Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation of International
Application No. PCT/CN2010/073621, filed Jun. 7, 2010 and
designating the U.S., which claims priority to Chinese Patent
Application No. 200910012125.5, filed Jun. 19, 2009, both of which
are incorporated herein by reference in their entirety.
TECHNICAL FIELD
[0002] The present invention relates to evaporation in liquid
cigarettes or additive for atomizing cigarettes, and particularly
to applications of neophytadiene as an additive for liquid
cigarettes.
BACKGROUND
[0003] Presently, two kinds of sucking devices are known as
cigarette substitutes and being useful for smoking cessation. One
of them includes a porous body having a relatively large surface
area retaining a liquid mixture of various components, which has a
smell of cigarette. When inhaled air flows through the porous body,
a good deal of liquid is vaporized and mixed with the air so as to
provide satisfaction to the smoker; the other kind of sucking
device places the liquid in an atomizing electronic cigarette,
which vaporizes the liquid by an atomizer and provide the generated
vapor to the user, so as to simulate functions of a regular
cigarette. However, an important disadvantage of such devices is
that they cannot simulate the taste and smell of regular
cigarettes.
SUMMARY OF THE INVENTION
[0004] To overcome the disadvantage of the arts, the present
invention discloses an application of neophytadiene as an additive
for liquid cigarettes.
[0005] In order to achieve the objects above, in a technology
according to the present invention:
[0006] Neophytadiene is used as an additive for liquid cigarettes.
Neophytadiene is a diterpenoid compound and is liquid at room
temperature. The molecular weight of the neophytadiene is 278.52,
its molecular formula is C.sub.20H.sub.38, and its structural
formula is:
##STR00001##
[0007] Such a liquid cigarette contains atomizing liquid and
neophytadiene, specifically, 25.about.99.9% weight percent
atomizing liquid and 0.01.about.75% weight percent neophytadiene.
The atomizing liquid contains 60.about.95% weight percent propylene
glycol, 1.about.30% weight percent glycerin, the rest contains
flavoring essence, water and ethanol. The 0.01.about.20% addition
of neophytadiene can generate smell of a cigarette. The
20.about.75% addition of neophytadiene can speed up the
atomization.
[0008] Advantages of the present invention include:
[0009] 1. In the present invention, neophytadiene is used as an
additive for liquid cigarettes, so as to improve the taste of the
inhaled gas or vapor, to make them have a smell of a regular
cigarette.
[0010] 2. In the present invention, the addition of neophytadiene
facilitates the transformation of the liquid into gas, especially
the vaporization in a liquid cigarette, by speeding up the
atomization, so as to save electric power for batteries.
[0011] 3. The 0.01.about.20% neophytadiene addition in liquid
cigarettes can improve the taste of the inhaled gas or vapor to
have a smell of regular cigarettes; 20.about.75% neophytadiene
addition can speed up the volatilization of the liquid into
gas.
[0012] Neophytadiene exists widely in tobaccos, and is one of the
components of cigarette combustion smoke. Neophytadiene is almost
odorless and has a smell of cerolipoid which is adverse to the
smell of the smoke. Neophytadiene is a diterpenoid compound and is
liquid at room temperature. The molecular weight of the
neophytadiene is 278.52, and its molecular formula is
C.sub.20H.sub.38.
DETAIL EMBODIMENT OF THE INVENTION
[0013] Neophytadiene can be extracted from tobacco leaves, tobacco
stems and wastes, or generated by dehydration of phytol.
[0014] Specifically, a method for preparing neophytadiene:
##STR00002##
Chlorophyll
[0015] A Chlorophyll molecule comprises two parts, a polar
porphyrin head (N has a part of negative charges, Mg has a part of
positive charges) and an apolar phytol tail.
[0016] Chlorophyll is hydrolyzed under an alkaline condition to
generate phytol (C.sub.20H.sub.39OH):
[0017] C.sub.55H.sub.72O.sub.5N.sub.4Mg+2KOH
.fwdarw.CH.sub.3OH+C.sub.20H.sub.39OH+C.sub.34H.sub.30O.sub.5N.sub.4MgK.s-
ub.2
[0018] Under the catalytic action and dehydration action of
concentrated sulfuric acid, phytol is heated to 170.degree. C., an
elimination reaction happens and then generates neophytadiene
(C.sub.20H.sub.38).
[0019] The generated neophytadiene is used as an additive for
liquid cigarettes. It is formed by adding 0.01.about.75%
neophytadiene into conventional atomizing liquid; the conventional
liquid typically contains 60.about.95% weight percent propylene
glycol, 1.about.30% weight percent glycerin, the rest contains
flavoring essence, water and ethanol.
[0020] The liquid cigarette contains atomizing liquid and
neophytadiene, specifically, 25.about.99.9% weight percent
atomizing liquid and 0.01.about.75% weight percent
neophytadiene.
[0021] The 0.01.about.20% neophytadiene addition in liquid
cigarettes can improve the taste of the inhaled gas or vapor to
have a smell of regular cigarettes.
[0022] The 20.about.75% neophytadiene addition can speed up the
volatilization of the liquid into gas.
Embodiment 2
[0023] Adding 0.01.about.3% weight percent neophytadiene into
conventional atomizing liquid as a liquid cigarette additive can
generate smell of cigarettes, and improve the taste of inhaled gas
or vapor, so as to provide it with smell of regular cigarettes.
[0024] Adding 20.about.75% weight percent neophytadiene into
conventional atomizing liquid as a liquid cigarette additive can
speed up the vaporization of the liquid, increase the speed of the
liquid's volatilization to become gas.
Embodiment 3
[0025] Adding 3.about.10% weight percent neophytadiene into
conventional atomizing liquid as a liquid cigarette additive can
generate smell of cigarettes, and improve the taste of inhaled gas
or vapor, so as to provide it with smell of regular cigarettes.
[0026] Adding 50.about.70% weight percent neophytadiene into
conventional atomizing liquid as a liquid cigarette additive can
speed up the vaporization of the liquid, increase the speed of the
liquid's volatilization to become gas.
