evaporated in essence and the fragrance matter evaporated in essence.
The composition of electronic cigarette liquid can be roughly divided into two parts, and a part causes perfumery; A part is base solvent, causes perfumery for dissolving.Solvent can be water, and also can be glycerine, some organic solvents of propane diols, part organic solvent self also has certain fragrance.Conventional base solvent is one or more in glycerine, propane diols, ethanol, and wherein solvent can also add water increases the polarity of solvent to increase the dissolubility of polarity aroma component.
The form of burning with cigarette with traditional cigarette provides compared with sense organ meets to smoker, and electronic cigarette is to the sensory evaluation of smoker, and tobacco flavor is thin often, lacks the peculiar burnt odor that burning tobacco brings.
Chinese patent CN 104026729 A discloses a kind of electronic cigarette liquid with burnt odor fragrance, and it utilizes white granulated sugar or brown sugar to be raw material, carries out caramelization at a certain temperature, obtain the product with burnt odor fragrance with offal, pipe tobacco or cigarette ash.This product is divided into two parts, and a part causes perfumery, and namely pipe tobacco or offal are warming up to the product after 180-250 DEG C of reflux heating 10-20 min; Another part is base solvent, i.e. the glycerine of 10-50 mL, the mixed solvent of second alcohol and water.But this tobacco juice baking perfume (or spice) is denseer, and mouthfeel is pure not.
Summary of the invention
The present invention is the above-mentioned technical problem solved, and provide a kind of preparation method of burnt odor electronic cigarette liquid to overcome electronic cigarette liquid baking perfume (or spice) in prior art denseer, the defect that mouthfeel is pure not, makes the fragrance of electronic cigarette closer to traditional cigarette.
Technical scheme of the present invention is, provides a kind of electronic cigarette liquid, comprises base solvent and cause perfumery, described in cause perfumery with pipe tobacco or offal for raw material, temperature be 150 ~ 250 DEG C, pressure be the condition of 2 ~ 10 mmHg under decompression distillation obtain.
Further, causing the concentration of perfumery in base solvent described in is 0.01 ~ 0.2 g/ml.
Further, described temperature preferably 180 ~ 200 DEG C.
Further, described electronic cigarette liquid also comprises auxiliary material.
Another technical scheme of the present invention provides a kind of electronic cigarette, employs above-mentioned electronic cigarette liquid.
Described auxiliary material in description can be described in cause in perfumery one or more, increase auxiliary material to make certain smell in tobacco juice more outstanding, be applicable to dissimilar consumer.In addition, auxiliary material also can be other conventional additives.
The present invention burns and sucks mechanism by dissecting cigarette, design heating preparation experiment, and the pyrolytical condition of simulated combustion cigarette, preparation also effectively collects aroma component, is made into electronic cigarette liquid and is applied to electronic cigarette.
In order to better simulate the pyrolytical condition of result of combustion of tobacco, the mechanism discharging fragrance matter when being necessary to burn to traditional cigarette dissects: different with chemical reaction according to its variations in temperature during cigarette burning, three different regions can be divided into, i.e. high temperature combustion zone A, pyrolysis distillation zone B and low temperature cold coagulation zone C.Wherein the temperature of high temperature combustion zone is higher, is about 600 ~ 900 DEG C, and the product mainly gaseous substance of generation, as lower hydrocarbon compounds and some free radicals such as carbon dioxide, carbon monoxide, water, hydrogen, methane.The product in this district is little to the contribution of flue gas aroma component, is mainly pyrolysis distillation zone B and provides thermal source.Be pyrolysis distillation zone B after combustion cone, the feature in this district is the pyrolysis distillation zone oxygen supply deficiency at combustion cone center, and reaction is carried out under anaerobic condition.Thermal current from high temperature combustion zone provides thermal source, result in the complicated chemical change of pyrolysis distillation zone.Many materials in pipe tobacco carry out violent complicated chemical reaction at this, as reactions such as thermal decomposition, thermal synthesis, destructive distillation, polymerization, condensation, free radicals, most compounds in flue gas are all here formed, and aroma component important in obvious flue gas also produces in pyrolysis distillation B district.Condensation filtering area C is called from pyrolysis distillation zone to the end of cigarette.At this, the temperature of flue gas is down to room temperature by 100 DEG C.
From traditional cigarette combustion mechanism, most aroma component all produces in pyrolysis distillation B district, and the feature in this district is that oxygen supply is not enough, and reaction under anaerobic conditions produces; The temperature in pyrolysis distillation B district is lower than high-temperature region in addition, there are some researches show that reaching 300 DEG C can be evaporated the volatility aroma component in pipe tobacco.
In view of the aroma component overwhelming majority in flue gas derives from pyrolysis distillation B district, and the distinguishing feature in pyrolysis distillation B district is: one is anoxic, and two is need to reach the thermal source of 300 DEG C.The present invention designs Heating Experiment, manufactures anaerobic environment by decompression, by producing fragrant mode lower than 300 DEG C of heating decompressions, realizes the preparation to aroma component in tobacco, and the object of decompression has be manufacture anaerobic environment at two: one, and two is the temperature reducing evaporative distillation.Concerning same compound, pressure is less, and boiling point is lower, is more easily evaporated.
The present invention finds through repeated multiple times experiment, and when reducing pressure to 10 mmHg, fragrant temperature 150 ~ 250 DEG C is produced in heating, can obtain the aroma substance of similar burning cigarette.Temperature is too low, and the aroma component burnt odor obtained is inadequate; Temperature is too high, and sootiness gas is overweight, has heavier to be charred taste.Temperature is at 180 ~ 200 DEG C, and sensory evaluating smoking's evaluation effect is best.
During evaporative distillation, the volatility aroma component cooling steamed can better also farthest be collected by the use of circulating cooling liquid.The temperature range of circulating cooling liquid is-10 ~-5 DEG C.
The present invention and aerobic produce fragrant difference and are: (1) the present invention is by reducing pressure the most air extracted out and produce in fragrant system, be less than the environment of 10 mmHg at pressure under, namely carry out the cracking release under uniform temperature and evaporation under anaerobic environment, this environment is more close to the pyrolysis distillation B district of burning cigarette.On the other hand, the boiling point of reduced pressure atmosphere flavor matter can reduce, and lower more than the 250 DEG C flavor matters that just can be evaporated of such as normal pressure, when vacuum reaches 10 mmHg or is lower, can be evaporated at about 180 DEG C.Can learn according to boiling point conversion chart, when vacuum reaches 10 mmHg, under normal pressure, boiling point is that the boiling point of the compound of 300 DEG C is reduced to 155 DEG C; When vacuum reaches 2 mmHg, under normal pressure, boiling point is that the boiling point of the compound of 300 DEG C is reduced to 120 DEG C.From above data, the present invention is reduced pressure 10 mmHg or lower, and the flavor matter in pipe tobacco or offal is more easily evaporated, and it is obviously higher to produce fragrant efficiency.(2) the flavor matter composition of contrast aerobic cracking and anaerobic cracking of the present invention (or cracking under anaerobic environment) is analyzed, can to learn under anaerobic environment of the present invention in pyrolysis product, Furanones spices is (as 2,4-dihydroxy-2,5-dimethyl-3(2H)-furans-3-ketone, DDMP etc.) content significantly increase, and containing more high-quality spices Megastigmatrienone in the fragrant product of product of the present invention; In addition, the fragrant product of product of the present invention contains more nitrogen-containing compound, and as pyridines and class nicotine, this kind of substance significantly increases the satisfaction of electronic cigarette.(3) sensory evaluating smoking evaluates and shows, produce the fragrant tobacco juice obtained under hypobaric hypoxia environment of the present invention, mouthfeel is purer, and assorted gas is few, increases electronic cigarette satisfaction, the fragrant feature of the cigarette closer to traditional combustion type cigarette.
Cause the concentration of perfumery in base solvent in the present invention and be preferably 0.01 ~ 0.2 g/ml, cause perfumery concentration very weak lower than the cigarette perfume (or spice) of the electronic cigarette liquid of 0.01 g/ml, cause perfumery to be too much difficult to directly absorb completely by base solvent, fragrance overrich may be caused simultaneously and need suitably to add base solvent dilution.
In sum, the present invention manufactures anaerobic environment by decompression distillation, and collects cut under the condition of 150-250 DEG C, 2-10 mmHg, obtains the electronic cigarette liquid with burnt odor taste, and this kind of electronic cigarette liquid burnt odor taste is pure, and mouthfeel is pure, and pleasant impression is clean.
