Description
Technical field
The present invention relates to the methods that nicotine tar is extracted from tobacco leaf, belong to agricultural machining technical field.
Background technique
Coal tar is one of the product in the raw gas that coking industry pyrolysis of coal generates, yield account for about furnace coal 3% ~
4% its composition is extremely complex, is used after exclusively carrying out separation, purification by coal-tar industry in most cases.It is normal in room temperature
Its product is depressed in black viscous liquid, each fraction further processing may separate out multiple product, such as camphor ball, pitch, modeling
Material, pesticide etc..
The main component of wood tar is wood creosote, and usually the tar made from the non-resin-soaked wood is distilled, uses hydrogen
Sodium oxide molybdena processing, be acidified again and redistillation be allowed to after being separated with other compositions be made.Wood creosote is colourless liquid, but in air
With color is presented under the action of light, have smoke, be corrosive, be mainly used as disinfectant and preservative.
The main component of wood tar is wood creosote, and usually the tar made from the non-resin-soaked wood is distilled, uses hydrogen
Sodium oxide molybdena processing, be acidified again and redistillation be allowed to after being separated with other compositions be made.Wood creosote is colourless liquid, but in air
With color is presented under the action of light, have smoke, be corrosive, be mainly used as disinfectant and preservative.
Wood tar is a kind of hydrocarbon-containifirst, acids, the higher organic compound of phenols, can get creasote, anti-poly- after processing
Agent, floatation frother, the products such as wood pitch.It can also be used for the departments such as medicine, synthetic rubber and metallurgy.
Wood tar: the product ejected when carbonizing in charcoal kiln for timber (needlebush or other wood) is (for example, Sweden's tar
Or pine tar) or distillation product obtained (the distillation tar) in retort or retort.Distilling tar can be directly from Jiao Mushui
It precipitates and obtains (insoluble tar), (dissolved tar) can also be made by retort coke wood water (tar has been partly dissolved).
All these tar are all the complex mixtures of hydrocarbon, phenol and its homologue, alditol, acetic acid and other various products.
The tar made from the resin-soaked wood with contain resin distillage (terpenes, retinal made from the non-resin-soaked wood
Deng) tar it is different, it is viscous product, and color is from pale brown to dark brown different.Through simple dehydration or part distill it is resulting this
A little products are mainly used for dipping cable for ship, the plasticizer as rubber industry, for filleting glue processed and for medicine etc..
The tar made from the non-resin-soaked wood is the thick liquid of brownish black, can be made each after distillation or other methods processing
The byproduct (the wooden heteroacid oil, guaiacol etc.) of formula various kinds.
(2) wood tar is refined, is obtained by distillation wood tar.Light oil (containing aliphatic hydrocarbon, terpenes and higher ketone) therein
For sheep liquid for medicinal bath processed and gardening spray, and heavy oil (containing aliphatic hydrocarbon and aromatic hydrocarbon, higher ketone and higher phenols) is for impregnating
Timber and extraction wood creosote.
Resulting removing impurities carbolic oil can be used for floatation beneficiated ore, insecticide processed and use according to its characteristic after extraction creasote
Make solvent and fuel etc..
(3) wood creosote is the main component of wood tar, and usually the tar made from the non-resin-soaked wood is distilled,
With naoh treatment, again be acidified and redistillation be allowed to after being separated with other compositions be made.Wood creosote is colourless liquid, but
Color is presented under the action of air and light, has smoke, is corrosive, be mainly used as disinfectant and preservative.But it is sure not and creosote
Oil or mineral creasote are mutually obscured, and creasote or mineral creasote are included into duty paragraph 27.07.
Two, crude wood naphtha is obtained by the burnt wooden water of processing.It is a kind of light yellow liquid, there is an empyreumatic taste, usually containing 70~
90% methanol and the acetone of different proportion and other ketone (usual 8~20%), also containing other impurities (methyl acetate, higher alcohol,
Tarry matters etc.).Certain crude wood naphthas are used as Denaturant for ethanol.
Summary of the invention
In order to overcome conventional method to extract the method disadvantage of tar, a kind of nicotine tar of my invention extracts preparation skill
Art, this method do not have to heating, and process is simple, and oil yield is high, and large-scale production is suitble to extract the processing of eucalyptus oil.
A kind of nicotine tar extracts technology of preparing and solves the problems, such as to adopt the technical scheme that be carried out by following step:
One, raw material: dry tobacco leaf；Main tool: high-power bruisher, large-scale squeezer, conveyer belt machine, centrifuge, filter screen, extraction
Take cylinder；Two, it smashs program to pieces: dry tobacco leaf is smashed into pieces diameter≤0.3cm clast or fine item with high-power bruisher, with biography
The tobacco leaf for the drying smashed to pieces is directly transmitted to large-scale squeezer by ribbon feeder；Three, level-one mixed liquor is squeezed out: with large-scale squeezer
Tobacco leaf clast or fine item are squeezed out into level-one mixed liquor；Four, level-one mixed liquor the separating clarifying of mixed liquor: is subjected to primary filtration
Precipitating clarification, which is carried out, with centrifuge after biggish impurity out obtains second level mixed liquor；Five, it separates waxes: second level mixed liquor is dropped
Low temperature obtains three after being separated by filtration out by the waxes of precipitation to 0 DEG C of < second level mixed liquor temperature <, 8 DEG C of precipitation waxes
Grade mixed liquor；Six, extraction and separation go out tobacco tar: three-level mixed liquor being transferred to extraction cylinder, using Co 2 supercritical fluid
Extraction and separation go out tobacco tar.
The beneficial effect that a kind of nicotine tar extracts technology of preparing is: a kind of nicotine tar extracts technology of preparing can be to big rule
The eucalyptus branches and leaves of mould carry out squeezing extraction, and entire extraction process carries out in low temperature environment, do not change the property of eucalyptus oil；
By taking sulfur dioxide supercritical extraction to the juice that the processes such as waxes obtain is filtered and be precipitated after squeezing, using natural
Product deliquescent difference, substance required for being extracted from plant material in the carbon dioxide of various different physical states；
Co_2 supercritical fluid extraction method is applied to the fragrant volatile oil of extraction, and having prevents the prominent of oxidation, pyrolysis and raising quality
Advantage out.
