A Kind of Preparation Method of E-Cigarette Liquid
Field of Technology
This invention relates to a kind of preparation method of E-cigarette liquid
which
belongs to the field of chemical preparing technology.
Background Technology
E-cigarette liquid (or E-cigarette atomizing liquid) is the popular cigarette
substitute product currently. Concerning the mixing prescription, preparation
process,
health caring function and other aspects of E-cigarette liquid, there has been
many
documentary or patented reports. Mixed by 25-90 proportions of polyethylene
glycol,
9-50 proportions of propylene glycol and 0.3-52 proportions of taste
regulator, a kind of
electronic simulation cigarette atomizing liquid disclosed by Chinese patent
200910104922.6 belongs to typical essence and spice mixing products. Mixed by
3-5%w/v of tobacco extractive, 3-5% w/v of tobacco spice, 0-3% w/v of
nicotine,
0.2-1% w/v of stabilizing agent, 3-8% w/v of thickener, 5-10% w/v of pure
water,
50-70% w/v of propylene glycol and other elements like codeine phosphate,
chlortrimeton etc., though it uses tobacco extractive, the electronic
cigarette atomizing
liquid disclosed by Chinese patent 200910310536.2 is still the product that
imitates
cigarette taste and mixes by tobacco extractive as well as other spices. Due
to the
reason that more and more smokers begin to adopt E-cigarette to replace
cigarette,
some shortcomings of the electronic cigarette liquid used in these E-
cigarettes become
more obvious. It is generally reflected by smokers that although E-cigarettes
have the
similar appearance, feeling and smog like those of cigarettes, there is a
rather wide gap
between them in the aspects of aroma and taste, especially the products mixed
by
various essence and spices that make smokers feel hard to accept or get used
to. In
addition, it is also the general problem of users that it is difficult for
current aroma
elements of E-cigarette liquid to retain for a long time that the best ones
can only be
kept for about half a year during which the "smell of cigarette" will become
thin or just
disappear. Those shortcomings influence the quality of E-cigarette to a great
extent and
restrict the popularity and prevalence of E-cigarette meanwhile.

Contents of Invention
Aiming at the shortcomings like bad aroma and taste, short time for keeping
the
essence etc. existing in the E-cigarettes, the purpose of this invention is to
provide a
kind of preparation method of E-cigarette liquid. Letting the natural aroma
elements
of tobacco enter the E-cigarette liquid, this method makes the aroma and taste
come
from the tobacco and be closer to those of cigarettes, which can cater to the
smoking
feeling of customers and makes the time much longer for keeping the natural
aroma in
cigarette liquid.
This Invention Will Be Implemented According to the Technical Proposals Below
Certain amount of E-cigarette liquid should be prepared according to the plan.
First, get the tobacco (weight) with 5-20% (w/v) of E-cigarette liquid amount
(volume)
and put into the extracting tank. Then add the mixed solvent into the tank and
soak the
tobacco for 30-100 minutes. After heating it up to 40-601C and extract with
warm soak
for 2-8 hours, filter the extract and get the filtrate. Then add chocolate
extract with the
amount of 1-10% (w/v) of the E-cigarette liquid into the filtrate and stir the
mixture for
20-40 minutes. After that, complement the E-cigarette liquid volume of 100%
planning
preparation with propylene glycol or polyethylene glycol and stir them until
mix
uniformly to finish the product.
The preparation of the solvent above is to respectively get the propylene
glycol
and/or polyethylene glycol with the amount of 30-80% of the E-cigarette liquid
volume
and 0.1-0.5% of tween 80, and then stir them for 20-40 minutes to get the
uniformly
mixed solvent;
The preparation of chocolate extractive above includes the following steps.
Smash
the chocolate to 20-60 sections and put into the extracting tank with
interlayer, add
distilled water of which the weight is 3-10 times of the chocolate powder,
soak the
powder for 30-90 minutes and heat it up to 80-901C, extract with heat
preservation for
2-6 hours, pour out and filter the extract and keep the residue for other
functions, then
decompress and concentrate the extract to the extract with the proportion of
1.1-1.4 to
get the chocolate extractive;
The propylene glycol or polyethylene glycol solvent and tween 80 above are all
with
the officinal or edible level, among which propylene glycol and polyethylene
glycol can

be used solely as well as in combination.
Advantages and Positive Effect Compared with Public Technology
There are two reasons for using propylene glycol or polyethylene glycol
solvent with
tween 80 as the extract and directly extracting tobacco in comparatively mild
conditions. First, the aroma elements of tobacco can directly enter the
extract. Second,
extracting tobacco in mild conditions can avoid the loss and damage of some
tobacco
aroma elements that are easily-volatilized or sensitive to temperature under
the
conditions of complex process and high-temperature concentration. In addition,
comparing with other common solvent that extracts aroma elements, propylene
glycol
or polyethylene glycol solvent can better keep the aroma due to their high
viscosity and
certain moisturizing function. After used by a large number of customers, this
product
is commonly preferred by them because the taste is close to the cigarette and
the aroma
can be well kept even when the product is kept for two to three years.
Specific Ways of Implementation
Case 1: Plan to prepare 500 liters of E-cigarette liquid. Get 50 kilograms of
tobacco and put into the extracting tank with interlayer; respectively get 350
liters of
propylene glycol and 1 liter of tween 80, then pour the latter into the former
and stir
the mixture for 30 minutes. Add the mixed liquor into the extracting tank and
soak the
tobacco for 50 minutes. Then use steam to heat it up to 501C through the
interlayer.
After extracting with heat preservation for 4 hours, pour out the extract and
filter it to
get the filtrate. Add 18 kilograms of chocolate extractive into the filtrate
and stir the
mixture for 30 minutes. Then add 500 liters of propylene glycol into the
filtrate to
complement the planning preparation and stir the mixture for 35 minutes to get
the
E-cigarette liquid.
Case 2: Plan to prepare 500 liters of E-cigarette liquid. Get 50 kilograms of
tobacco and put into the extracting tank with interlayer; get and mix 380
liters of
propylene glycol and polyethylene glycol according to the proportion of 1:1,
and get 1.5
liters of tween 80. Pour the tween 80 into the mixture of propylene glycol and
polyethylene glycol and stir it for 40 minutes and then add it to the
extracting tank and
soak the tobacco for 60 minutes. Use steam to heat it up to 60'C through the
interlayer.
After extracting with heat preservation for 6 hours, pour out the extract and
filter it to

get the filtrate. Add 20 kilograms of chocolate extractive into the filtrate
and stir the
mixture for 40 minutes. Then add 500 liters of polyethylene glycol into the
filtrate and
stir the mixture for 30 minutes to get the E-cigarette liquid.
