A kind of cigarette preparation method of latent 2,3 diformic ester of perfume monomer pyrazine, comprises the steps：Take pyrazine 2,3 dioctyl phthalate and single hydroxyl alcohol are dissolved in dry dichloromethane, stir 10min 30min, add 4 dimethylamino naphthyridines (DMAP) and 1 ethyl (3 dimethylaminopropyl) phosphinylidyne diimmonium salt hydrochlorate (EDCHCl), 4 12h are stirred at room temperature, TLC monitoring reactions, track reaction end, and add water in organic faciess washing, divide liquid, washed with saturated nacl aqueous solution again, point liquid, organic faciess anhydrous Na2SO4Dry, be concentrated to give crude product, then carry out column chromatography for separation and obtain final product the product.Product prepared by the present invention can significantly improve the addition in Medicated cigarette, and not affect the outer fragrant kind of Medicated cigarette, be applied in Medicated cigarette as fragrance-enhancing tobacco agent, it is possible to decrease the zest of Medicated cigarette and miscellaneous QI, improve the mellow and full sense of cigarette smoke and comfortableness.
Description
Technical field
The present invention relates to essence and flavoring agent and tobacco manufacture field, specifically a kind of cigarette latent perfume monomer pyrazine -2,3- diformazans
The preparation method and applications of esters of gallic acid.
Background technology
Many excellent spice are as its high high-temp stability is poor, volatility compared with strong, fragrance remaining time is short the problems such as limit
Which is widely applied.Latent Studies of The Aromatic Substances is that a class relative molecular mass is big, the material that boiling point is higher, and fragrance is less or does not have perfume (or spice) in itself
Gas, but can discharge with fragrance fragrance through the approach such as chemical hydrolysis, enzymolysis or microbial action, pyrolysis, photodestruciton
Compound.Because of its safety preferably, listed in natural perfume material category in the world, allocated some local flavor edible essence effects with which
Very well.Different from volatility and half volatile fragrance matter, perfume class compound of diving is reducing artificial flavor and taste compensation vestige
It is not result in the significant changes of the material delivering amount such as nicotine in cigarette mainstream flue gas, tar simultaneously, more longlasting can stably provides cigarette
Gas characteristic chicken flavor.In prior art, latent Studies of The Aromatic Substances is widely applied in the adding technology of cigarette shreds, and the present invention provides one
Cigarette latent perfume monomer pyrazine -2, the preparation method of 3- diformic esters is planted, and inquires into its application in perfuming cigarette.
Content of the invention
The present invention is in order to develop new cigarette flavor precursors, there is provided a kind of cigarette latent perfume monomer pyrazine -2,3- dioctyl phthalate
The preparation method and applications of esters.
For achieving the above object, the present invention is adopted the following technical scheme that：
A kind of cigarette latent perfume monomer pyrazine -2, the preparation method of 3- diformic esters, which comprises the steps：
Pyrazine -2 are taken, 3- dioctyl phthalate and single hydroxyl alcohol are dissolved in dry dichloromethane, stir 10min-30min, added
DMAP (DMAP) and 1- ethyls-(3- dimethylaminopropyls) phosphinylidyne diimmonium salt hydrochlorate (EDCHCl), room temperature
Stirring 4-12h, TLC monitoring reaction (petroleum ether：Ethyl acetate=10:1, Rf=0.5, ultraviolet 254nm colour developings), tracking reaction is eventually
Point, add water in organic faciess washing, point liquid, then is washed with saturated nacl aqueous solution, point liquid, organic faciess anhydrous Na2SO4Dry,
Crude product is concentrated to give, column chromatography for separation is then carried out and is obtained final product the cigarette latent perfume monomer pyrazine -2,3- diformic esters.
Further, described column chromatography for separation eluent is ethyl acetate and petroleum ether, both volume ratios 100:1-
20:1.
Further, described pyrazine -2, the molar ratio of 3- dioctyl phthalate and single hydroxyl alcohol is 0.9:1-1:Between 0.9.
Further, described single hydroxyl alcohol is geraniol or ionol, when single hydroxyl alcohol is geraniol, obtains
Product be pyrazine -2, two Herba Pelargonii Graveolentiss alcohol ester of 3- dioctyl phthalate, when single hydroxyl alcohol be ionol when, the product for obtaining be pyrazine -2,3-
Two-β of dioctyl phthalate-ionol esters, both structural formulas are as follows：
Further, the cigarette that prepared by method as defined above is increased as Nicotiana tabacum L. with latent perfume monomer pyrazine -2,3- diformic esters
Application of the pastil in Medicated cigarette, is applied in Medicated cigarette as fragrance-enhancing tobacco agent, 0.01- of the addition for tobacco shred weight
0.05%.
Two Herba Pelargonii Graveolentiss alcohol ester of the compounds of this invention pyrazine -2,3- dioctyl phthalate and two-β of pyrazine -2,3- dioctyl phthalate-ionol esters
For a kind of latent aroma compounds, under room temperature, which is stable in properties, is yellow liquid, but which passes through to heat cleavable and produce that there is substantially increasing
Plus tobacco aroma material, such as 3- oxo-beta-ionones, pyrazine, geraniol, monoterpene vinyl compound.
Compared to the prior art, beneficial effects of the present invention：
1. the present invention prepares two Herba Pelargonii Graveolentiss alcohol ester of pyrazine -2,3- dioctyl phthalate and pyrazine -2,3- dioctyl phthalate two-β-ionol esters
Compared with geraniol and β-ionol parent thing, the addition in Medicated cigarette can be significantly improved, and does not affect the outer perfume (or spice) of Medicated cigarette
Kind.
2. the present invention with DMAP/1- ethyls-(3- dimethylaminopropyls) phosphinylidyne diimmonium salt hydrochlorate is
Pyrazine -2,3- dioctyl phthalate and geraniol, β-ionol esterification reaction condensation reagent, can significantly improve reaction yield, simplify
Aftertreatment technology.
3. two kinds of cigarette monomer perfumes that the present invention is developed, are applied in Medicated cigarette as fragrance-enhancing tobacco agent first,
Zest and the miscellaneous QI of Medicated cigarette can be reduced, the mellow and full sense of cigarette smoke and comfortableness is improved.
