Description

    CROSS REFERENCE TO RELATED APPLICATIONS
  • 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
  • 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
  • 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
  • To overcome the disadvantage of the arts, the present invention discloses an application of neophytadiene as an additive for liquid cigarettes.
  • In order to achieve the objects above, in a technology according to the present invention:
  • 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 C20H38, and its structural formula is:
  • Figure US20120211015A1-20120823-C00001
  • Such a liquid cigarette contains atomizing liquid and neophytadiene, specifically, 25˜99.9% weight percent atomizing liquid and 0.01˜75% weight percent neophytadiene. The atomizing liquid contains 60˜95% weight percent propylene glycol, 1˜30% weight percent glycerin, the rest contains flavoring essence, water and ethanol. The 0.01˜20% addition of neophytadiene can generate smell of a cigarette. The 20˜75% addition of neophytadiene can speed up the atomization.
  • Advantages of the present invention include:
  • 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.
  • 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.
  • 3. The 0.01˜20% neophytadiene addition in liquid cigarettes can improve the taste of the inhaled gas or vapor to have a smell of regular cigarettes; 20˜75% neophytadiene addition can speed up the volatilization of the liquid into gas.
  • 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 C20H38.
    • DETAIL EMBODIMENT OF THE INVENTION
  • Neophytadiene can be extracted from tobacco leaves, tobacco stems and wastes, or generated by dehydration of phytol.
  • Specifically, a method for preparing neophytadiene:
  • Figure US20120211015A1-20120823-C00002
    • Chlorophyll
  • 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.
  • Chlorophyll is hydrolyzed under an alkaline condition to generate phytol (C20H39OH):
  • C55H72O5N4Mg+2KOH →CH3OH+C20H39OH+C34H30O5N4MgK2
  • Under the catalytic action and dehydration action of concentrated sulfuric acid, phytol is heated to 170° C., an elimination reaction happens and then generates neophytadiene (C20H38).
  • The generated neophytadiene is used as an additive for liquid cigarettes. It is formed by adding 0.01˜75% neophytadiene into conventional atomizing liquid; the conventional liquid typically contains 60˜95% weight percent propylene glycol, 1˜30% weight percent glycerin, the rest contains flavoring essence, water and ethanol.
  • The liquid cigarette contains atomizing liquid and neophytadiene, specifically, 25˜99.9% weight percent atomizing liquid and 0.01˜75% weight percent neophytadiene.
  • The 0.01˜20% neophytadiene addition in liquid cigarettes can improve the taste of the inhaled gas or vapor to have a smell of regular cigarettes.
  • The 20˜75% neophytadiene addition can speed up the volatilization of the liquid into gas.
    • Embodiment 2
  • Adding 0.01˜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.
  • Adding 20˜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
  • Adding 3˜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.
  • Adding 50˜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.
